Swirl-Free Air-Powered Disc Sanders
For a more consistent finish than rotary or orbital disc sanders, these move sanding discs in small irregular circles to prevent swirl marks. Also known as random orbital sanders. They work with either adhesive-back discs or hook and loop discs.
Medium duty sanders work well for general purpose sanding. To adjust how much material they remove, turn the dial with your thumb as you sand to change the speed. Heavy duty sanders can be used continuously to sand most surfaces. They run at a steady speed and balance power and weight, so you can achieve your finish faster than light and medium duty sanders. They'll maintain speed when sanding tough surfaces.
Sanders with a 3/8" orbit diameter are good for aggressive sanding, such as shaping material. They remove material the quickest and leave the coarsest finish on your work surface. Sanders with a 3/16" orbit diameter balance removal speed with finish quality and leave you with a moderately smooth finish on your work surface. Sanders with a 3/32" orbit diameter remove material the slowest but leave the finest finish on your work surface.

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 adhesive-back discs come with a backup pad for use with adhesive-back discs.
Sanders for quick-change discs are used with Style B quick-change discs and require a backup pad (not included).

Heavy Duty Air-Powered Disc Sanders

For tough jobs, these sanders use roughly 1.5 times more air than standard air-powered disc sanders. Made with a steel housing, they’ll hold up to bumps and scuffs in environments as rugged as foundries. They’re often used to remove flash, which is the metal that seeps out of die cast molds. Their high air consumption makes the steel cold, but a rubber housing protects your hands and also reduces vibration. These sanders move in a fixed rotary motion, so they remove more material from your work surface than random orbital sanders. However, this means they can leave swirl marks on the surface. Use with Style B quick-change discs (not included).

Cordless Disc Sanders


For quick jobs where you don’t have access to a power source, these sanders are battery-powered. They’re more aggressive than orbital disc sanders—they use rotary motion to remove material faster. The rotary motion may leave swirl marks on your work surface. All require quick-change sanding discs or hook and loop sanding discs. You can also use them with quick-change polishing pads to polish your surface.
These sanders have a brushless motor that reduces friction to optimize battery life. They’re durable; they run cool and have few moving parts that require maintenance. An LED light illuminates your work surface and reduces shadows for easy viewing. Adjust the side handle to keep your grip steady in multiple positions.
Use them with an Ingersoll Rand 20V DC battery and charger you already have or choose the sander that has batteries and a charger included.

Cordless Swirl-Free Disc Sanders
Create a consistent finish on quick sanding jobs where you don’t have access to air or electric power. Also known as random orbital sanders, they move in small irregular circles to leave a more consistent finish than rotary disc sanders. The variable-speed motor lets you set the speed for any task, from heavy material removal to delicate surface sanding. To conform to curves and crevices for a consistent finish, they include a cushioning pad. Use these sanders with hook and loop sanding discs. The battery and charger are also sold separately.
To remove dust from the air and extend the life of the sanding sheet, these sanders have a dust collection bag.

These sanders have a dust collection hose adapter that connects to a vacuum for an alternative to the collection bag or canister.
2535-20 sanders have a brushless motor that reduces friction to optimize battery life. The motor runs cool and has few moving parts that require maintenance. An LED light illuminates dim workspaces and reduces shadows, so you can see your work.

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.
Backup Pads with Shank for Quick-Change Sanding Discs
Secure the shank into the collet or chuck of your tool and attach the quick-change fastener on the back of compatible sanding discs to the pad.
Pads with soft density conform to contoured surfaces and are good for polishing and finishing. Pads with medium density provide enough support for heavy material removal but are flexible enough for contouring and shaping. Pads with hard density hold their shape as you apply pressure and are the best option for aggressive material removal.
