Steel tooth bits series

114-117

Soft Formation Tooth Bits

The114-117 bits are used to drill low-compressive strength, soft formations.Long projection tooth lengths are used on high offset cones to provide the greatest penetration rates possible .Wear-resistant hard facing is used to control tooth wear .On the softest bit types this hard facing completely covers the bit teeth .

127

Medium-Hard Formation Tooth Bits

The127 bits are used to drill high-compressive strength,medium hard formations.Short projection teeth with reduced crest length are used in this series of bit designs .Durable hard facing is applied to reduce tooth wear.
