The E-Z Chamfer deburring tool, constructed from High Speed Steel (HSS), is designed to eliminate burrs and ridges from threaded rods, bolts, pipes, and bar stock. Its size range of 0.7” – 1.5” (18-38mm) allows efficient removal of threads and burrs, creating a smooth chamfer for effortless nut and die insertion. Compatible with mild, hard, very hard, stainless, and super hard steels, it delivers optimal results when used with slow drill speeds and moderate pressure on most materials. To extend the tool's lifespan, it's advisable to operate at speeds below 800RPM and refrain from using impact drivers. Typically, only 1-3 threads need chamfering for a clean start.

Additionally, E-Z Chamfer sizes between 18-24mm require a speed of 600RPM, those ranging from 23-29mm perform optimally at 400RPM, and sizes from 30-38mm are best suited for a speed of 300RPM.

Why a strut nut socket? To secure shocks and struts to their mounts, the retaining nut must be torqued to its proper specification using a torque wrench. Strut nut sockets allow for the use of a 21mm wrench to hold the damper shaft allowing you to achieve proper torque. An improper torque value may result in premature mount failure - or worse.
