External deburr/chamfer tool fitted with HSS blade for repairing damaged bolts. Effective on Stainless Steel, hardened steel, mild steel, copper, brass, wood, fibreglass, hard plastic.> Size range 3 - 19mm> Speed 0 - 400rpm> High Speed Steel blade 1/4"" shankIn a busy workshop there are numerous instances of threads getting damaged: whacking a track rod end with a hammer; cutting a bolt or threaded rod - the threaded ends get torn and squashed. Wheel studs get damaged just by removing and refitting the wheels¦ Luckily there is a quick and easy solution - the external deburr & chamfer tool.The chamfer tool is designed to be used with an electric drill and is fitted with a 1/4"" quick-chuck shaft, maximum recommended speed is 400rpm. The tool is fitted with three super-hard High Speed Steel blades that make light work of repairing damaged bolts and damaged threads. The blades cut quickly and cleanly and are effective on stainless steel, hardened steel, mild steel, copper, brass, wood, fibreglass, and even hard plastic. Bolts, studs and threaded rod, size range from 3mm right up to 19mm. Hammer-damage or squashed and flattened threads will stop the retaining nut or wheel nut screwing back on; a couple of zaps from the deburr/chamfer tool solves the problem instantly. Cutting steel or copper pipe can leave an uneven edge that can stop an olive or tube nut being slid on. A gentle touch with the tool leaves a nicely chamfered edge, and the olive slides straight on.
