Tapered Rock Drill Bits:It's suitable for H22mm and H25mm taper rock drill rods use. It have three taper degree: 7°, 11°, 12°. It's widely used for hard rock(f=8 18) drilling use. Taper button bits is the best sales product.
With higher drilling efficiency, longer service life, better powder-discharge, better wear-resistance and impact-resistance, easier bit-back performance and other advantages, tapered bits are widely used in metal mine, quarry, tunneling, hydro-electrical engineering and other working conditions.
