Merit Abrasives 08834112056 Flap Wheel Refill 120 Grit

Product Description

The MERIT ABRASIVES 08834112056 is an aluminum oxide flap wheel refill designed for precision surface finishing and deburring on metal, wood, and composite materials. Rated at 120 grit in the fine grade range, this refill features a scored surface that promotes consistent abrasive contact and helps control heat buildup during use. The trim length measures 1-1/4 inches with a 1-inch width, making it a compact option suited to detail work and confined surface areas. Machinists, fabricators, and finishing technicians use flap wheel refills like this one with compatible mandrels on die grinders and drill presses to achieve smooth, controlled stock removal.

This flap wheel refill is suited for fine finishing passes on metal components, tubing, and pipe ends where surface prep or light deburring is required. The scored surface pattern improves conformability to contoured and irregular workpieces. At 120 grit, it is appropriate for final-stage finishing after coarser material removal has already been completed. It is commonly used in light fabrication shops, maintenance environments, and production finishing lines where consistent fine-grade results are needed across repeated operations.

Key Features

• 120 grit aluminum oxide abrasive for fine-grade surface finishing
• Scored surface type promotes uniform abrasive contact and reduces heat buildup
• 1-1/4 inch trim length by 1 inch width for detail and confined-area work
• Refill format compatible with standard flap wheel mandrels
• Fine grade designation suitable for final finishing passes after coarse stock removal

Compatibility

Designed as a replacement flap wheel refill for use with compatible mandrels on die grinders and rotary tools that accept 1-1/4 inch trim length by 1 inch wide flap wheel refill inserts.

Installation Notes

Installation is performed by fabricators or finishing technicians. Ensure the rotary tool or die grinder is fully powered off and unplugged before mounting the refill onto the mandrel. Confirm the mandrel arbor size and refill dimensions match before securing. Always verify the tool RPM rating does not exceed the abrasive wheel rating before operation.
