About this product
This Faithfull triangular engineers' file has three flat sides, making it suited to filing acute internal angles, cleaning up cut square corners, enlarging angular holes and sharpening serrated jaws and saw teeth. The 150mm (6in) length gives good control for detailed, precision work in confined spaces. It has a second cut (medium) grade, offering effective material removal while leaving a reasonable finish, and is fitted with a comfortable grip for extended use. Blade width is 13mm (1/2in). Aimed at professional tradespeople and regular DIY users, it is supplied as a single file.
