Sandpaper is available for sanding by hand and for use with power tools.
Hand-sanding products allows for better control and gives you the ability to reach areas that a power tool cannot. Hand sand wood as final preparation for finishes and between finish coats. Sandpaper for hand sanding comes in various sizes including the widely popular 9 x 11 sanding sheet. You can use some sandpaper for both hand sanding and power sanding.
Power-sanding products remove material quickly and efficiently. They are a good choice for getting rid of blemishes and for shaping and leveling wood. Power sanding is an effective method of preparing metal surfaces for paint. Sandpaper for power tools comes in sheets, discs and belts designed to fit specific power tools.
One way to determine which sandpaper will work best for a particular job is to know the abrasive materials and their properties.
Commonly used manmade abrasives:
- Aluminum oxide is a common sandpaper type that works on wood, plastic, metal and drywall. The particles break during sanding, constantly exposing new, sharp edges. Aluminum oxide sandpaper is long lasting, making it a popular choice for power sanding, but you can also use it for hand sanding.
- Silicon carbide sandpaper removes material more quickly than aluminum oxide, but doesn't last as long. Use it on wood, plastic and metal for tasks such as rough sanding, paint or rust removal and sanding between coats when finishing. Use it on drywall to smooth joints. Silicon carbide products often have a waterproof backing that allows you to wet sand. Wet sanding uses liquid to lubricate the work surface, minimizing scratches. This technique also helps prevent the sandpaper from clogging with dust, removes loose abrasive particles and reduces airborne dust.
- Zirconia alumina is suitable for wood, fiberglass, metal and painted surfaces. You'll find it in the form of belts, pads and discs for power sanding. Like garnet and aluminum oxide, the particles break during use, maintaining sharp edges that remove material quickly. However, zirconia alumina lasts longer than aluminum oxide.
Some papers use natural abrasives:
- Garnet is good for hand sanding. It works well on raw wood — removing light scratches and preparing the surface for finishing. The abrasive particles break during use, providing new edges for removing material, but garnet sandpaper wears quickly.
- Emery works for both hand sanding and power sanding metal. Use coarser grits to remove rust or paint and finer grits to polish. Emery sandpaper often has a cloth backing and is also known as emery cloth.
- Crocus cloth is an abrasive sheet similar to sand paper or emery cloth but covered with a layer of very fine loose iron oxide particles also known as Jeweler’s Rouge rather than with bound grains of abrasive. It is intended for final metal and gemstone finishing.
You may see sandpaper labeled closed-coat or open-coat. Closed-coat products feature abrasives covering all of the backing. This construction removes more material making it effective for hand sanding but can clog more quickly than open-coat products. Open-coat products have empty space on the backing, giving waste material room to accumulate without reducing performance. Since they don't clog as quickly, they are effective for power sanding. Additionally some abrasive paper products come with a stearate coating which can reduce loading.
Good to Know
Paper is a traditional backing for sandpaper, but you can also find cloth and film backing, which offer better durability. Unlike products with paper backing, you can use cloth-backed products are often water resistant and can be used for wet sanding.
What is Grit?
The grit number of an abrasive sanding product indicates the size of the abrasive particles. The lower the number, the larger the abrasive particles — they remove more material but create more noticeable scratches. A higher number indicates smaller particles, which don't remove as much material but leave a finer, more polished appearance. Sanding projects use several grit sizes, starting with lower-number grits and moving up the scale to finer, higher-number grits. Each higher grit removes scratches from the previous grit, creating an increasingly smooth surface.
Grit size ranges from 24 for heavy material removal to 2000 and beyond for working with automotive finishes. Grit numbers between 60 and 220 will handle most household projects.
The specific grit numbers you need vary by project and the material you're sanding, so follow the abrasive product manufacturer's recommendations. Below are some general guidelines:
Grit numbers from 36 to 100 are good for removing material and work well with power sanders. Applications include:
- Stripping away paint or varnish finishes
- Removing rust on metals or flaws in wood
- Leveling and shaping wood
Grit numbers from 100 to 180 perform well with both hand sanding and power sanding, preparing bare surfaces for finishes. This range is good for:
- Smoothing work pieces
- Removing scratches
- Final preparation for finishing
Grit numbers from 180 to 320 work for finishing. Hand sanding is good for these applications:
- Removing raised wood grain fibers
- Scuffing between finish coats

Grinding applications require mounted points that have a perfect balance in terms of chip performance, intended surface finish and service life. In foundries and mold forming operations, the use of mounted points on straight grinders and flexible shafts is often the only method of getting to hard-to-reach parts on workpieces and simultaneously improving the surface.For best mounted point performance, always run the mounted point at the maximum allowable speed according to AnSI B7.1.“W” shapes are best used for offhand and precision grinding of medium to heavy stock . The most commonly used mounted points are the A-1 Resin Bond Mounted Points, A-3 Resin Bond Mounted Points and the W220 Resin Bond Mounted Points. AA Abrasives resin bonded mounted points are made of premium aluminum oxide and designed for a high RPM die grinders. They are excellent for weld removal on hard to reach areas on metal and stainless steel.
AA Abrasives resin bond mounted points are made from Aluminum Oxide, these mounted points come with a 1/4" shank.
In the video below, a W220 resin bond mounted point is used on a Dynabrade 52678 Straight Line Extension Die Grinder to finish 304 stainless steel racks.

An abrasive flap disccan help you grind and finish metal surfaces with one tool attachment. Flap discs grind like a depressed center wheel and finish like a fiber sanding disc – helping you reduce process time and lower your total grinding costs.Technically speaking, Type 27 Flat flap discs have a flat flap design and provide the best finish. These tend to be the most popular and commonly used. Type 27 Flap Discs are used primarily on flat surfaces they grind at flatter angles 0° to 15°.Type 29 Conical flap discs are the more aggressive choice, with flaps angled at 10°. The angle provides greater surface contact. A Type 29 flap disc can be used on both irregular and flat surfaces and grinds at steep angles 15° to 25°.Choose an angled flap disc-Type 29 for faster stock removal. An angled edge can be used with a vertical or horizontal grinder. And with the angled edge, more of the abrasive disc contacts the metal surface, helping you strip and finish in less time.We only offer high quality flap discs because we have found that poor quality flap discs on the market tend to “chatter” during the grinding process and generate vibrations. This can result in the grit pulling away from the mounting prematurely giving you irregular grinding, poor grinding capacity, short service life and potential flap tearing. AA Abrasives Flap Discs are made with premium zirconia alumina grain on a phenolic backing. Zirconia-alumina is best for medium- to heavy-material removal. The grains constantly fracture to produce new sharp edges. Flap discs made from zirconia-alumina are commonly used on carbon steels, aerospace alloys, nickel alloys, aluminum, cast iron, forgings and some stainless steels. These flap discs are made in the USA.If you use flap discs - try our high quality flap disc line. Our most popular flap discs are the Zirconium in 4-1/2" and 7" with a 7/8" arbor hole.
