Benefits and features
From the shank to the cutting edge there are 2 spiral holes rotating according to the twist drill guide, which are passed through by compressed air, oil or cutting fluid during the cutting process and serve to cool the tool.
In addition to the cooling effect, it also flushes away the chips, reduces the cutting temperature of the tool and increases the life of the tool.
In addition to the TISIN coating on the surface of the internal cooling coated drill bit, it increases the durability of the drill bit and the stability of the machined dimensions, so this carbide coated internal cooling drill bit has more excellent cutting performance than the ordinary carbide drill bit, especially suitable for deep hole machining and difficult to machine materials. The drill bit with internal cooling hole is designed to reduce the damage to the drill bit and product appearance caused by high heat when the drill bit is processed at high speed, and the drill bit with double cooling hole effectively solves this problem.
Suitable for material range
Common steel, cast iron, chilled cast iron, forgeable cast iron, cast steel, alloy steel, tool steel, die steel and other materials
