The Mincon MQ range of DTH hammers is designed around proven technology to perform at the top end of the performance scale compared to other tools on the market. These tools are excellent for all types of drilling applications including residential geothermal, production quarry drilling, seismic drilling and construction drilling.
The MC Range drill bit is significantly shorter than conventional DTH bits and does not use a foot valve. The MC Range drill bit is also fully contained within the hammers chuck. This patented feature dramatically reduces the incidence shanking and spline wear even when drilling in broken or softer ground. This greatly reduces bottom end damage to the DTH hammer and bit and reduces the potential of down time due to tool failure.
