UniBurr Plus Deburring Tool - Proudly Made in the USA

The UniBurr Plus is a simple yet intelligently designed chamfer tool for repairing damaged fastener threads to prepare bolts and threaded rod to thread nuts. The compact size and design of the UniBurr simplifies the fastener repair process. The tool operates like a drill bit, with a compact design to be easily carried in a pocket or tool pouch. The UniBurr Plus chamfer tool is designed for use on sizes #8-32 (.164") through 3/4"-10 (0.75").

The UniBurr Plus is manufactured out of Tool Grade Steel with a 92 Rockwell Coating. This durable design makes the tool suitable for use on hard metals including stainless steel, hardened steel, mild steel, copper and brass, as well as wood, fiberglass and plastic. Besides durability, the design is also safety conscious to prevent sparks, burns or cut hands. Additionally, the tool does not over heat the work piece when used properly. Benefits also include the tools deburring method; Threads are sheared off, not folded over as would happen with a grinder.

This shearing method is the key aspect of the tool, but also creates an important practice: THE SLOWER THE BETTER. The tool is effective at speeds up to 600 RPMs. It is recommended that the tool be used in a hand drill at its slowest setting, with decent pressure applied to the tool. It is important to remove only the threads needed to allow an easy start for the nut. This will preserve the life of the UniBurr tool and keep the shearing edges working efficiently. There is no need to give a bolt thread a pencil-sharp tip!
