Merit Abrasives OLD08834181745 Cartridge Roll 80 Grit

Product Description

The MERIT ABRASIVES OLD08834181745 is a full taper cartridge roll designed for precision deburring, blending, and finishing work on metal and other hard surfaces. Built with aluminum oxide abrasive at 80 grit, this roll delivers medium-grade cutting action suitable for controlled material removal and surface prep. The maximum roll diameter is 0.5 inches, making it well-suited for tight-access grinding in die grinders, straight grinders, and mandrel-mounted tooling setups. It is a single-piece unit and is commonly specified by machinists, toolroom technicians, and fabricators who need consistent, repeatable abrasive performance in confined areas.

Full taper cartridge rolls are used across metal fabrication, weld blending, and finishing operations where a tapered profile allows the roll to reach into holes, slots, ports, and contoured surfaces that flat or straight abrasives cannot access. The 80 grit aluminum oxide construction suits general-purpose stock removal and intermediate finishing passes on ferrous and non-ferrous metals. This roll is appropriate for shop environments including job shops, production lines, and maintenance repair operations requiring fine-detail abrasive work.

Key Features

• Full taper profile for access into recesses, ports, and contoured geometries
• 80 grit aluminum oxide abrasive for medium-grade cutting and surface preparation
• Maximum roll diameter of 0.5 inches fits standard mandrel tooling
• Single-unit package quantity with minimum order quantity of 100 units
• Lightweight at 0.01 pounds per unit for minimal added mass on tooling

Compatibility

Designed as an OEM-style replacement and standard consumable for die grinders and mandrel-mounted rotary tooling that accept 0.5-inch maximum diameter taper cartridge rolls.

Installation Notes

Cartridge rolls are installed by a qualified machinist or toolroom technician onto a compatible mandrel sized to the roll bore before mounting in the rotary tool. Ensure the grinder is fully powered down and unplugged before changing abrasive accessories. Verify mandrel RPM rating matches or exceeds the tool spindle speed before operation. Inspect the roll for damage before each use and do not force the roll onto an oversized mandrel.
