Halco DTH Bits

There are three different bit heads on offer, Convex, Flat Face and Concave, also with three different inserts that can tackle any challenge and rock face formation. The two most important factors in choosing the right drill bit are productivity and reliability. For soft to medium rock formations where penetration rates are high the ballistic and semi-ballistic inserts coupled with flat face or concave bit heads are more suitable. If the rock formation is on the hard to very hard side, it is more advisable to use a domed insert with convex head this will result in a longer drill bit life.


Features:

1. Using higher grade carbides for longer life;

2. Minimizes hole erosion in fragile formations

3. Diamond PDC buttons would be available by requests.

4. Drills faster through soft formations with less blockages

5. Drills straighter through consolidated and unconsolidated formations
