Coating :All end mill set with Balzers PVD Coating,it is excellent resistance .
Design: High Helix Angle 50°,Six cutting edges reduce cutting load of each edge, decrease cutting volume, with high RPM, Can achieve smoother cutting surface.
Material:HRC68 ultrafine grain tungsten carbide, toughness and hardness and wear resistance. Manufacturing:Five-axis high precision grinding machine, keep the carbide router bits Stable and controllable.
Quality Control:Each milling bit will be tested on the detecting instrument and laser a code. Application:The cnc mill set is greatly performance for finish machining.
Inch Size and Diameter Tolerance:Diameter 1/2 - Cutting Edge Length 1.25" - Overall Length 3" Tolerance:-0.00mm to -0.01mm.
