OVLIN TCT Insert Carbide Tungsten Steel Milling Cutter Countersink 60/90 Degree Inner Hole Deburring Welding Chamfering Cutter (Hole Diameter : 20mm-90degree)

-In order to ensure the firmness of the drill bit, we adopted a brazing method to weld carbide inserts. -In this way, the drill bit can process harder metal (compared with HSS countersinks).But this will make the appearance of the drill bit not good-looking. -Because the cutting edge of carbide material is very crisp, them machining environment needs to be stable to reduce beating. -It performs well when machining Non-ferrous metals, cast iron, General steel, alloy steel, etc. -Suitable for low rotating speed and low cutting allowance.
