GS658L– Sinker Drill


The GS658L Sinker Drill is a low-cost pneumatic jackhammer and is well known for its high return on investment and is tailor-made to drill through hard faced rock, granite, bench drilling, quarry drilling and secondary holes for blasting. The risk of drill jamming is reduced by the means of built-in air flushing which removes drill chippings.  The drill enables a fast and convenient tool to change with the help of a robust kick-latch retainer.
