Quick details of drilling bit

 

All thread bits are available in various flushing hole configuration. In general, the rule is that Semi-spherical type bit design are applied to very hard rock. Ballistic type to medium hard and Conical type to soft rocks.

 

 

 

Bit design	Brief Introduction
Drop center	Perfect in abrasive formations where there is accelerated button wear or in medium to hard rock when ballistic buttons have tendency to break.
Drop center/retrac	To be used in medium-hard and fissured rock formations, better hole deviation control.
Flat front	Ideal for medium hard rock when the rock formation causes heavy gauge wear on the bit. Can also used in very hard and abrasive rock formations.
