Drop center face

For high penetration ratesin soft to medium-hard and fissured rock formations. Low to medium airpressures. Maximum hole deviation control.

bit face-2.jpg Concave face

The all-round applicationbit face specifically for medium hard and homogeneous rock formations. Goodhole deviation control and good flushing capacity.

Convex face

For high penetration ratesin soft to medium-hard with low to medium air pressures. It is the mostresistance to steel wash, and may reduce the load and wear on the gaugebuttons, but poor hole deviation control.

bit face-4.jpg Flat face

This kind of face shape issuitable for hard to very hard and abrasive rock formations in applicationswith high air pressures. Good penetration rates an resistance to steel wash.

Double gauge face

This kind of face shape issuitable for fast penetration rates in medium to hard rock formations. Designedfor high air pressures and good resistance to steel wash step gauge bit.
