Norton Crystolon Square Abrasive Files are fast-acting silicon carbide products that are designed for use where moderate tolerances are acceptable, and speed of sharpening is more important than fineness.
Square Abrasive File applications range from dimensioning key-ways to maintain fit, stoning faces on router bits, touching-up edges of reamer teeth, and lapping/honing to close tolerances to produce the finest edge on precision instruments, die work, and delicate tools.
Norton abrasive files hold their shape while imparting the finest, most uniform finish on precision machine parts and in tool and die making. Abrasive files are ideal for any deburring, chamfering or radiusing job, or for filing delicate parts. Select the file shape that matches the contour of the surface being stoned.
