Diamond drill bit 6 wings Matrix body oil pdc core bit

Coring PDC bits drilling 
Introduction: 
PDC(polycrystalline diamond compact) drill bit is a new product after the hot-pressed and electroplated drill bits in recent years, with special high-frequency welding technology, . PDC of high wear resistant is welded to the body as cutting edges, PDC bit is mainly used for geological prospecting, coal exploration, water conservancy and power engineering etc. 
PDC Bits characteristics: 
1)Powdered metal matrix for longer service life. 
2) Advanced geometric design for faster penetration. 
3) Added cutters for maximum performance. 
4) TSP gauge protection. 
5) Large junk slots for better hole cleaning. 

PDC bit classification: 

1. Steel matrix bits: Fast speed, mainly used in soft rocks 
2. Hot-pressure sintering matrix bits: Good gauge protection, wear-resisting matrix, used in medium-hard rocks 
3. Non-pressure sintering matrix bits: Good gauge protection, better wear-resisting matrix, used in strong abrasive, hard rocks.
