High Precision 5 XD Tungsten Carbide Drill Bits Inner Coolant With Brazer Coating

Solid carbide internal cooling drill bit is a hole processing tool. It has two spiral internal holes rotating from the shank to the cutting edge.

When Compressing the passing-through air, oil or cutting fluid during the cutting process, it can cool the tool and wash the chips away, reduce the cutting temperature and increase the service life of the tool.

With the Nano Blue coating on the surface, it also increases the durability of the drill bit and the stability of the processing size.

So the solid carbide internal cooling drill bits have better cutting performance than ordinary cemented carbide drill bits, especially suitable for deep hole machining and difficult-to-machine materials.

Specificaions:
Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems.

Suitable for carbon steel, chilled cast iron, ductile iron, gray cast iron, die steel, stainless steel, heat resistant alloy steel, tool steel.

Round shanks allow use with a wide variety of toolholding systems.

When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging.

Drilling, or hole making, is the most common metalworking operation in the world. Twist drill bits are the most common type of drill bit used. Twist drill bits are commonly used to drill holes with hand-operated drills, standalone drill presses, or lathes. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole.
