The MD6250 drill is built for
efficient drilling of 10m and 12m
benches, including angle drilling
for cast blasting, making it the ideal
drill for mining, quarrying, and
heavy construction applications.
Offering superior performance in
both DTH hard rock and rotary
soft rock applications, the flexible
machine drills holes of 150–250mm
in diameter with bit loads of 22
321kg and 32 655kg, respectively,
for the 11.2m and 13.7m masts.
The MD6250 features angle
drilling from 0 to 30 degrees in
five-degree increments with an
approach angle of 15 degrees for
