MH505L – Pneumatic Jack Hammer
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.
The MH504W is its water flushing counterpart which is used for dust suppression applications. The MH505L can drill holes up to six meters deep. The MH505L hand Drill also has a robust "kick-latch" retainer for fast and convenient tool changing.
