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.


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.

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.

  • What is an abrasive belt?
    Abrasive belts consist of abrasive grains applied to a backing made of cloth, film, foam and sponge, paper, or ot. her material. Abrasive belts are mounted on rotating wheels or pulleys and are used in applications such as surface finishing, sanding, and grinding.
  • What type of sanding belts are best for wood?
    Aluminum Oxide Sanding Belts Aluminum oxide usually appears with a distinctive red / brown color that is arguably the most popular sanding belt for wood that's available on the market today. It's achieved this popularity by being so affordable, durable, and efficient at sanding wood as well as metal.
  • What are 10 examples of abrasives?
    Abrasive minerals Calcite (calcium carbonate) Emery (impure corundum) Diamond dust (synthetic diamonds are used extensively) Novaculite. Pumice. Iron(III) oxide. Sand. Corundum.
  • What is the difference between a sanding belt and orbital sander?
    Whereas belt sanders are aggressive, orbital sanders, also called jitterbug sanders, are gentler, removing thin layers of material to provide a smooth surface.
  • What type of sanding belts are best?
    Aluminum oxide belts are the most common and least expensive type of sanding belts. Aluminum oxide belts are a good starting point for most wood and metal applications. Zirconia belts (also referred to as zirc or zirconia alumina) work best under high pressure and are ideal for coarse to medium grit metal applications.
  • What grit is best for sanding raw wood?
    For closed-grain woods (such as Cherry, Pine, Maple, Birch or Alder) that will be stained with water-based products use 150-grit followed by 220-grit. For open-grain woods (such as Oak, Ash, Mahogany, Parawood) that will be stained with water-based products use 120-grit, followed by 150-grit, then 180-grit.
  • What is the Diamond sanding abrasive belt
    Diamond sanding abrasive belt is a kind of coated abrasive tool, which is superhard material (synthetic diamond) abrasive particles adhesive to the flexible base by the bond.
  • What are 5 examples of abrasive?
    Rottenstone, whiting, pumice, volcanic ash, quartz, marble, feldspar, and silica are prime examples of an abrasive. Sandpaper, plastic and nylon meshes, and steel wool are also abrasives.
  • What grit is best for sanding hardwood?
    Your floor needs to be sanded in stages with progressively finer abrasives for the best finish. Starting with grit 40, then grit 60 and finally grit 100 is tipically a good procedure for most wood floors. The goal with the first coarse abrasive is to remove the old surface coating and to flatten the surface.
  • What is the most commonly used abrasive?
    Widely used abrasive particles in USM processes are boron carbide (BC), silicon carbide (SiC), and aluminum oxide. For machining hard materials, boron carbide is preferred, which also offers high material removal rate (MRR) as well.
  • What are the four main types of abrasives?
    The four types of abrasives include: Natural Abrasives. Synthetic Abrasives. Bonded Abrasives. Coated Abrasives.
  • What type of sanding belt is best for metal?
    So, what are the best sanding belts for metal? A sanding belt for metal is designed with ceramic, zirconia, aluminum oxide, and silicon carbide abrasive grains. Zirconia and Ceramic abrasive grains are considered as most effective sanding grains for metals. They both last longer than aluminum oxide and silicon carbide.
  • What is abrasive and examples?
    abrasive, sharp, hard material used to wear away the surface of softer, less resistant materials. Included within the term are both natural and synthetic substances, ranging from the relatively soft particles used in household cleansers and jeweler's polish to the hardest known material, the diamond.
  • Where can Which sanding belt lasts the longest? I add my FAQs?
    In terms of lifespan, ceramic grains also have the longest lifespan over other common abrasive grains. Ceramic sanding belts can last up to three times longer than zirconia sanding belts and up to five times longer than aluminum oxide sanding belts.
