12" THREE SQUARE 2ND CUT

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.

FEATURES

Manufactured from high-chromium steel for enhanced strength and wear resistance.
Forged and double heat-treated to improve the steel structure and increase hardness.
Precision-ground file with teeth on all three faces to ensure uniform performance.
Uniform tooth geometry delivers smoother, more controlled, and consistent filing action.

BENEFITS

Provides an optimal balance between material removal rate and surface finish quality.
Produces a more uniform surface finish than a coarse-cut file.
Allows roughing and refining in a single operation.
Suitable for a wide range of metallic materials.
