Halco Rock Tools, UK Manufacturer of DTH Hammers and Bits. Halco pioneered the development and distribution of DTH hammers in the 1950s.
With DTH drilling the power is always on the ‘Business End’ so you will see a faster rate of penetration in medium to hard ground conditions.
 
  
You can expect a longer life from your DTH Drilling equipment because the hammer does all the work less pressure is required from your Rig.
