3M 7010327684 Full Taper Cartridge Roll 3/4 in 120 Grit

Product Description

The 3M 7010327684 is a full taper cartridge roll designed for precision grinding, deburring, and blending on metal, wood, and composite surfaces. Built on a heavyweight X-weight cloth backing, this roll delivers consistent cut and durability under high-pressure rotary tool applications. The aluminum oxide abrasive grain runs at 120 grit, placing it in the fine grade range — suited for finishing passes and light material removal where surface quality matters. The maximum roll diameter is 3/4 inch. Machinists, fabricators, and metal finishing technicians typically mount these rolls on mandrels fitted to die grinders or drill presses.

Full taper cartridge rolls like the 7010327684 are used in tight-radius interior surfaces, contoured slots, and hard-to-reach areas that flat abrasive media cannot access. Common applications include weld seam blending, port work, and bore finishing in metal fabrication and production environments. The fine 120-grit aluminum oxide construction makes this roll appropriate for intermediate to final finishing stages rather than aggressive stock removal.

Key Features

• 120 grit aluminum oxide abrasive for fine-grade finishing and controlled material removal
• X-weight cloth backing provides high tensile strength and resistance to tearing under rotary load
• Full taper geometry allows access to contoured surfaces, slots, and internal radii
• 3/4 inch maximum roll diameter fits standard cartridge roll mandrels
• Sold individually per package; minimum order quantity is 100 units

Compatibility

Designed for use with standard cartridge roll mandrels in die grinders, drill presses, and flexible shaft machines that accept full taper cartridge rolls up to 3/4 inch diameter.

Installation Notes

Installation is performed by threading the roll onto a compatible tapered mandrel and tightening per the mandrel manufacturer's guidance — do not over-tighten, as this can distort the roll core. Confirm the tool RPM rating meets or exceeds the abrasive roll's rated maximum speed before operation. Wear appropriate eye protection and gloves when mounting or operating cartridge rolls. Inspect the roll for fraying or core damage before each use and replace if wear is uneven or the backing shows separation.
