4004 FILE

12" ROUND FILE BASTARD

The round machinist's file is designed for roughing, fitting, shaping, and finishing curved or internal surfaces on metal parts and other materials. Its cylindrical shape allows it to reach areas where a flat file cannot. It is ideal for shaping, fitting, deburring, and finishing holes, radii, and internal surfaces with precision.

Ideal for working on steel, stainless steel, iron, cast iron, aluminum, copper, brass, and bronze, especially for roughing, fitting, deburring, and finishing operations on holes, radii, and internal surfaces.

FEATURES

  • Manufactured from high-chromium steel and subjected to a dual heat-treatment process.

  • Precision-ground blade with double-cut teeth and a uniform tooth pattern on all four sides.

  • Compatible with an ergonomic bi-material handle that enhances grip and helps reduce vibration during use.

BENEFITS

  • Helps reduce visible filing marks.

  • Ideal cut for achieving smooth and uniform surfaces.

  • Removes small amounts of material in a controlled manner.

  • Minimizes the risk of removing more material than required.
