3M 7010327470 Straight Cartridge Roll 40 Grit Aluminum Oxide

Product Description

The 3M 7010327470 is a straight cartridge roll designed for precision grinding, deburring, and surface blending on metal and other hard materials. Built with aluminum oxide abrasive on a cloth backing, it delivers consistent stock removal at 40 grit — a coarse grade suited for aggressive material removal in tight bores, tubes, and contoured surfaces. At 0.75 inches in diameter, it mounts to a mandrel and is driven by die grinders or drill presses. This roll is a standard tool in metal fabrication, aerospace finishing, and general maintenance shops where controlled inside-diameter work is required.

This cartridge roll is used in applications requiring abrasive work inside bores, ports, holes, and other confined geometries. The coarse 40 grit rating makes it appropriate for initial material removal passes before progressing to finer grits. Typical use cases include weld cleanup, rust removal, and blending transitions in metal pipe, tubing, and castings. It is commonly used by machinists, fabricators, and maintenance technicians working on both ferrous and non-ferrous metals.

Key Features

• Aluminum oxide abrasive for durable, consistent cutting action on metal surfaces
• Coarse 40 grit rating suited for aggressive initial stock removal
• Cloth backing provides flexibility and conformability in contoured or curved surfaces
• 0.75 inch diameter fits standard cartridge roll mandrels for die grinders and drill presses
• Rated to a maximum of 16,000 RPM for safe operation at high speeds

Compatibility

Designed as an OEM-style replacement or standard consumable for use with cartridge roll mandrels compatible with 0.75 inch diameter straight cartridge rolls in die grinders and drill press setups.

Installation Notes

Installation is performed by machinists or maintenance technicians using appropriate mandrel hardware. Ensure the mandrel size matches the cartridge roll core before mounting. Always confirm the tool RPM does not exceed the 16,000 RPM maximum rating of this roll before operation. Inspect the roll for wear or separation before each use and replace if the abrasive or cloth backing shows signs of degradation.
