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).
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.
Excellent penetration rate, but only suited to medium hard and not so very abrasive rock formation.
• 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.
The all-around application bit face specifically for medium hard and homogenerous rock formations.
Good hole deviation control and good flushing capacity.
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.
