New Design DTH Drill Bits For BR Series High Air Pressure DTH
Hammer
Rock drilling tools factory KSQ manufactures DTH Hammer Bits with
BR shank type are available in a various range of sizes and with a
number of custom design features for optimum performance in a rock
formation, designed to match all conceivable applications for water
well industries, stone quarrying, mining and construction.
Shank type: BR2, BR3; and DTH drill bits hole diameter: 3'', 4'',
5'', 6'', 8''(85mm-350mm).
Convex Face
A classic design of rock drill bits 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.
For high penetration rates in soft to medium-hard with low to
medium air pressures. It is the most resistance to steel wash, and
may reduce the load and wear on the gauge buttons, but poor hole
deviation control.
Semi-Ballistic/Parabolic Buttons
Excellent penetration rate, but only suited to medium hard and not
so very abrasive rock formation.
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
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.
Bit Face Shape Selection:
Center Drop Face
For high penetration rates in soft to medium hard and fissured rock
formations. Low to medium air pressure.
Maximum hole deviation control.
Concave Face
The all-around application bit face specifically for medium hard
and homogenerous rock formations.
Good hole deviation control and good flushing capacity.
Convex Face
For high penetration rates in soft to medium-hard with low to
medium air pressure. It is the most resistance to steel wash, any
may reduce the load and wear on gauge buttons, but poor hole
deviation control.
Double Gauge Face
This kind of face shape is suitable for fast penetration rates in
medium to hard rock formations. Designed for high air pressure and
good resistance to steel wash step gauge bit.
Flat Face Bit
This kind of face shape is suitable for hard to very hard and
abrasive rock formation is applications with high air pressure.
Good penetration rates and resistance to steel wash.
