Century Drill Tool 75408 Domed Cylinder Rotary File

Product Description

The CENTURY DRILL TOOL CO INC 75408 is a domed cylinder rotary file designed for rasping and filing soft metals. The body is machined from special alloy steel that is hardened and tempered for extended service life and increased durability. Precision-ground cutting edges resist clogging and loading during use, maintaining consistent material removal throughout the job. The 1/4-inch shank is compatible with standard drill chucks, making this file a practical addition to any trade toolkit where controlled stock removal on soft metal is required.

This rotary file is suited for shaping, deburring, and finishing cuts in soft metals such as aluminum, copper, brass, and similar materials. It is commonly used by HVAC technicians, plumbers, and general tradespeople during fabrication, repair, or rough finishing tasks. The domed cylinder profile allows access to contoured surfaces and inside radii where flat files cannot reach effectively. It mounts directly to any standard drill or rotary tool with a 1/4-inch chuck.

Installation Notes

Secure the 1/4-inch shank fully into the drill chuck before operation and confirm the chuck is tightened properly. Always wear eye protection when operating rotary files, as material chips can be ejected during cutting. Do not use this file on hardened steel or masonry, as it is rated for soft metals only. Operate at speeds appropriate for the material and file diameter to avoid premature wear.
