How to use Hand Profilers

With DAMO Hand Profilers, an operator with little or no fabrication skills can easily create a perfect edge profile of Ogee, Bullnose, Bevel or Roundovers. The DAMO Profilers may be used on the materials as follows: Granite, Engineered Stone, Porcelain, Marble and Limestone. Can be used on concrete also, but life will be short due to the abrasive nature of concrete.

DAMO Profilers can be used on any polishers or grinders with 5/8"-11 threaded spindles. A center water-feed polisher with 3500 RPM is recommended for the application. Optimal speed 3,500- 4,000 RPM. Adopting the latest “Vacuum Brazed Technology”, our profilers give you aggressive grinding action and longevity, without losing the shape of the profile, unlike the Sintered profilers on the market.

Press nylon guide down firmly on top of material and turn on polisher. Always apply sufficient downward pressure to prevent Nylon guide from spinning. (Nylon Guide should not "Spin Freely" during operation). Purpose of nylon guide is to assure the Profiler remains at the proper height so the profiled edge remains straight. The ball bearing/rotary touch within the Profiler will control the depth of grinding action to ensure the profiled edge remains straight and consistent. Application is complete when the operator can no longer hear grinding noise, and runoff water is clear.

How to use Wet Polishing Pads

If you need shape the edge of stone, use a DAMO Hand Profiler, or a DAMO Router Bit before polishing with Wet Polishing Pads.

DAMO wet pads are designed to be used on a center water-feed or external water-feed polisher or grinder. This tool distributes water evenly on the disc. The optimal polishing speed is around 3,000 RPM for most granite countertops. Engineered stone polishing may best work at a lower 2000 RPM. Do not run on high-speed machines that run above 4,000 RPM which will cause the disc to burn the stones. A DAMO variable speed wet electric polisher is recommended for wet polishing. DAMO wet pads are designed only for hand polishing applications. Do not use these discs on a floor polishing machine.

Fabrication is easier, faster and much healthier when the material is worked wet with a quality diamond system. Inhaling dust generated by dry polishing techniques is very unhealthy. A higher quality polish is obtained with wet polishing. Using proper attire and equipment such as rubber boots, safety glasses and an apron, will keep the user dry.

Connect a DAMO Back Holder to the polisher, and attach a DAMO Polishing Pad to the back holder. When attached to a semi-rigid or super flex back holder, the pad can be used to polish curves and Bullnose edges. When attached to a rigid back holder, the pad can be used to polish flat areas and straight edges. For tight areas such as corners, we recommend using an undersized backer holder to give the pads more flexibility. Turn on the water supply, you are ready to start the polishing.

Start the polishing process by using the DAMO wet pad grit 50 to remove all scratches or saw cut marks. While moving a spinning pad up and down, the fabricator moves the polisher across and back over the stone edge. An average of 2 to 3 passes is all you need. Moving two passes across and one pass up and down is a good technique and will usually provide an adequate amount of polishing time. After each step, you should make sure the area is smooth and there are no grinding marks or saw cut marks left over from the previous grit, then move to the next step. Repeat the same process using all 7 pads to complete the polishing process. Polish with the DAMO polishing pads: 50, 100, 200, 400, 800, 1500 and 3000 Grits in order. Do not skip any grits.

Turn off the water supply on grit 1500 and 3000.Wet the surface with a small amount of water. Polishing with grit 1500 until the area you are working on becomes dry. Wet the material once again with a small amount of water, continue polishing with grit 3000 until you achieve the high gloss and luster on the material.

How to use Dry Polishing Pads

If you need shape the edge of stone, use a DAMO Hand Profiler, or a DAMO Router Bit before polishing with Dry Polishing Pads.

DAMO Dry Polishing Pads are designed for use on jobs without using water, but polishing with a small amount of water to wet the object surface will ultimately reach a better result. Dry pads are also ideal for light color stones. Just like using the wet pads, the operator moves the dry pads across the object while in up and down motion. It is important to make sure all prior scratches are removed before moving onto next grit. Very little pressure is needed as the high quality diamond grit does the job for you. Avoid sharp corners of the stone to prevent any damage to the disc. The optimal polishing speed is around 3,000 RPM for most granite countertops. Engineered stone polishing may best work at a lower 2,000 RPM. Do not run on high-speed machines that run above 4,000 RPM. Ware a gauze mask to avoid inhaling the dust.

How to use Buff Pads

DAMO Buff pads are used as the last step if you want to achieve the mirror effect polishing result on granite or other natural stones. Black Buff is for dark stones but is generally OK for light color stones in most cases if you want to give the stones a slightly darker look. We suggest that you test the Black Buff on scrap pieces of material if you think the stone may be too light in color as it may darken the material during the buff process. On Absolute Black Granite, use the Black Buff longer than you normally do on other granites. This will enhance the depth of color and increase the gloss. White Buff is for light color stones.

Never use the Buff pads completely dry without using any water.Wet the workpiece and run the Buff pad semi-wet with very low water for lubrication to generate heat. When the water starts to evaporate, the Buff pad will create friction on the material, which will cause the material to start to heat-up and create the high gloss and color.


DAMO Buff pads should not be used on engineered stone material, or concrete. The purpose of using Buff is to generate heat build-up to create high gloss and color on natural stones, especially on granite. We recommend using semi-rigid or super flex back holder with Buff pad. The flexibility of the rubber back holder helps the Buff pad to heat-up the material quicker.

How to use Grinding Wheels

DAMO Turbo Grinding Wheels are designed for profiling edges, smoothing out inside sinkhole cuts, smoothing rough surfaces, preparation of material for lamination and heavy stock removal.

They perform exceptionally aggressive and endurable due to the latest “Vacuum Brazed Technology” and the turbo design. They are the premium choice for any grinding, shaping or beveling work.

They are designed for dry applications but work very well during wet applications. They can be used on most popular high-speed angle grinders with 5/8”-11 threaded spindles.

The coarse type (diamond grits 30/40) is used for aggressive grinding. The medium type (diamond grits 70/80) is for slower grinding action.

Attach the DAMO Grinding Wheel to your high-speed angle grinder.

Always refer to the operation manual of the power tool for correct mounting procedures.

DAMO Flat Grinding Wheels are designed for lightweight grinding and shaping work on marbles and granites. They can be used for cutting application as well. Adopting the “Vacuum Brazed Technology”, they provide fast stock removal with little or no operator fatigue. They are versatile and long lasting.

Available in 4” and 5” size with a coarse or medium grit, DAMO Flat Grinding Wheels fit on most common angle grinders and wet polishers with 5/8”-11 threaded spindles. They can be used wet or dry.

How to use Dry Core Bits

DAMO Dry Core Bits are designed for use on the job site without using water. When an installer has to make an additional hole or two, they cannot use water since the stone is already installed and using water will be difficult and costly due to the time consuming clean-up. Although these core bits are designed for dry use, wet cutting is recommended whenever possible.

Attach the DAMO Dry Core Bit onto your high-speed angle grinder by threading it onto the 5/8”-11 spindles. Mark the location of holes that need to be drilled. Use a template as a guide on the stone in order to avoid any mistakes during drilling process. Clamp a piece of stone scrap under the stone being core drilled to prevent excessive chipping or “blowout” on the back side of the stone. Proceed with drilling, pressing steadily until the dry core bit drills through the stone. When drilling multiple holes, cool off the dry core bit by dipping it in cool water after each drilled hole.

When you drill a hole freehand, it’s better to rock the power tool in a circular motion. Doing so will enlarge the size of the hole and maintain good cutting action of the diamond segments.

Sometimes the stone plug remains stuck inside the core bit. To remove it, tap onto the core bit while it’s mounted on the tool with a wrench.

How to use Contour Blades

Attach the 5” DAMO Contour Blade onto your DAMO DWS-125 Wet Stone Cutter. Use the third flange provided with the DWS-125 Wet Stone Cutter when mounting the DAMO Contour Blade onto this stone cutter to insure adequate clearance. (The DAMO Contour blade can also be mounted onto high-speed angle grinders).

A total of three passes should be used to cut 3cm (1-1/4”) thickness material. On the first pass you need to score the material 1/8” from the drawn template hole making sure you are scoring inside the template hole. On the second pass you should cut half-way through the material, and, on the third pass the blade should be cutting completely through the material. Due to the manual operation, we recommend cutting 1/8” inside of mark of sink template to ensure good results. Always refer to the operation manual of the power tool for correct mounting procedures.

Although these contour blades are designed for dry use, wet cutting is recommended whenever possible to prolong the life as well as keep harmful dust out of the air.

Before you start using this product, we recommend practicing on scrap material to learn the necessary techniques required for the curve cutting application. This practice will make your cutting safer and enable successful results.

We recommend using the DAMO Hand Profiler Z-Series after you cut a sink hole. The curve cutting application leaves a curved cut surface from the design of the contour blade. The Profilers Z will clean up this leftover material to create a perfect 90 degree surface.

To avoid dropping the cut-out on your feet, always secure the projected cut-out area before starting cutting operation.

Do not use contour blades on high-speed angle grinders without the safety guard installed. Always wear personal safety equipment when cutting.

How to use Dry Turbo Blades

DAMO Dry Turbo Blades are recommended to be used on high-speed angle grinders or stone cutters rated for your blade diameter being used. For example, 5” diameter blade will fit the 125mm wet stone cutters or 5” angle grinders. When mounting the blade onto the power tool, make sure the blades rotation direction matches the spindle’s. Do not use a slow RPM power tool, it will cause the blade’s cutting edge to become out-of-round or create premature wear on the blade.

DAMO Dry Turbo Blades can be used to cut tile, brick, block, concrete, slate and natural stone, and achieve superior results on granite.

Use of water will prolong the life of the dry cutting blade as well as eliminate the dust.

We recommend the step cutting method to prolong the life of the diamond blade. While cutting thick material, back off frequently to cool off the blade and prevent over-heating. Use flanges and adapters which are specifically made for your power tool. Always refer to the operation manual of the power tool for correct mounting procedures.

Always make sure the power tool’s safety guard is mounted onto the tool. If the blade doesn’t fit with the safety guard on the tool, you’re probably using the wrong size power tool.

The cutting edge rim height is 8mm. Bore size is 7/8" to 5/8" with washer, with/without four pin holes.

Always wear personal safety equipment when cutting.

How to use Router Bits

Adopting the latest “Vacuum Brazed Technology”, DAMO Multilayer Vacuum Brazed Router Bits are the best bits on the market. Compared with the sintered router bits, they achieve a longer life and have much faster profiling on granites of all hardness and all brands of engineered stone and quartz surfaces. They will not lose their shape after a period of using unlike the sintered router bits.

DAMO Monolayer Vacuum Brazed Router Bits are much cheaper than the Premium Router Bits. They are cost-effective for fabricators who wish to speed up the profiling. The Economy Vacuum Brazed Router Bits have been proven to grind in half the time of Premium Router Bits in most cases. They never lose their shape during shaping process.

Both M8 and M10 bolts are provided to fit all standard portable stone routers. They are available in most popular edges' shapes, such as A, B, E, F, V. Contact us if you ask for a special custom shape.

Cut the workpiece to size.

Attach the DAMO Router Bit onto your portable router.

Adjust the height of the router bit to desired position for edge you are creating.

Adjust the water spray nozzles to assure that proper lubrication coolant is being supplied to the router bit.

Start your project.

Always refer to the owner’s manual for proper usage and attachment of accessories onto the power tool.

The ball bearing/rotary touchier within the Router Bits controls the depth of grinding during the application to ensure the final profiled edge will be straight. Note: Profiling is complete when you no longer hear grinding noises and the runoff water is clear.

When changing router bits on your router, always test on a scrap piece of material to assure wheel is adjusted properly for the edge design you are going to grind

How to use Suction Cup

Instruction for Vacuum Suction Cups

Load and Environmental Conditions
Use the cup on clean, relatively smooth, nonporous surfaces, at temperatures from 10° to 120° Fahrenheit [-12° to 49° Celsius]. Moisture or contaminants can reduce the slip resistance of the cup. The red-line indicator may not perform reliably at elevations above 5000 feet [1524 meters]; see Service.
To Attach

1) Position the hand cup on the contact surface so the red line will be visible if it should appear while lifting the load. CAUTION: Test the cup for staining or deformation of load surfaces with light colors or soft coatings.
2) Pump the plunger until the cup attaches completely. When the red line is hidden, vacuum is sufficient for lifting.
3) Check the plunger frequently to make sure the cup remains securely attached. If the red line appears while lifting, set down the load immediately and pump the plunger until the red line is hidden again (see WARNINGS).
To Release
1) Set the load on a secure support.
2) Press the valve release lever (on other cups) until the cup disengages completely.
CAUTION: Remove the cup when not in use.

Since aging and wear reduce the capacity of the rubber pad, it should be replaced at least once every 2 years or whenever damage is discovered (see Inspection). If the hand cup does not function normally, the cup face may be dirty or the cup may require service. First clean the cup face according to the directions to follow. If the condition persists, contact us immediately for assistance.
1) Remove the air filter from the cup face.
2) Use a clean sponge or lint-free cloth to apply soapy water or another mild cleanser to the cup face. CAUTION: To prevent liquid from contaminating the pump, hold the cup face-down or cover the suction hole in the filter recess.
3) Wipe all residues from the cup face.
4) Allow the cup to dry and reinstall the air filter.
Examine and test the cup regularly to make sure it does not exhibit the following faults:
- cuts or damage to sealing edges of rubber pad.
- cracks or dents in handle or pump.
- reappearance of red line soon after attaching cup.
- sluggishness or dramatic changes in pump action.
- excessive glaze or stiffness of rubber pad.
- air filter missing from cup face.
Correct any faults before using the cup (see Service).
Store the cup in clean, dry condition.
Failure to observe WARNINGS could damage the hand cup or the load, or cause injury to the user.
- Do not use the cup to lift loads that exceed the Maximum Load Capacity or the effective capacity (see SPECIFICATIONS).
- Do not use the cup to support a person.
- Do not place the cup face against surfaces which could damage the sealing edges.
- Avoid conditions that could cause the cup to slip or to disengage prematurely, such as: contaminants, cuts or scratches in the cup face or contact surface; applying the cup to porous materials; or applying pressure against the cup edge.
- Do not use the cup to lift when the red line is visible. If the red line reappears frequently, discontinue use and see Service.
- Do not allow anything to interfere with free movement of the plunger while the cup is attached.
- Do not touch the valve release lever while lifting.
- Do not attach 10" [25 cm] diameter cups to thin, fragile materials.
- Do not use harsh chemicals (such as solvents or gasoline) or unauthorized rubber cleaners and conditioners to clean the cup.
