3M 7010328349 Cartridge Roll Mandrel 3/32x3/4x1/4 in

Product Description

The 3M 7010328349 is a screw-type cartridge roll mandrel designed to securely drive cartridge rolls during grinding, deburring, and finishing operations. The mandrel measures 3/32 inches pilot diameter, 3/4 inches pilot length, and 1/4 inches shaft diameter. These three dimensions correspond to pilot diameter, pilot length, and shaft diameter respectively. The screw-type locking mechanism holds the cartridge roll firmly in place under load, reducing slippage and maintaining consistent contact with the workpiece. Metalworkers, fabricators, and industrial maintenance technicians use this mandrel with rotary tools, die grinders, and similar power equipment to perform precision abrasive work.

This mandrel is suited for use in metal fabrication shops, manufacturing environments, and maintenance repair operations where cartridge rolls are used for internal diameter finishing, port blending, weld cleanup, and edge deburring. It is compatible with 1/4-inch collet die grinders and similar rotary tools that accept a 1/4-inch shank. The compact 3/32-inch pilot diameter makes it appropriate for small-bore and tight-clearance applications where a standard mandrel would not fit.

Key Features

• Screw-type locking mechanism holds cartridge rolls securely under rotational load
• Pilot diameter of 3/32 inches suits small-bore and tight-clearance grinding applications
• 1/4-inch shaft diameter fits standard die grinder collets
• 3/4-inch pilot length provides stable roll support during use
• Lightweight at 0.04 pounds, adding minimal weight to the tool setup

Compatibility

Designed for use with cartridge rolls that match a 3/32-inch pilot diameter bore, intended for use in 1/4-inch collet die grinders and rotary tools accepting a 1/4-inch shank mandrel.

Installation Notes

Installation is performed by threading the appropriate cartridge roll onto the screw-type pilot until fully seated and snug. Ensure the die grinder or rotary tool is powered off and disconnected from any air or electrical supply before changing mandrels or cartridge rolls. Verify the 1/4-inch shank is properly seated and tightened in the collet before operation. Follow the tool and abrasive manufacturers guidelines for maximum RPM compatibility between the mandrel, cartridge roll, and drive tool.
