Drill Strings for Top Hammer Drilling

TechCom supplies drill strings, drilling components and Epiroc spare parts for mining, quarrying, tunneling and construction applications. Our range includes solutions for current Epiroc drilling equipment as well as components for earlier Atlas Copco Secoroc systems.

Epiroc and Atlas Copco Secoroc Drill Strings

A top hammer drill string connects the rock drill to the drill bit and consists of components designed to work together as a complete drilling system. Typical components include shank adapters, drill rods, couplings and drill bits.

Our range includes drill string components for Epiroc and Atlas Copco Secoroc equipment used in surface and underground drilling. Along with drilling tools, TechCom supplies Epiroc spare parts and components for the maintenance and operation of mining and drilling equipment.

Drill String Components

• Shank adapters – provide the connection between the rock drill and the drill string.
• Drill rods – form the main section of the drill string and transmit drilling forces toward the bit.
• Couplings – connect threaded drill rods and other drill string components.
• Drill bits – perform the rock-breaking operation at the end of the drill string.

Drill String Systems and Applications

Epiroc offers several drill string systems for different drilling applications, including T, R, SR, TC, ET, COPROD and tapered drill strings. Available thread systems and dimensions depend on the rock drill, drilling method, hole diameter and operating conditions.

Drill strings are used in applications such as bench drilling, production drilling, underground face drilling, tunneling, rock bolting and construction.
