Overview

KEYSTONE Knife-Edge Engine Stone Wheels are silicon-carbide bonded abrasive Wheels with a thin, Knife-Edge profile — designed for detail grinding in tight spaces where a standard mounted point would be too large. Useful for interproximal contouring, framework relief, narrow-radius details on partial-denture saddles, and any lab task where the work-area is too tight for a full-thickness wheel.

Color-coded by grit grade (Red, Green, etc) — match the color to the material being worked (see the color-coding family for mounted silicon-carbide stones in this catalog).

• Knife-Edge profile. Thin cutting edge for tight-area work — interproximal, narrow-radius details.
• 3/32" HP shank, pre-mounted.
• Silicon-carbide bond. Cuts at predictable rate without glazing.
• Color-coded by grit grade.
• Made by KEYSTONE Industries.
