Description
High grade tungsten carbide inserts
Bit bodies manufactured from high grade steel and processed using
state-of-the-art CNC
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.
• Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
