CTA Manufacturing Corp. released the E-Z CHAMFER, No. 3838. The E-Z CHAMFER is designed for removing burrs and ridges from bolts, pipe, threaded rod, bar, and dowels. Threads and burrs are sheared off to create a chamfer for starting a nut or threading die. The Chamfer tool is constructed of M2-HSS-High Speed Steel (tungsten-molybdenum high speed steel) with a well-balanced composition suitable for a wide variety of applications.
The E-Z CHAMFER is designed for use on the following materials:
Mild steel: U.S. Grade 2 – Metric Grade 4.8
Hard steel: U.S. Grade 5 – Metric Grade 8.8
Very hard steel: U.S. Grade 8 – Metric Grade 10.9
Stainless steel: 300 Series
Super hard steel: U.S. Grade ASTM-A574 – Metric Grade 12.9
For best results, CTA suggests technicians use a slow drill speed (maximum 800 rpm) with medium pressure on most materials. Harder materials will require a higher feed pressure.
