Gunsmith's Premium Ceramic Stone File Set - Gunsmith's Premium Triangle Ceramic Stone

Flawless, man-made ceramic stones polish the surface of steel as they cut, so you save time as you produce a clean, ripple free surface on any metal with just a few easy strokes. Double, precision grinding after high pressure extrusion produces the consistent, extra-fine grit, true angles and the sharp, perfectly square edges necessary for top quality handgun and rifle trigger work. Extra hard ceramic material maintains its surface so edges stay square and straight without chips or glazing. Cuts can be made dry - so there's no messy cleanup - or with water. With normal care these high quality stones will maintain their edge and last a lifetime. Mfg: Brownells SPECS: Extra fine, white ceramic stones 3.50" (8.8cm) long.
