Answers You Need

Here you can find a number of frequently asked questions related to our products and our services. We have tried to include a wide array of questions and answers, but if you still have a question that we haven’t answered, please get in touch directly and we will be happy to try and answer it in person.

Important Instructions

All diamond products need a slight break-in period. This is especially true with 6 micron and finer micron products. This occurs due to the diamond being micronized. The diamond is separated by a water process to size the particles. When the articles dry,they sometimes form a vacuum between each other. The result is deep scratches until the vacuum is broken down by use. The way to do dress the discs is to run a piece of fine aluminum oxide (dressing stick) over the surface for five to ten seconds. This effectively breaks down the vacuum and should eliminate the cratches. Be sure to follow this procedure using lots of water to flush the disc or belt. This hould take care of the scratching problem.
To insure maximum performance and long life from your new diamond abrasive belts and discs, please follow these instructions carefully.
1. There is a short break-in period, as with all diamond products. Use a light touch at
the beginning, since a new belt will cut much more aggressively.
2. These diamond abrasives must be used wet. The more water coolant used the
better. This is the most important factor in using your new belts.
3. Do not force sharp edges into the abrasives; this will cause tears in the backing.
4. Use light to medium pressure for best results and to ensure long life of the product.
5. Use the whole surface of the abrasive, never just one spot. Take advantage of the
fact that the entire surface is coated with diamond abrasive. This is the second most
important factor after using sufficient water coolant.
6. Be sure a belt is completely dry before storing in an enclosed space.

When ordering custom diamond products should I contact a distributor or contact FLEXIBLE DIAMOND PRODUCTS Directly?

If you are under a time constraint, it is easier and faster for us to discuss your custom order with you directly and put your order in immediate queue for manufacturing. However purchasing directly from us in minimum order quantities is more expensive than ordering from our distributors, because in general they sell our products at less than list price.


Failure to follow instructions and safety information can result in personal injury. Sanding with any power tool can be hazardous to the operator or to bystanders. When using abrasive products on power tools wear dust mask, eye, face and body protection at all times. Observe all procedures and safety information supplied by the manufacturer of your power tool. The dust emitted by wood, plastic, metal or paint can be hazardous to your health. Always wear proper dust mask.

Usage and Safety Safety

Always be sure to use the proper personal protection equipment, when using any grinding or polishing machines. Be sure to use adequate ventilation for the process you are performing. Be sure to only use products that specifically fit the intended machine. Inspection: Always check any belts or wheels for cracks, splits or any other imperfections that may affect the integrity of the product. Failure to do so may result in damage to your machine or person. PLEASE NOTE: It is NORMAL for the joints to show wear before the belt. Mounting: Only mount belts, wheels, drums etc. to machines for which they are intended. If any wobbling, vibration, or unusual noise occurs, stop immediately and check the mounting procedures for the piece of equipment being used. Storage: We highly recommend storage of our Flexwheels in a horizontal position (laying flat). Failure to do so can result in warping. We also do not recommend wrapping them in any tight plastic wrap as this places undue stress on the rubber and the belt resulting in permanent damage. Coolant: All products manufactured by Eastwind are meant to be used WET. Water is the best coolant to use. Water clears the slurry away from the work piece, reduces friction and heat which prolongs the life of our product. Please remember, the more water used, the better the performance. PLEASE NOTE: Eastwind Flexwheels are NOT meant to replace Metal Bonded Grinding Wheels. Flexwheels manufactured by Eastwind are Resin Bonded to a cloth backing.
