Product Description
Bit type | IADC Code | Applicable formation | Cutting structure | Normal WOB KN/mm(bit dia.) | Rotary Speed(rpm) |
THA217 | 217 | Medium hard with relatively higher compressive strength and hard stringers,such as hard shale,sandstone and limestone,etc. | Hardfaced gage and all tooth surfaces,and the gage fitted with compacts for enhanced gage protection | 0.50~1.20 | 100~50 |
Soft formation teeth bits:
The soft formations tooth bits are used to drill low compressive strength, soft formations. Long projection tooth lengths are used on high offset cones to provide the greatest penetrations rates possible. Wear resistance hard facing is used to control tooth wear. On the softest bit types this hard facing completely covers the bit teeth.
Medium hard formations tooth bits:
The medium hard formation tooth bits are used to drill high compressive strength, medium hard formations. Shoot projection teeth with reduced crest length are used in this series of bit designs. Durable hard facing is applied to reduce tooth wear.
