Aluminum Oxide Lapping Compound – 800 Grit | Final Fitting

Aluminum Oxide Lapping Compound – 800 Grit

The TMC Aluminum Oxide Lapping Compound – 800 Grit provides refined, controlled cutting for precision final fitting. When you need an ultra-smooth, silk-like finish, this compound removes material evenly while preserving tight tolerances. As a result, mating surfaces feel smoother, operate cleaner, and maintain proper alignment.

Gunsmiths choose aluminum oxide for finishing because it cuts predictably without damaging critical surfaces. Therefore, this compound works perfectly for slide-to-frame fitting on pistols as well as for fine tuning rifle bolt lugs and locking surfaces.

Perfect for Final Finish Work

The 800-grit abrasive excels during the final stages of fitting. For example, it smooths slide-to-frame contact on pistols and refines engagement between rifle bolt lugs and locking lugs. In addition, it helps create a glass-like finish between rifle bolts and raceways, improving cycling and overall feel.

Because aluminum oxide cuts cleanly and consistently, you maintain full control, even on close-tolerance parts.

Non-Embedding, Easy-Cleanup Formula

TMC suspends smooth, rounded aluminum oxide crystals in a durable synthetic and petroleum-based carrier. Unlike sharp abrasives, these rounded crystals do not embed into metal surfaces. Because of this, the compound stops cutting once you clean the part, preventing unwanted wear after fitting.

At the same time, the paste cleans up easily with soap and water. As an added benefit, the petroleum base protects carbon steel parts and helps prevent corrosion during use.

Long-Lasting and Shop Ready

Each container includes 2 ounces of lapping compound, providing enough material to last for years of precision fitting work. Whether you work in a professional shop or at a home bench, this compound delivers consistent, repeatable results.
