140mm QL50 DTH hammer Drill bit ore mining hole drill bit for
mining
DTH Button Bits
DTH drilling is a percussion system driving a piston inside hammer
body with up and down motion by compressed air and transmitting an
intensive percussion energy to the bit to enable the drilling by
crushing the rock. Drilling method by DTH hammer exerts high
drilling performance especially for drilling hard rock and
contributes for shortening work schedule. Hence, this method is
widely utilized for foundation work, landslide prevention work,
quarrying services, marine civil work, etc.
KSQ makes and supplies the finest and most efficient Down-the-Hole
(DTH) hammers and bits for the mining, construction and water well
industries. Sansung DTH hammers transmit intensive impact energy
with low energy loss. This results in good rock breakage, high
penetration rates and high productivity. The equipment is designed
to give optimal hole quality, reliability, and long service life,
as well as the best blasting results and low total operation cost.
We can design and manufacture the personalized products to meet
your specical apllication, such as changing the tungsten carbide
insert profile (spherical, ballistic, etc.), face profile (flat
face, concave, convex, etc.), and flushing holes.
Applications
• Underground mining
• Down the hole rock drilling
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using
state-of-the-art CNC machinery and heat treatment

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.
