The PFERD 15816242 is a 5-piece diamond file set designed for precision material removal and finishing on hard materials including hardened steel, carbide, ceramics, glass, and non-ferrous metals. The set includes five file shapes — Crossing Oval, Hand Flat, Round, Square, and Three Square — each with a medium-grade diamond abrasive surface and a 1-inch (25.4 mm) length of cut. Diamond files deliver consistent cutting action on materials that conventional files cannot effectively work. The set stores in an included plastic box for organized transport and tool protection on the job site.
This file set is suited for trade professionals and skilled technicians who require precise deburring, shaping, and finishing in tight tolerances. Typical applications include deburring valve seats, fitting keyways, dressing carbide tooling, and shaping hard plastics or composites. The variety of file profiles — flat, round, square, and triangular cross-sections — covers the most common filing geometries encountered in mechanical, tool and die, and maintenance work. The compact cut length makes these files effective in restricted access areas where full-size files cannot reach.
Designed as a general-purpose diamond file set suitable for use on hardened steel, carbide, ceramics, glass, stone, and non-ferrous metals where conventional file cutting is ineffective.
Diamond files are hand tools requiring no power source or fastened installation. Secure the workpiece before filing to prevent movement and injury. Files without built-in handles should be fitted with an appropriate handle before use to reduce the risk of hand injury from the tang. Inspect the diamond surface before each use and replace files that show worn or damaged abrasive areas to maintain accurate material removal.
