7 1/2" DTH Hammer Bits 191mm SD6 DTH Bit Rock Drill Bits for
Waterwell Drilling
Description:The dth button bits are made of superior quality alloy steel which
is made by Timken in U.S. Besides, all our DTH bits are using the
brand "Element Six" T.C carbide which provides (the T.C buttons)
for Boart Longyear. In addition art manufacturing technology makes
our dth button bits with higher and more reliable quality.
Different face style makes DTH bits suitable for various rock
conditions.
Flat face: This is an universal design, especially for hard and abrasive
rock formation. So typically, flat face with hemi-spherical buttons
design is the most popular choice.
Convex face: A classic design for soft to medium hard rock formation which is
not so abrasive. This design have very excellent penetration rate
but poor in hole deviation if rocks are hard.
Concave face: Medium hard to hard rock formations which is less abrasive and
fractured. Especially for deep hole drilling, excellent control
over hole deviation.
DGR face: A special design for hard or very hard rock conditions, double
gauge row buttons provide very excellent ware-resistance and very
longer life time. It is usually used for some bigger diameter DTH
bits.
Besides, we are manufacturing the DTH bits with various shanks so
they can be compatible with different DTH hammers.
