4 1/2inch PDC Core Drill Bit 8 Blades Exploitation Bit For Mining
Characteristics:
1. The structure of the core drill bit is simple, and the cutting track is single in the underground.It is easy to be saltatory during the drilling. The high impact-resistance cutters (model 1308) are making sure stablize the bit.
2. We adopt five-axis high-precision process technology to design the noumenon of the core drill bit, so the tooth hole of the bit is in a high precision, and the bit is more stable during the drilling.
3. We use gauge strip to strenghthen the integral structure of the bit, and we also increase the impact resistance of the bit. So the cutters have good fluctuation stability with high rock-breaking efficiency during the rock breaking.
