Merit Abrasives 08834180079 Cartridge Roll 50 Grit 1/4 in

Product Description

The MERIT ABRASIVES 08834180079 is a straight cartridge roll designed for precision grinding, deburring, and surface finishing in tight spaces and contoured areas. Constructed with aluminum oxide abrasive, this roll delivers consistent stock removal at 50 grit, placing it in the coarse grade range suited for aggressive material removal on ferrous and non-ferrous metals. At 1/4 inch in diameter, it fits standard mandrel-mounted die grinders and pneumatic rotary tools commonly used in fabrication, maintenance, and repair environments. Metalworkers, machinists, and maintenance technicians reach for this type of roll when working ports, bores, slots, and internal radii where flat abrasives cannot reach.

This cartridge roll is well suited for weld blending, rust removal, and edge conditioning on steel, aluminum, and similar materials. The straight profile maintains consistent contact in cylindrical and near-cylindrical applications. Its 1/4 inch diameter makes it appropriate for small-bore finishing operations and tight-clearance deburring tasks common in machine shops, HVAC equipment fabrication, and general metal maintenance. The coarse 50 grit formulation is particularly effective where rapid material removal is the priority before stepping down to finer grits for finish work.

Key Features

• Aluminum oxide abrasive construction for consistent cutting action on metal surfaces
• 50 grit coarse grade for aggressive stock removal and weld blending
• 1/4 inch diameter straight profile for access to bores, ports, and tight internal contours
• Designed for use with mandrel-mounted die grinders and pneumatic rotary tools
• Sold individually; minimum order quantity is 100 units per order

Compatibility

Designed as an OEM-style consumable replacement for 1/4 inch diameter straight cartridge roll mandrels used in standard die grinders and rotary tool setups common in metalworking and maintenance applications.

Installation Notes

Installation is performed by a machinist or maintenance technician using a compatible 1/4 inch cartridge roll mandrel threaded into a die grinder or pneumatic rotary tool. Always confirm the mandrel diameter matches the roll bore before mounting, and ensure the tool is powered off and depressurized before changing abrasives. Eye protection and appropriate respiratory protection should be worn during use. Do not exceed the maximum RPM rating of the mandrel or tool being used.
