end, they are connected with drill bits via thread also. Threaded
rod could be connected with other drill rods to constitute a
complete set of threaded connection whole drilling tools for
drilling. Threaded drill rods could be connected with one piece of
shank adapters and drill bits, or connected with lots of adaptors
and bits. And ther can also be used in shallow holes and small
diameter rock hole drilling, the applicable scope is wide, drilling
speed, impact energy transmission loss is small, high drilling
efficiency, easily to realize the drilling mechanization and
improve the superiority of drilling conditions. Therefore, thread
extension drill rods share a very very big proportion in the whole
drilling fields.
Thread extension steel bars for rock drilling must own high fatigue
strength, elasticity, rigidity and toughness, but strength and
toughness is contradictory. The thread at both ends of the thread
rods is a whole set of drilling tools, it's the key part of rod. It
is well known that the performance of the material could be played
well only after going through heat treatment to release its maximum
potential, therefore, the choice of material and heat treatment
process are important on an equal basis.
Our main top hammer rock tools include shank end rod, tapered drill
rod, tapered button bits, extension rod, M/F rod, drifter rod,
