Merit Abrasives 66261194133 Cartridge Roll 180 Grit

Product Description

The MERIT ABRASIVES 66261194133 is a full taper cartridge roll designed for precision deburring, blending, and surface finishing in tight contours, slots, and hard-to-reach areas. It features an aluminum oxide abrasive at 180 grit, placing it in the very fine grade range. The tapered profile allows the roll to conform to curved and irregular surfaces, making controlled material removal more consistent. At a maximum roll diameter of 3/8 inches, this cartridge roll is sized for small-bore and detail finishing work. It is used primarily by machinists, fabricators, and maintenance technicians working with ferrous and non-ferrous metals.

This cartridge roll is suited for rotary tool setups including die grinders and flexible-shaft machines used in metal fabrication, weld blending, and aerospace or automotive finishing applications. The very fine 180-grit aluminum oxide construction makes it appropriate for final-pass surface preparation, light stock removal, and scratch refinement before polishing. It is sold individually and is commonly ordered in volume for production or shop use.

Key Features

• Full taper profile conforms to contours, slots, and internal radii
• 180-grit aluminum oxide abrasive for very fine finishing and scratch refinement
• 3/8 inch maximum roll diameter for small-bore and detail work
• Compatible with standard mandrel-mounted die grinder and rotary tool setups
• Lightweight at 0.015 pounds for extended use without fatigue

Compatibility

Designed as an OEM-style replacement-compatible abrasive cartridge roll for use with standard tapered mandrels in die grinders and rotary finishing tools accepting 3/8 inch maximum diameter cartridge rolls.

Installation Notes

Installation is performed by machinists or fabricators using a compatible tapered mandrel secured in a die grinder or rotary tool. Ensure the mandrel is properly tightened and the tool is powered off before mounting or removing the cartridge roll. Operate within the RPM rating of the tool and abrasive to prevent roll failure. Eye protection and appropriate PPE should be worn during use per standard shop safety practice.
