Merit Abrasives OLD08834181747 Cartridge Roll 120 Grit

Product Description

The MERIT ABRASIVES OLD08834181747 is a full taper cartridge roll designed for precision deburring, blending, and surface finishing in tight contours, bores, and hard-to-reach areas. The roll is constructed with aluminum oxide abrasive at 120 grit, placing it in the fine grade range. Full taper geometry allows the roll to conform to irregular surfaces and provides consistent stock removal along the entire working length. At a maximum diameter of 0.5 inches, this cartridge roll is well suited for use in rotary die grinders and mandrel-mounted setups common in metal fabrication and finishing shops.

This cartridge roll is used in metalworking applications where a fine finish is required after rough grinding or machining. Typical scenarios include blending welds, smoothing inside radii, and finishing bore surfaces on ferrous and non-ferrous metals. The aluminum oxide abrasive provides reliable cut rate and durability across mild steel, stainless steel, aluminum, and similar materials. It is appropriate for both production and maintenance environments where consistent surface prep results are needed.

Key Features

• Full taper profile conforms to contours and inside surfaces for even abrasive contact
• 120 grit aluminum oxide abrasive delivers fine-grade material removal and surface blending
• Maximum roll diameter of 0.5 inches fits standard mandrel and die grinder setups
• Aluminum oxide construction provides consistent cut rate on ferrous and non-ferrous metals
• Sold individually; minimum order quantity of 100 units supports production-level stocking

Compatibility

Designed for use with standard mandrel-mounted rotary die grinders and finishing tools that accept full taper cartridge rolls up to 0.5 inches maximum diameter.

Installation Notes

Cartridge rolls are installed by a machinist or metal finishing technician onto a compatible mandrel sized to the roll bore diameter. Ensure the grinder or rotary tool is powered down and unplugged before mounting or removing the roll. Verify mandrel thread and shank size match the tool collet before use. Do not exceed the maximum RPM rating of the cartridge roll for the tool being used.
