Swirl-Free Air-Powered Disc Sanders

The orbital motion produces more consistent finishes than standard disc sanders. Also known as random orbital sanders. They work with either adhesive-back discs or hook and loop discs.
12 1/2"-long sanders give you more control than shorter sanders. They’re useful for sanding the vertical sides of workpieces because you can use two hands to control them.
Sanders with 3/8" orbit diameter are good for aggressive sanding, such as shaping material.
Sanders with 3/16" orbit diameter are useful for general purpose sanding.
Sanders with 3/32" orbit diameter are best for finishing pieces with ultra-fine sanding.

Static-Control Swirl-Free Air-Powered Disc Sanders

Dissipate electrostatic discharge (ESD) for safety when sanding. These sanders have a copper ground wire to divert ESD away from users, sensitive equipment, and combustible materials. They’re often used for sanding across multiple materials—such as wood to fiberglass—as doing so can generate harmful static. Connect the copper wire to the ground of either a vacuum system or an outlet. These sanders also have two 1-megaohm resistors for protection in case there’s accidental contact with an electrical current.
Also known as random orbital sanders, these sanders move in small irregular circles. No single part of the abrasive follows the same path twice, resulting in a swirl-free finish. This leaves a more consistent finish than rotary or orbital disc sanders. To prevent clogs and remove debris from your environment, attach these sanders to a vacuum system. Designed for heavy duty applications, these sanders are powerful enough to quickly remove lots of material without getting bogged down. And they’re lightweight, so they’re easy to control and won’t tire you out after long periods of use. Use with hook and loop sanding discs.

Air-Powered Disc Sanders
With a fixed rotary movement, these sanders remove more material from workpieces than random orbital sanders. However, they may leave swirl marks on the surface as a result.
Dust-collecting sanders have a built-in vacuum that connects to a self-contained dust-collection kit (sold separately). The vacuum prevents clogs to extend the life of your sanding discs and keep your workspace dust-free. The vacuum shroud is clear and has a view port so you can see the edge of your sanding disc as you work.
Sanders for quick-change discs are used with Style B quick-change discs and require a backup pad (not included).

Swirl-Free Electric Disc Sanders

Prevent swirl marks to leave a more consistent finish than rotary disc sanders. Also known as random orbital sanders, these sanders move in small irregular circles. No single part of the abrasive follows the same path twice, resulting in a swirl-free finish. A dust collection system draws dust through the sanding pad and into a collection canister. This keeps your work surface clean and reduces how much dust is kicked into the air. Use with hook and loop sanding discs.

Electric Sheet Sanders


With rapid back and forth movements in a straight line, these sanders remove more material than random orbital sheet sanders. Adjust their speed to fit your task. Higher speeds remove material quickly; lower speeds prevent damage and burns to delicate material. Rectangular in shape, they reach into corners and fit along edges better than disc sanders. A dust collection system draws dust through the sanding pad and into a collection canister. This keeps your work surface clean and reduces the amount of dust flying in the air. These sanders may leave scratches on your surface because they're moving so quickly. You can remove those scratches by sanding with a finer grit. Sanding sheets are sold separately.

Swirl-Free Air-Powered Sheet Sanders

Leave your material with a more uniform finish than if you used a standard sheet sander. Also known as random orbital sanders, these sanders move in small irregular circles. No single part of the abrasive follows the same path twice, resulting in a swirl-free finish. Because they are rectangular, they reach into corners and fit along edges better than disc sanders. Sanding sheets are sold separately.

Nylon Mesh Pad Sanding Blocks


Attach a nylon mesh sanding pad (sold separately) to these blocks for improved comfort and control. Teeth on the bottom of the block sink into the mesh of the sanding pad to hold it in place. Use them with pads at least the size of your block. They're most commonly used with standard 6” Wd. × 9” Lg. sanding pads.

Sheet Sanding Block Assortments

Keep a variety of sanding blocks on hand to smooth workpieces of all shapes and sizes. The blocks in these assortments are more comfortable to hold than a sheet alone and give you greater control while you sand. Larger blocks are good for finishing wide surfaces; smaller blocks squeeze into tight spaces. All are bright yellow, so they’re easy to spot in dusty shops. Pair them with adhesive-back or hook-and-loop sanding sheets and rolls (sold separately).

Disc Sanding Blocks for Wet Sanding
Keep the surface of your workpiece damp during sanding. These blocks have a sponge in the center that soaks up water or lubricant, then slowly releases it as you sand. This makes the surface of your sanding disc (sold separately) slippery, which helps prevent scratches. It also washes away dust and debris, removing clogs and extending the life of the abrasive. Made of firm foam, these blocks distribute pressure evenly across the surface of the sanding disc. They’re often used for surface preparation or finishing delicate materials.
Sanding Sheets for Oscillating Tools



Use these sheets with an oscillating tool—their triangular shape reaches into tight corners and spaces. With hook and loop backing you can quickly attach, remove, and reuse them with a compatible backup pad. Sheets have holes to allow dust removal when you connect your tool to a dust extractor and vacuum system to prevent buildup of debris on the abrasive surface. They also have a slick coating to further prevent dust accumulation.
Starlock-blade-mount sheets can be used with any Starlock-compatible oscillating tool. They are aluminum oxide, the most common choice for material removal and wood finishing.
Open-blade-mount sheets are compatible with any non-Starlock oscillating tool. They have ceramic alumina abrasive, which is sharp and dense enough to shape hard metals such as stainless steel, nickel, and iron without dulling quickly. It removes material faster and lasts longer than aluminum oxide but requires more force to abrade properly.
