MH505HB – Pneumatic Hand Held Rock Drill
The MH505HB Sinker Drill is a footrest equipped version of the MH505L which is a time-tested and proven choice. This low-cost drill dominates many markets due to its high return on investment and it is designed for drilling through granite, hard-faced rock, quarry drilling, bench drilling, construction drilling, and drilling secondary boreholes for blasting.
The MH505HB has built-in air flushing which facilitates the removal of drill cuttings to reduce the risk of "bogging" the drill. It also comes with a water flushing option for dust suppression if required. The footrest increases operator comfort and enables faster drilling. The MH505HB can drill holes up to depths 6 meters deep. The MH505HB drill also has a robust kick-latch retainer for fast and convenient tool changing.
