Abrasive Material

Abrasive materials smooth the workpiece or remove material. Abrasives perform differently based on the workpiece material and is closely tied to the grit or grit grade of the abrasive.

Aluminum Oxide is a strong, sharp, and durable abrasive that penetrates the work surface and withstands heat and high speeds.
Silicon Carbide is a sharp synthetic abrasive that provides a fine finish in low-pressure applications such as finishing and painting preparation.
Ceramic self-sharpens faster than other abrasives to remove material faster and keep the surface cooler, which makes ceramic a good choice for heat-sensitive metals.
Diamond is a very hard abrasive used on a variety of hard-to-grind materials including nonferrous metals, glass, composites, chilled iron, and thermal spray coatings.
Garnet is a natural, sharp abrasive that won't leave scratch marks on bare and soft wood, such as pine and fir.
Emery is applied to a cloth backing to polish, smooth, and clean metal.

Abrasive Grade

Abrasive grade is a general classification of the coarseness of the grit. For coated abrasives, each grade includes a range of grits that are generally used for the same type of tasks. For nonwoven abrasives, grade is designated by the manufacturer.

Extra Coarse provides heavy material removal and removes heavy rust, coatings, and finishes. Extra-coarse grits range from 12 to 36.
Coarse provides moderate material removal, smooths rough surfaces, and removes moderate rust, gouges, and deep scratches. Coarse grade grits range from 40 to 60.
Medium removes light scratches, rust, and smooths imperfections. Medium grits range from 80 to 120.
Fine deburrs metal and smooths surfaces before final finishing. Fine grits range from 150 to 220.
Very Fine buffs metal and removes light paint from metal and wood. Very fine grits range from 240 to 280 (P240 to P320).
Extra Fine polishes metal and smooths raised wood grain. Extra fine grits range from 300 to 360 (P360 to P600).
Super Fine buffs metal and plastic, smooths finishes between coats, and removes fine scratches without removing stock. Super fine grits range from 400 to 600 (P800 to P1200).
Ultra Fine buffs metal to a high shine and polishes thick finishes.
Micro Fine polishes metal to a high-gloss shine and sharpens blades.

Abrasive Grit

Abrasive grit is the industry-determined relative grain size assigned to coated abrasives. Lower grits have larger grains and are used for heavy-duty applications. Higher grits are used for smoothing and finishing. The grain size gets smaller as the grit number goes up, indicating that the grain and abrasive surface are finer and less aggressive.

Three standards (CAMI, FEPA, and JIS) describe similar grits using different number designations. CAMI designations are indicated with a number alone, FEPA designations are preceded with the letter P, and JIS designations are preceded by the letter J. Grits preceded by M, used for diamond abrasives, indicate that the grit size is given in microns. Roughly equivalent grits are shown together below.

Backing Material Weight

Backing material weight indicates the thickness and durability of the adhesive backing. Paper backings are generally used dry, while cloth and film backings can be used wet or dry. Heavier backings are thicker and used for coarser grit and higher pressure applications than light, thinner backings.

A is the lightest paper backing (40 lbs.) and conforms to contoured surfaces. It is generally used with fine grit abrasives and hand-sanding applications.
B is a flexible paper backing (40 lbs.) that is slightly more durable than A-weight paper.
C is a 70 lbs. paper backing that is stronger, thicker, and less flexible than A- and B-weight paper. It is often used with small power sanders and is foldable for hand-sanding.
D is a 90 lbs. paper backing that is stronger, thicker, and less flexible than C-weight paper. It is often used for moderate and coarse grit sandpapers.
J is the most flexible cloth backing used for finish work and curved surfaces where material removal is not desired. Sometimes called jeans weight.
X is a moderately flexible cloth backing that balances blending with stock removal for the widest range of applications for cloth backings. Sometimes called drills weight, it is stiffer and less flexible than J-weight cloth.
