Product Description

8-3/4inch 7 Blades Steel Body PDC Drill Bit Oil Gas Petroleum Drilling Tools



1. The crown surface of the bit is long cast surface which is suitable for neutral formation and abrasive formation.
2. The conical surface is shallow, so the bit has good cleaning power.
3. The angle of the PDC cutter is 13-16°,which makes the bit have stronger aggressivity and higher ratory speed.
4. The design of the spiral blades is good for PDC cutter exposure and makes the bit drill into deeper formation in a higher speed.
5. The design of the high blades and deep flow pass makes the rock powder expel from the pit bottom as soon as possible.It can prevent the bit from repeatedly cutting and balling.
6. The mid-length gauge surface is inset/inlaid by double-row PDC cutter gauge teeth so that the bit has high abrasive resistance and good gauge effect.
