3M 7010331286 Slotted Cloth Disc 1 Inch 120 Grit

Product Description

The 3M 7010331286 is a silicon carbide slotted cloth disc designed for use in push applications where full contact with internal surfaces is required. The slotted construction allows the disc to compress when inserted into a hole, cylinder, or bore, conforming to the internal radius for consistent, even abrasive action. At 1 inch in diameter and 120 grit, it is suited for light deburring, blending, cleaning, polishing, and chamfering on stainless steel, ferrous metals, and softer workpiece materials. A threaded eyelet arbor hole accepts a compatible mandrel for use with a rotary tool or drill. Rated at 1,965 rpm maximum operating speed. Licensed tradespeople and maintenance technicians working on tight-tolerance interior surfaces are the primary users.

This disc is used wherever a small-diameter abrasive must reach inside a drilled hole, pipe end, cylinder bore, or similar internal geometry. Common applications include weld blending inside tubing, chamfering hole edges on sheet metal or structural components, light surface conditioning inside fittings, and general cleaning of interior surfaces before assembly or inspection. It is sold individually and is appropriate for bench repair work, field service, or production deburring stations.

Key Features

• Slotted construction compresses in push applications for full contact with holes, internal radii, and cylinder walls
• Silicon carbide abrasive cuts stainless steel and softer surfaces while leaving a smooth finish
• Cloth backing resists tearing and fraying for extended service life
• 1 inch diameter at 120 grit for light material removal and surface blending
• Threaded eyelet arbor hole for secure mandrel attachment
• Rated at 1,965 rpm maximum operating speed

Compatibility

Designed for use with compatible mandrels sold separately. Select a disc diameter at least 0.5 inches smaller than the internal diameter of the workpiece to allow the slotted construction to compress and make full contact.

Installation Notes

This disc is installed by threading the eyelet arbor hole onto a compatible mandrel before mounting to a rotary tool or drill. Ensure the tool speed does not exceed the rated 1,965 rpm maximum before operation. Secure the workpiece before contact and confirm the mandrel is fully tightened to prevent disc ejection. Wear appropriate eye protection and follow facility PPE requirements when using abrasive discs.
