Mining bit DTH COP66 165mm button bits for rock drilling
| Different name： | Pneumatic DTH bits/ air bits |
| Main application： | for mining/well drilling/quarry/rock drilling/ blast hole drilling |
| Core specification parameters： | COP66 high air pressure DTH bits |
| Applications: | Widely used in mining, quarrying, exploration, water-well, geothermal, solar and construction/geotechnical drilling projects |
Description
Cop 66 is designed for Atlas Copco SmartROC D65 drill rig. Comparing to the COP 64 Gold, penetration of COP 66 is 15% faster and is more easily adjustable for feed force and rotation, making life easier for its operator and business more productive.
Specification:
Code: COP66
Material: 25SiMnCrNi2MoVA
Tungsten carbide: YK05
Processing: Forging
Application: Mining, Blasting, Quarry, Water Well drilling
Bit Shank: COP66
Bit Diameter: 152-203mm
According the different shape of head, the DTH bits can be classified into flat face、convex face、drop center、Concave face bits.
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 an resistance to steel wash.
Convex Face Bit
For high penetration rates in soft to medium-hard with low to medium air pressure. It is the most resistance to steel wash, and may reduce the load and wear on gauge buttons, but poor hole deviation control.
Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressure. Maximum hole deviation control.
Concave Bit
The all-around application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good flushing capacity.
