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.
