4004 FILE

12" ROUND FILE SMOOTH

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

Removes the marks left by coarser-cut files.
Enables precise adjustments and delivers higher-quality finishes.
Greater precision and improved surface quality during roughing operations.
Allows parts to be brought to their final dimensions with a high level of control.
