3M 7010368434 Ao Slotted Cloth Disc 1 Inch P180 Grit

Product Description

The 3M 7010368434 is an aluminum oxide slotted cloth disc engineered for push applications where full contact with internal surfaces is required. Measuring 1 inch in diameter and cut to P180 grit, this disc compresses as it enters a hole, bore, or cylinder, conforming to the internal radius for consistent abrasive contact. The aluminum oxide abrasive grain delivers reliable stock removal on a range of materials, while the cloth backing resists tearing and fraying under load. It is installed by trade professionals and industrial finishing technicians working on precision deburring, blending, cleaning, polishing, and chamfering tasks.

This disc is suited for light material removal and surface finishing work on steel, stainless steel, rubber, plastic, and composite materials. Its slotted design makes it a practical choice for internal diameter work on machined components, fabricated assemblies, and formed parts where a flat disc cannot maintain contact. The threaded eyelet arbor hole allows direct attachment to compatible mandrels, which are sold separately. It is commonly used in manufacturing, metalworking, and maintenance applications requiring a controlled, repeatable finish on inside diameters.

Key Features

• Slotted construction compresses in push applications for full contact with internal radii, bores, and cylinder walls
• 1 inch diameter with P180 grit aluminum oxide abrasive for fine finishing and light deburring
• Cloth backing adds durability, resisting tearing and fraying during use
• Threaded eyelet arbor hole for secure mandrel attachment
• Effective on steel, rubber, plastic, and composites
• Select a disc diameter at least 0.5 inches smaller than the internal diameter of the workpiece

Compatibility

Designed for use with compatible mandrels available separately. Select a disc diameter at least 0.5 inches smaller than the internal diameter of the workpiece to allow proper compression and full abrasive contact.

Installation Notes

Thread the eyelet arbor hole onto a compatible mandrel before mounting in a rotary tool or die grinder. Confirm the mandrel is rated for the intended RPM before operation. Power down and disconnect the tool before changing discs. Do not force the disc into openings smaller than recommended clearance tolerances allow.
