The CTA Manufacturing E-Z Chamfer Tool, No. 3838, is designed for quick and clean deburring. The key feature is a 5-point cutting design to efficiently remove burrs and ridges from bolts, pipes, threaded rods, wheel studs, bars, and dowels, creating the ideal chamfer for starting a nut or threading die, says the company. The single-piece, tungsten-molybdenum HSS construction, provides durability and accuracy.
