Stearate A/O and S/C are dry sanding types of sandpaper. Stearate A/O (Aluminum Oxide) primarily used in bare wood or non-ferrous metal applications where loading of the material could occur. Stearate S/C (Silicon Carbide) is primarily used in between coats of finish. The added stearate acts as a dry lubricant while sanding on surfaces where wet sanding cannot be applied. Stearate S/C is not recommend for bare wood sanding and SOME water based finishes. Instead look at our regular wet/dry S/C for water based finishes.

If you're using water based finishes and have questions, please contact our technical department before finishing your project.

Yes. Sanding is simply the removal of material through friction. Keep in mind the holes are an added benefit for you. The holes are used to extract the dust/loading of material you have removed with the sandpaper. If you notice swirl marks in the piece you are sanding, you will want to wipe the surface between grits or get dust collection.

No. Joining a belt together is a very precise process. It uses a special epoxy with tape to create a lasting joint. The biggest environmental threat to the tape joint is moisture. We recommend that you do not hang portable belts on a hook or peg. Instead keep your belts in a plastic bag or in a climate controlled area. Typical standard life of a belt joint is one to two years.

A very easy and helpful solution to belt loading is a "rubber cleaning stick." This rubber-based stick, item #'s BS99116 - BS99801 - WK30030 - WK13100, are held against the loaded belt as it is running. The rubber pulls out trapped sanding residue impacted between the abrasive grains, thus increasing the belt life. Also useful for Drum Sanders, Long and short belts, Discs and Fibre Discs.

This problem can be easily remedied with KLINGSPOR's Mac Mop. This wheel consists of hundreds of small abrasive strips bonded to a strong epoxy core. Typical applications include the sanding of turned wood parts, scuff sanding of sealer coats, satin finishing of metal parts, mold sanding and sanding of virtually any profile. Mac Mops are available in two sizes: 10" x 2" and 10" x 4" and in grits ranging from 80 to 180. They are best used on a motor with at least a 3/4" diameter spindle and operate at between 1100 rpm and 3000 rpm.

YES. We do offer Belts in just about any size. You will need to call in to our customer service department (800.228.0000) for a custom size quote. You will need to know the size of the belt you need. If you are not sure, there are one of two ways to measure. You can measure an existing belt by laying it flat, measuring the width, then the length and multiplying the length by 2, or cutting it and measuring the overall length. You can take a string and wrap it around the machine in the normal position the belt would be in and then measure the string. Custom belt orders usually take 3 to 4 business days to manufacture and ship out.

F.E.P.A. - "Federation of European Producers of Abrasives." Normally used to describe a European grading system for abrasive grain to differentiate it from the US A.N.S.I. system. Products graded to the F.E.P.A. system have the letter "P" prior to the grit designation. Another grading system is C.A.M.I., which is, "Coated Abrasives Manufacturers Institute." A trade association composed of US coated abrasive manufacturers. This will not have a P in front of the grit.

The recommended abrasive varies depending on the material being sanded. For ALUMINUM, CAST IRON, CHROME, & STEEL the best product would be Alumina Zirconia for rough grinding and Aluminum Oxide for general purpose grinding and finishing. Silicon Carbide is sometimes used for final finishing. For WOOD the best product is Aluminum Oxide for general purpose sanding. Alumina Zirconia can be used for planing operations and Silicon Carbide is often used when working with particle board. For GRANITE or other stone material we recommend Silicon Carbide almost exclusively. Usually ground wet to reduce dust and eliminate burning.

Open Coat is a coated abrasive product in which the abrasive grain covers approximately 50% to 70% of the coated side surface. Helps to retard loading of sticky or gummy materials such as softwoods or paint. Closed-coat is better for sanding metal and wood finishes but clogs easily with sawdust.

Alumina Zirconia: A high-performance alloyed abrasive formed by Zirconia deposited in an Alumina matrix. An alloy of Aluminum Oxide and Zirconium Oxide. Designed for heavy duty stock removal for metal and wood, with self-sharpening characteristic. Belts are normally blue in color. It normally works well for grinding stainless steel, spring steel, titanium and other hard metals and for dimensioning wood. Comes in Belts, Discs, Fibre Discs, and wraps for your drum sander.

Aluminum Oxide: An abrasive made by fusing the mineral bauxite. A very strong and tough abrasive. The most commonly used abrasive for wood and metal. Normally brown or reddish-brown in color. Usually it is best suited for sanding metals, wood and solid surface. Comes in Belts, Sheets, Sleeves, Rolls, and even several options in the form of discs.

Zinc Stearate: A dry lubricant added to the surface of coated abrasives (usually sheet or disc goods) which prevents loading of soft materials such as paint and other finishes. Normally white-gray in color.

Silicon Carbide: An abrasive made from coke and silica sand. Very sharp and hard abrasive. Used for sanding between coats of finish, painted or otherwise finished surfaces, rubber, plastic, non-ferrous metals and other types of materials. Cuts very well under light pressure. Has self-sharpening properties and normally black in color.

Garnet: A very sharp grain that cuts very quickly when new. It fractures quickly, keeping it sharp. it is perfect for sanding wood end grains or for final finish sanding of wood. Garnet is very economical. Mostly found in sheet form.

In the premium you get our best backing material, while in the bargain box you can get several different backings but all are still cloth aluminum oxide. The Economy belts have a more pliable backing than the premium belts and they are still aluminum oxide and you get a consistent quality each and every time.

You could use a fiber disc, angle grinder flap wheel, or flap disc on a right angle grinder for the actual cutting. You can also use products like Arbortech Turbo Plane. That would be the quickest. Also depending on how deep you need to go, probably start with 60 or 80 grit and then adjust up or down based on removal rate.

Usually products that have been chemically treated to be waterproof (i.e. they will often have a WP or "waterproof" designation on backing) and all our polyester backed products which are inherently waterproof. Please check with our customer service for more information to best choose the right product for your application.

We recommend you never skip more than one grit as you work up through a grit sequence. When you do, you overwork the finer grit by asking it to remove a scratch it is not designed to remove. This can result in burning of the work piece, belt and lower abrasive life.

There are two sizes of 3x9 pump sleeves. One is for an American drum and the other is for a drum made in China. Pump sleeves are measured like a belt. You can measure an existing sleeve by doing the following: lay the sleeve flat, measure the overall length, and then the width multiplied by 2. If you don't have a sleeve, you can wrap a string around the outer (metal) part of the drum and measure the string.

Heat is the main culprit that causes clogging. The best way to remedy some of this is to make light passes and use a belt cleaning stick periodically to remove any built up particles in the abrasive. Dust build-up can also contribute to abrasives clogging and burning. Using a good dust collection with at least 1,000 cfm is ideal, as drum sanders produce a tremendous amount of dust that needs to be extracted. A shop vac just won't handle the amount dust that is created. A side note - Be sure to have decent filtration (30 micron or better) on any dust system you may use. Also make sure your wraps are not touching each other when on the drum. Keep at least a 1/16” gap between wraps. This will aid in cooling and dust removal from the sanding process.

The shop rolls are too flexible and will stretch out from the heat on a drum sander, which would translate into wrinkles and binding of the cloth backing.

We have several options that will work when a food safe finish is required.

If the stain comes out too light, then you may have sanded to smooth. Typically the best overall color achieved with staining is after 180grit sanding. Any finer and you are burnishing the wood causing your stain to not penetrate or be of a darker color. If the color is light and dark or “Blotchy” on the wood, then you can add a pre-conditioner before staining.

Complete Volatile Organic Compound (VOC) limits can be found at The states that have VOC limits are as follows: California, Conneticut, Delware, Maine, Massachusetts, Maryland, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Northern Virginia, & Washington D.C.

The problem could be the wood grain, density of the wood, or glue has gotten on the surface of the wood.
