Overview

This abrasive compound is intended for hard fitting two pieces of steel, especially when working with hardened and heat-treated steel. Its silicon carbide grit is paired with a thick petroleum-based lubricant that is designed to keep the compound working as the particles break down during use. It is made for steel only and should be removed with solvent after use. The 4 fl. oz. package is a practical size for shop work where controlled fitting is the goal.

Pros

  • Sharp-edged silicon carbide compound designed for hard fitting two pieces of steel
  • Thick, long-lasting lubricant helps the compound continue cutting during extended fitting
  • Breaks down into smaller sharp-edged particles to maintain cutting action longer
  • Suitable for continued fitting on hardened and heat-treated steel
  • 4 fl. oz. container provides a practical amount for shop use
  • For use on steel only, with solvent cleanup after use

Considerations & Trade-offs

  • Designed for steel fitting work only, so it is not intended for use on other materials.
  • The petroleum-based lubricant means cleanup is required after use; the product must be removed with solvent.
  • As a #120 grit compound, it is suited to abrasive fitting and polishing work at that grade rather than finer finishing tasks.
  • The compound is formulated to keep cutting during continued fitting, which implies it is meant for controlled material removal rather than light touch-up work.
