Product Details
12 Degrees 41mm Long Skirt Rock Drill Tapper Button Bits
Tapered equipment affords drillers the ability to change drilling
bits whilst still using the same drilling rod. Drillers choose
tapered button bits for faster drilling penetration rate. Different
taper sizes have different characteristics when it comes to the
“knock-off” index – the smaller angle will prevent the bit from
spinning.
Application
• Dimensional Stone Industry
• Underground Mining
• Tunneling
