3M Random Orbital Palm Sander 5" — 3/16" Orbit Pneumatic, Low-Profile with Stikit Pad

The 3M 20317 is a 5-inch pneumatic random orbital palm sander with a 3/16" orbit that delivers swirl-reduced finishes for wood, metal and composite surfaces.

This air-powered, non-vacuum palm sander combines a compact, low-profile shape with a precision-balanced motor to give consistent, professional results in production and shop settings. Built with a lightweight aluminum housing and an internal muffler, the tool reduces operator fatigue and noise while accepting both Stikit adhesive discs and Hookit-style pads for versatile abrasive choices.

How does this sander produce a swirl-free finish?

The 20317 uses a dual-action random orbital motion that prevents a single abrasive path from repeating, greatly reducing visible swirl marks. Its 3/16" orbit offers a balance between material removal and a fine finish, suitable for final sanding before paint or clearcoat.

• Random orbital motion for overlapping sanding paths
• 3/16" orbit tuned for moderate cut and fine finish
• Precision-balanced motor to minimize vibration and pattern distortion

What air supply and operating specs are required?

This sander is designed for compressed-air operation and runs best at 90 psi with a required flow of 17 SCFM. Use a clean, lubricated supply line (minimum 3/8" hose recommended) and keep airline runs as short as practical to maintain performance.

• Rated at 90 psi and 17 SCFM (approximately 481 LPM)
• Maximum speed up to 12,000 RPM at rated pressure
• Recommended 3/8" (10 mm) airline, maximum 25 ft (8 m)

Which abrasives and backing pads work with this model?

The tool ships with a 5" Stikit low-profile disc pad for secure adhesion of adhesive-backed discs, and it also accepts Hookit-style pads so you can use Hookit abrasives or Scotch-Brite products. Choosing matched 3M abrasives optimizes cutting rate and finish quality.

• Included 5" Stikit disc pad (part 20351) for adhesive discs
• Compatible with Hookit pads and Scotch-Brite discs for added versatility
• Pairs best with 3M coated abrasives for predictable results

What features improve operator comfort and durability?

The sander's low-profile body, rubber grip and recessed lever platform reduce hand strain and eliminate common pressure points. An internal muffler lowers noise without adding external parts that can break off, while the aluminum housing keeps weight down and resists cracking during heavy use.

• Comfort rubber grip and recessed lever platform to reduce pinch points
• Internal muffler for quieter operation and fewer exposed parts
• Durable aluminum housing and composite cover for long service life

Who is this for: The 3M 20317 palm sander is intended for industrial and professional technicians who need a reliable, high-production pneumatic tool for surface prep and finishing on wood, metal, fiberglass and composites. It is designed for shop and production environments where dust extraction is not required and operators prefer an ergonomic, high-speed air tool that pairs seamlessly with 3M abrasives. Note: this model is for industrial/occupational use and not marketed for consumer retail.
