Century Drill Tool 75405 Cone Rotary File 1/2x7/8 Inch

Product Description

The CENTURY DRILL TOOL CO INC 75405 is a cone-shaped rotary file designed for rasping and filing soft metals. Built from special alloy steel that has been hardened and tempered, this rotary file delivers long service life and increased durability under repeated use. The precision cutting edges are engineered to resist clogging and loading, keeping the tool cutting cleanly throughout the job. The 1/4-inch shank is compatible with standard drill chucks across all common drill types, making it a straightforward addition to any tool kit. Sold in a package of 3 units, it suits tradespeople who need a reliable supply on hand for repetitive deburring, shaping, or finishing work on soft metal components.

This rotary file is suited for use on soft metals including aluminum, copper, brass, and similar non-ferrous materials. Typical applications include deburring pipe ends, shaping metal fittings, enlarging or cleaning up holes, and smoothing rough edges on sheet metal or cast components. The cone geometry allows the tool to reach into angled openings, inside tapers, and confined areas where flat or cylindrical files cannot easily access. Plumbers, HVAC technicians, and general tradespeople who work with soft metal fittings and components will find this format useful in both shop and field settings.

Installation Notes

Install the 1/4-inch shank securely into the drill chuck and tighten before operation. Always wear appropriate eye protection when using rotary files, as metal particles and chips are ejected during cutting. Operate at a speed appropriate for the material being worked to avoid heat buildup and premature wear of the cutting edges. This tool is intended for soft metals only and should not be used on hardened steel or masonry.
