T45 button bits are high-performance top hammer tools designed for bench drilling, underground long-hole drilling, and tunneling applications. Available in diameters from 76mm to 127mm, these bits feature hardened tungsten carbide buttons mounted on high-quality alloy steel bodies, delivering optimized penetration rates in hard and abrasive rock formations.
Key Features and Specifications
Diameter Range: Common sizes include 76mm, 89mm, and 102mm
Button Types: Spherical/Dome buttons for hard, non-abrasive rock or Ballistic buttons for softer, abrasive rock
Face Designs: Standard, drop-center, and retrac configurations for various drilling conditions
Face Design Options
Flat Face: Optimal for hard rock formations, providing stability and high penetration rates
Drop Center: Ideal for straight hole drilling applications
Retrac: Facilitates easier extraction of drill strings in broken or fractured ground conditions
Applications
Ideal for construction projects, quarry operations, and mining applications including bench drilling and long-hole drilling in various geological conditions.
Performance Advantages
Increased Productivity: Engineered for faster penetration rates and improved drilling efficiency
Extended Service Life: High-quality carbide construction ensures minimal energy loss and wear resistance up to 5-6 times better than conventional tools
Optimal Energy Transfer: Specialized button designs ensure maximum impact energy transfer to the rock surface
