Description

Multi-Purpose QL60 152mm DTH Hammer Bits

The ROSCHEN QL60 152mm Multi-Purpose DTH Button Bit is engineered for drilling contractors who demand one reliable bit across multiple job site conditions. Whether you are drilling mining blast holes, water wells, geothermal boreholes or construction pile foundations, this versatile bit delivers consistent performance without requiring bit changes.

Cross-Industry Applications

ApplicationTypical DepthPerformance Feature
Mining Blast Holes15-40mHigh penetration rate in hard abrasive rock, minimal hole deviation
Water Well Drilling50-300mEfficient flushing through layered formations, consistent diameter
Geothermal Boreholes100-500mHeat-stable carbide inserts retain hardness at elevated downhole temperatures
Construction Piling10-30mDurable gauge protection through mixed overburden and bedrock

Design Highlights

  • Spherical-Ballistic Hybrid Buttons: Combines spherical gauge buttons for wear resistance with ballistic front buttons for aggressive rock penetration across soft to medium-hard formations
  • Concave Face Profile: All-round application face design optimized for medium to hard rock with excellent hole straightness control
  • Dual Flushing Holes: Two large front flushing passages ensure rapid cuttings evacuation even in wet conditions, preventing bit balling and re-grinding
  • QL60 Spline Design: 12-spline drive with precision-ground shank ensures stable torque transmission and smooth bit rotation under high impact energy
  • YG11 Carbide Grade: Premium tungsten carbide inserts with 11% cobalt binder for optimal balance of hardness and fracture toughness in variable rock conditions

Field Performance

In granite quarry testing, QL60 152mm bits achieved average penetration rates of 0.8-1.2 m/min with bit life exceeding 500 meters in hard rock conditions. In water well applications through alternating sand, clay and limestone layers, consistent 152mm borehole diameter was maintained throughout the full bit service life.
