T45 89mm ,T51 89mm Retrac button Rock Drilling Bits for mining and quarry
Using high-quality alloy steel imported from the United States and the best cemented carbide made in China , we produce all threaded button bits through hot pressing technology .
2.Materials and produce process details of Rock Drilling Bits
Material - we use 45CrNiMoVA production of tungsten carbide and YK05 our cone drill bit , both of which are world famous drill production materials . Advanced technology --- we produce round cone drill bit using the best technology hot - button-cone drill bit production advanced technology .
When the permeability decreased or carbide signs of damage , should be re-grinding button drill
Fixed grinding program will usually bring good working practices .
For example , check bits , and then again at the shift end milling or after a certain number of holes . Premature grinding is not necessarily uneconomic , because less needs worn carbide . It is better to re-grind rather than reduce productivity due to damage .
Correct grinding greatly increases the service life of the drill bit . But equally important , it also improves the performance of the entire drilling operation , especially straightness of the hole .
3.A comprehensive range of various button bits shown as below :
| Thread sizes | R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, T45, T51...... |
| Head diameters | 33mm ~ 152mm |
| Face designs | flat face, drop center, uni-face |
