New, “HSS drill with milling cutter cylindrical shank” SE high precision drill series

January 23, 2014
SE PDM

In the manufacturing field of such as aircraft, medical equipment and auto parts, demands for high-mix low-volume production, fast delivery and cost reduction have been increased at all times. HSS drills are therefore required as follows: which are 1) versatility to be suitable for a wide range of work materials, 2) stability that sudden trouble does not occur, 3) economic efficiency which can reduce the production costs.
HSS drill with milling cutter cylindrical shank, SE high precision drill series adopted D-STH surface treatment optimized for a drill which has been in a great demand for precision tool such as a shaving cutter and a broach. This provides lower cost and ensures less burrs and high precision drilling for coated HSS drill.

Features of HSS drill with milling cutter cylindrical shank, SE high precision drill series

1.
Good balance of cutting edge sharpness and excellent wear resistance by D-STH surface treatment with the deep harden layer to cover the wear area on the cutting edge.
2.
High precision diameter compared to coated HSS drill.
3.
Sharp cutting action and prevention of burr formation.
4.
Improved adhesion resistance and smooth chip discharge due to good surface texture compared to coated drill.
5.
Production costs can be reduced by decreasing tools cost by 10 to 40% compared to our coated drill.
