Tungsten carbide spiral flute step drill bit set

Tungsten carbide spiral flute step drill bit set

Carbide step drills are also called step drills or pagoda drills. They are mainly used for drilling thin steel sheets within 3mm. One drill bit can be used instead of multiple drills. Different diameter holes can be machined according to needs, and large holes can be realized. One-time processing is completed, no need to change the drill bit and position the positioning hole.

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.
