Top Hammer Drilling Tools R32 51mm Retrac Body Flat Face Spherical
Button Drill Bit
Button drill bit Made with high quality of best quality alloy steel
bar and tungsten carbide, through heat treatment like
Atlas.Suitable for powerful percussive drills and top hammers with
high speed drifter, , such as Atlas Copco 282 rocket boomer, Atlas
Copco 352 rocket boomer jumbo, AtlasCopcoD7roc, FurukawaHCR 1200,
Tamrock, and Ingesoll Rand ECM660, the products are widely used in
bench and production drilling, extensional drilling, our products
with comparative advantages of the more prominent cost-effective ,
our products have been recognized as high-quality brand of
rock-drilling tools made in China.
The Retrac Bits are widely applicable to mining industry, tunneling
and underground engineering, open pit, construction drill, blast
industry, civil engineering operations, road, gas line, pipe and
trench projects, quarry work, rock anchoring and ground
stabilization projects, water well industry, etc. This type design
can get better hole deviation control while drilling, it can get
bit back easily while the bit is jammed during drilling.
