Technical Information
Top Hammer vs DTH Drilling

Taper button bits are designed for air leg or hand-held jack hammer drillers in quarrying and mining applications. Unlike thread button bits used for long hole drilling, these tapered bits connect via taper rods for enhanced stability and performance.

Button Bit Selection Guide

Concave Face: Ideal for all formations, especially deep well drilling with excellent hole perpendicularity.

Convex Face: Suitable for moderate hardness strata with good drilling efficiency and moderate borehole perpendicularity.

Flat Face: Recommended for extremely hard formations, fractured rock, and complex geological conditions with superior borehole perpendicularity.
