250 mm Triangular Metal File

Put the right profile where it belongs. This 250 mm triangular file from Teng Tools delivers the pointed, three-sided cross-section that metalworkers and woodworkers reach for whenever a job demands filing into tight internal corners, angular slots, or V-grooves.

The bi-material handle pairs a rigid inner core with a softer exterior grip, so the tool stays planted in your hand stroke after stroke. Its ergonomic shape prevents rolling on the bench and gives you the tactile feedback you need to control cut depth and direction, whether you are dressing a machined keyway or fitting a timber joint.

At 250 mm long and 268 g, this is a full-size shop tool, not a miniature hobby accessory. The longer stroke bridges surface irregularities better than pocket-sized alternatives, producing flatter, more consistent results with fewer passes. That efficiency matters when you are standing at the bench all day working through a stack of parts.

Ideal for machinist tools collections, general fabrication, maintenance shops, and any trade where controlled material removal in confined geometry is part of the daily routine. Whether you are sharpening a tooth file profile on a hand saw, easing a hinge mortise, or prepping a weld joint, this triangular profile earns its place in the drawer.

Part of the Teng Tools professional system, this file is built to the same standard of fit and finish that professional mechanics and tradespeople expect from every tool in the lineup.
