Tungsten Carbide Drill Bits T38 115mm Retractable Drill Bit Top
Hammer Drilling Tools for Hard Rock
Product Description:
The Retrac Bits are widely applicable to mining industry, tunneling
and underground engineering, open pit, construction drill, blast
industry, civil engineering operations,
road, gas line, pipe and trench projects, quarry work, rock
anchoring and ground stabilization projects, water well industry,
etc,.
This type design can get better hole deviation control while
drilling, it can get bit back easily while the bit is jammed during
drilling.

| Bit Face Shape | Introduction |
| Drop Center Face | For high penetration rates in soft to medium hard and fissured rock
formations,
Low to medium air pressures. Maximum hole deviation control. |
| Concave Face | The all-round application bit face specifically for medium hard and
homogeneous rock formations.
Good hole deviation control and good fishing capacity. |
| Convex Face | For high penetration rates m soft to medium-hard with low to medium
air pressures.
It is the most resistance to steel wash. And many reduce the load
and wear on the gauge buttons.
But poor hole deviation control. |
| Double Gauge Face | This kind face shape is suitable for fast penetration rates in
medium to hard rock formations.
Designed for high air pressures 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 formations in applications with high air pressure.
Good penetration rates are resistance to steel wash. |
