Mining Tools 89mm T38 Rock Carbide Drill Bits With Drop Center
Rock Carbide Drill bit
Rock Carbide drill bits are made by high quality alloy steel bar and tungsten
carbides. Through heat treatment, our drilling tools are tough
enough to meet rock drilling demands and have the least loss of
energy while drilling the rocks. Besides, we can design customized
thread button drill bits according to different drilling
application, and custom drill bits are applicable to drill soft
rock, loose-medium rock and hard rock.

Button carbide shape
| Button shape | Application |
 | Hemispherical Buttons Universal button for all rock formations,best suited to hardest and
very abrasive rock formations |
 | Parabolic button Excellent penetration rate,but only suited to medium hard and not
so very abrasive rock formations |
 |
Conical button
For soft to medium rock hardness,more aggressive with faster
penetration rates.

 |
Ballistic button
Similar to Parabolic buttons,used for soft to medium hard and not
so abrasive rock formations,excellent in penetration rate |
