Steel Tooth Drill Bits

1.ISO9001:2008 2.OEM Available 3.Suitable for medium to hard formation 4.High compressive strength

 Steel teeth bits series: 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.

 Product advantage:It is an ideal and economic tools for the high speed drilling drilling in low pressure . Structure features:

1.Rolling seal bearing structure, cylindrical roller cone in slots in the body, increasing the shaft neck size.2.Thrust bearing vice respectively by grinding surface treatment and hardening process.3.The differential pressure and prevent drilling fluid restrictions in the lubricating system all rubber oil storage sac,   and it provides  good lubrication guarantee for bearing system.4.Steel ball lock die, suitable for the high speed.5.The 250 ° C high temperature resistance, abrasion resistance of new grease.
