Hard Rock Drilling Essential : 38mm 5 Ball Tooth Button Bit with Spring Controlled Teeth , 11° Taper Bit
When tackling medium-hard & abrasive rock formations in quarrying, underground mining, tunneling and foundation construction, picking a well-matched button bit directly lifts your drilling productivity and cuts operational costs — a top priority for global construction & mining contractors in 2026.
Today we feature our 38mm 5 Tooth Button Bit With Spring Controlled Ball Teeth, 11° Taper Connection rock drilling bit, a high-demand tapered drill accessory compatible with standard jackleg drills.
✅ Core Design Advantages
Equipped with spring controlled spherical ball teeth, this 38mm button bit delivers stable percussive rock breaking performance. Optimized 5-tooth layout avoids dead zones during drilling, improves hole smoothness and strengthens flushing efficiency to remove rock cuttings rapidly.
The standard 11° taper connection guarantees tight locking with taper drill rods, preventing loosening under continuous impact load; less vibration extends service life of both drill bit and drill shank.
