Spherical And Ballistic Button Bits With Drop - Center And Flat Face Shape

Specifications

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
