T45 Retractable Drill Bit with Spherical Buttons Suitable for Abrasive and Hard Formations
Retractable rock drill button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength).Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.
Suitable for powerful percussive drills and top hammers with high speed drifter, such as Atlas Copco 282 rocket boomer, Atlas Copco 352 rocket boomer jumbo,AtlasCopcoD7roc, Furukawa HCR 1200, Tamrock and Ingersoll Rand ECM660,the products are widely used in bench and production drilling, extensional drilling, our products with comparative advantages of the more prominent cost-effective as the famous brand in the world, our products have been recognized as high-quality brand of rock-drilling tools made in China.
How to choose the bit tooth type:
Spherical buttons: The height of exposed teeth is low, mainly used in the very hard rock formation above F14, to improve wear resistance, to prevent the situation of debris, it should take lower drilling speed.
Ballistic buttons: It can expose more height of buttons, mainly used in soft rock and ordinary rock below F12, with quicker drilling speed, but encountered hard rock, very easily to happen buttons debris phenomenon.
Product Advantage:
• Recommended for eliminating hole deviation
• Widely used drifting and tunneling
• Bit face design is ideal for medium-hard to hard abrasive rock
