Audited Supplier We choose to use superior steel suitable for hot insertion technology, by which the drilling bits body will hold the carbide buttons so tightly that reduce the risk of buttons' dropping out of the holes.
In order to better resist the abrasiveness of rock, spherical shape will be a good option for the carbide if high speed is not a necessity.
Thread: R32
Diameter: 45mm
Gauge Buttons: 6*9mm
Front Buttons: 3*8mm
Skirt Design: Standard
Weight: 0.8KG
Carbide Design: Ballistic/Domed
R32 Threaded Button Bits is the most important size for drifting and tunneling drilling job.
Customization is welcome ,we are always be here for your solutions,when you need in.
Bit button selection
round button /Domed (Usually for very hard rocks)
Ballistic button or Double gauge button (Ususally for medium hard rocks)
Sharp button or (Usually for soft rocks)
Drill bits face shape selection
| Bit Face Shape Selection | Brief introduction |
| Drop Center Bit | 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. |
