Apex 21857LN Half Round File Bastard Cut 8 Inch

Product Description

The APEX 21857LN is a bastard-cut half round file designed for shaping, smoothing, and deburring metal, wood, and composite surfaces in trade and shop environments. The file measures 8 inches in working length with an overall length of 10.12 inches, a width of 0.75 inches, and a thickness of 0.20 inches. Constructed from steel with a hard-stamped marking style, this file delivers consistent cut performance across the working surface. The half round profile provides two distinct cutting faces in one tool: a flat face for broad stock removal and a curved face for concave contours and inside radii. It is sold individually without a handle.

This file is suited for general metalworking, pipefitting, HVAC fabrication, and maintenance tasks where material needs to be dressed, fitted, or deburred by hand. The bastard cut is a medium-coarse grade appropriate for moderate stock removal before finishing with a finer cut file. Technicians working on sheet metal edges, pipe ends, bracket fitment, or rough castings will find the bastard cut useful as a first-pass tool in a standard file progression.

Installation Notes

Hand files should be fitted with an appropriate handle before use to prevent injury from the tang. Always file with controlled forward strokes and lift on the return stroke to preserve the cut teeth. Secure the workpiece in a vise before filing. Inspect the file for cracks or damage before each use and replace if the cut surface is worn smooth.
