12" THREE SQUARE FILE

Professional triangular machinist file is a high-performance tool designed for precision work and material removal on angular profiles. It is widely used in machine shops, metalworking, and general industrial applications.

Manufactured from forged high-chromium steel and subjected to a double heat-treatment process to provide maximum wear resistance. Its double-cut pattern and teeth on all three faces ensure a high material removal rate and a uniform finish. It is ideal for roughing, fitting, deburring, and finishing angular profiles in machine shops and industrial environments.
