The MH505L sinker drill is a time-tested and proven choice. This low-cost pneumatic jackhammer dominates the markets of India and Brazil due to its high return on investment and is designed for drilling through granite, hard-faced rock, quarry drilling, bench drilling, and drilling secondary holes for blasting. It has built-in air flushing which facilitates the removal of drill chipping to reduce the risk of drill jamming (the MH504W is its water flushed counterpart which is used for dust suppression applications). This can drill holes up to depths of 6 meters. This drill also has a robust kick-latch retainer for fast and convenient tool change.
