Water Well Button Drill Bit Hammer Drill Bit Set Carbon Steel
Material
Description
DTH (Down to Hole) drill bit, also called spline connected drill
bit, is mainly used in large scale mine
(open and underground), open quarry and construction. The hammer is
situated down the hole in direct
connected with the drill bit with splines in the bit. The hammer
piston strikes the drill bit resulting in an efficien
t transmission of the impact energy and insignificant power losses
with the hole depth.
The bits in the new range have an optimized head length with
maximized steel support for the cemented
carbide buttons, deep face grooves for excellent flushing and an
aggressive cutting structure.
Application
DTH drill bits range covers the most diverseapplications in mining,
natural resources exploration, water wells,
quarries and civil works.

Advantages:
1. Computer analysis and laboratory trials have been used to
optimize the number of buttons as well as their
size and positioning throughout the bit front.
2. Carbide has been carefully designed to minimize the risk of
button loss and button failure
3. The design of the bit body and the frontal sludge grooves
provides uniform flushing with reduces steel
wash on both bit and the hammer.
4. Material processes and multiple heat treatment have focussed on
achieving maximum resistance to fatigue failure.
5. Special bit designs such as Concave and Convex/CB are available
on request.
