Mining Drill Rod T45 Extension Drill Rods Rock Drilling Rig Machine Tools

Description:

Our drifting and extension drill rods are for in drifting, tunneling, long-hole drilling, bench and production drilling industries. These rods are produced with round or hexagonal sections in all common thread designs, and in Male/Male (M/M) or Male/Female (M/F) connections. All our drifting and extension drill rods are heat-treated with carburization or high frequency, combinated with phosphorization.

The round cross sections are more prevalent for extension drilling applications. A round rod has less material and thus is lighter to handle and less expensive than an equivalent size hexagonal rod. While hexagonal rodis particularly advantageous for drifting and tunneling drilling. The increased rigidity of hexagonal drill rods enablesthem to abating hole-deviation and enhances flushing for cleaning holes. Even with the larger cross section, hexagonal steel can still accommodate the same diameter bit as that of an equivalent round steel.
