The description of  the steel tooth bit.

The steel tooth bits series: 

Soft formation steel tooth 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.

The characteristics of the steel  drill bits :

(1). It has rolling sealed bearing structure. The cylinder rolling element is placed within the groove 

of roller cone, thus enlarging the journal size and ensuring a better performance of roller bit.

(2). The secondary surface of thrust bearing of roller bit has been handled with antifriction and 

hardening treatment so as to decrease the frictional force of bit for protecting its hardening resistance.

(3). The roller bit uses new type lubricating grease which can bear the high temperature of 250ºC and boasts abrasion resistance. 

(4). The full rubber oil reservoir uses limitable differential pressure and can prevent drilling fluid 

from entering lubricating system so as to provide qualified lubrication for bearing system
