The MH505L Sinker Drill is a time-tested and proven choice by many users.

This low-cost pneumatic unit 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, construction drilling and drilling secondary boreholes for blasting. The MH505L has built-in air flushing which facilitates the removal of drill cuttings to reduce the risk of "bogging" the drill.
