Outstanding advantage:
√ Italian Cieffe atmosphere-controllable sealed quench furnace for heat-treatment
√ Modern CNC machines for accurate finishing's which contribute to the excellent performance of all our drilling tools
Package:
Single carton with foam/bubble bag inside and wooden case outside.
Structure Feature:
1. Standard API Thread
2. Top sup with cement carbide button (Alternative)
3. Internal parts are highly assembled to avoid interactive wear and hammer's reliability is increased.
4. Piston case: Using superior alloy steel, even better reliability and longer life after heat treatment.
5. Hammer front structure design: when pulling out the hammer, the last impact of the piston would fall on the step of piston case, ensuring the safety of the driver sub splines and the retainer ring.
