External Chamfer Deburring Tool 3-19mm 1/4in Hex

A chamfer deburring tool for cleaning up damaged threads, removing burrs and restoring the lead-in on bolts, studs and other threaded fasteners. Covering 3-19mm sizes, it cuts externally to help tidy rough or battered ends before refitting nuts.

Used for vehicle maintenance, workshop jobs, site repairs and general DIY work, this type of tool helps when bolt threads have been knocked, burred or slightly mushroomed during removal or handling. Rather than struggling with a file or replacing usable fixings straight away, it gives you a quicker way to repair damaged fasteners so nuts can start more cleanly. Handy for mechanics, fabricators, maintenance work and anyone dealing with stainless steel, mild steel, brass, copper or plastic fixings.

Fitted with 3 YG8 blades, the tool removes damaged metal from the outside edge of the thread to form a cleaner chamfer. The 1/4in hex shank allows use with a drill or hex driver, which makes it easier to work consistently on repeated jobs. Its 3-19mm range covers many common bolt and stud sizes, making it useful for regular maintenance without needing to switch to slower hand-finishing methods. It is also a practical option when you want a neater, more controlled result than using a file or angle grinder on smaller threaded parts.
