Durable Flat Shape T38 76mm Button Rock Drill Bit
Threaded drill bits include general,retrac and reaming three series,with stronger button-fixing ability,longer service life,better wear-resistance and impact-resistance performance,widely used in tunneling,underground mining,open pit mining,anchoring and other large-scale construction projects.
Application of the thread rock button bit:
Threaded button drill bits are suitable for powerful percussive drills and top hammers with high speed drifter, the products are widely used in bench and production drilling, extensional drilling,
Advantage of our thread rock button bit:
1. Threaded drill bits are equiped with the hydraulic drilling jumbo and used for crush rock, which are widely used in the tunnel construction, large scale mine (open and underground) and large section tunnel advance in metal mine.
2. Our tools can make all kinds of threaded drill bits, that include R25, R28, R32, R35, R38, T38, T45, T51,ST58, GT60, ST68 and so on, and the head diameter range from 41mm to 127mm.
3. Our R&D team will develop the sharpest industry "teeth", the most suitable bits for different application. The bits with sharp buttons are suit for harrd and mid-hard rock, and have excellent wear resistence and driving speed. The bits with round buttons are extensively used in hard rock with high abrasion and impact resistance.
4. Our button bit is made of top quality steel and tungsten carbide same with well-known brand in the world. For the technic, we take “hot-insertion” processing procedure to insert the buttons into the bit. Optimized designs improve the drilling efficiency. And automatic production line ensure the quality stability of product. Strict requirements of heat-treatment guarantee durability of the bits.
