Product Description

External cold alloy twist drill Carbide Twist Drills

They are suitable for drilling steels and cast iron and are available in stub (3xD) or jobber (5xD) maximum drill depth. The perfect partner for high productivity drilling.

Cemented carbide has a series of excellent properties such as high hardness, wear resistance, strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which
remains basically unchanged even at a temperature of 500 ° C. At 1000 ° C, there is still a high hardness. In the aspect of cast iron processing, our reamer can process the smoothness of the hole to less than 0.4;
Scope of application: The reamer has multiple cutter machining characteristics, which are used to ream the drilled (or reamed) hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce the
surface roughness. In the finishing of the hole, the semi-finished tool has a small machining allowance. Because the reamer has the blunt radius of the cutting edge, it has a wiper blade, and the flank has a 0.03~0.05mm edge.
Therefore, the pressing action is large, so the reaming process is actually the result of both cutting and squeezing.
