● New upgraded 850W powerful motor drive, drilling operation is more efficient;

● Cylinder made of aviation-grade materials, high compressive strength and good wear resistance; precision gearbox, more durable (aluminum alloy bracket with Makita material, gear double quenching, high-precision rocker bearing);

● With mechanical clutch, it automatically disengages when hitting the steel bar, making the use process safer;

● High precision of drill sleeve, small drill bit shaking, higher operation refinement;

● Equipped with the third-generation stepless speed regulation dustproof switch, effectively resisting harsh dust environment;

● Equipped with EU standard rubber cable (ordinary factories use RVV cable), higher tensile strength and long service life:

● The number of continuous holes punched by a 16mm drill bit is more than 3100, which is more than twice that of ordinary single-item factory products (1200-1500, and then cylinder pulling and tooth punching);

● The whole machine weighs about 3 kg, and the operation comfort is higher than that of a heavy hammer (more than 5 kg);

● With mechanical clutch, it will automatically release when hitting the steel bar, making it safer to use;

● The drill sleeve has high precision, the drill bit shakes less, and the operation is more delicate;

● The round handle and square handle can be equipped with "domestic light hammer classic" imported products of good quality.
