Drilling Pipes from Perforator for DTH
TOOL JOINTS
Tundra's tool joints are manufactured from high grade material with special heat treatment on thread connections for extended life time and maximum wear protection. The friction welded or shrink fitted and arc welded connection of the tool joints to the drill pipe body ensures perfect mechanical properties and axial alignment.
DRILL PIPES
  • Blasthole drilling in open pit mining and quarrying
  • For all drill rig types: Atlas Copco / Epiroc ROC, DM, DML, Pit Viper, Sandvik, Driltech, DR, CAT MD, Bucyrus, P&H, Reich and much more
  • Diameter 60.3 - 273 mm (2 3/8” - 10 3/4”)
  • Lengths 0.5 - 13.0 m (1.64’ - 50’)
  • Hardfacing wear protection (option) for extended life and reduced wear
Drilling Tool Joint from Perforator
Hardfacing Wear Protection Option. For high abrasive applications we provide hardfacing, applied either axially or radially on the tool joints. Key benefits are a much better wear protection and longer life of the product.

DRILL PIPE BODY (TUBE)
Tundra's drill pipe bodies are seamless and sourced from premium steel mills. We offer a wide range of grades to optimize your specific application.
SUBS, STABILIZERS & ADAPTERS
For all drill rig types: Atlas Copco / Epiroc ROC, DM, DML, Pit Viper, Sandvik, Driltech, DR, CAT MD, Bucyrus, P&H, Reich and much more.

The high grade material of our subs and stabilizers with special heat treated thread connections results in extended life time of the components together with guarantees an extended lifetime of the components and maximum wear protection.

Our subs are available as top subs, bit subs and crossover subs with optional hardfacing on all sub types.

Tundra's welded blade stabilizers provide smoother holes with higher penetration rates. We offer a wide selection for various drill string sizes in spiral blade or straight blade design with hardfaced blade surface.

SHOCK SUBS
DTH or ROTARY

Shock Sub for slant hole and vertical drilling operations

A floating shock sub utilized in both slant hole and vertical drilling operations where the rig is equipped with a top drive rotary gear box.

Shock Subs for DTH Drilling or Rotary Drilling

A floating shock sub for operations that utilize mid range rotary drills such as the Atlas Copco DML, PV235, Caterpillar MD6240, MD6290, Sandvik D50KS and D55SP where production encounters very difficult drilling conditions. 

Shock Subs for DTH Drilling or Rotary Drilling

The PD6-2 is a floating shock sub utilized on small and mid-range drills for both DTH hammer and rotary drilling applications. In most cases no modifications are required to the drill or drill string.

ROTARY ONLY

Shock Subs for Rotary Drilling Only

Threaded directly into the drive spindle of the rotary gear box, the Cushion Connector will assist in protecting the rotary drive and mast assemblies against both torsional and axial vibrations/shock loading in moderate and extreme drilling conditions. The results will be reduced drill maintenance, increased drill availability and lower production cost.

Smoothdrive Shock Subs for Rotary Drilling Only

A proven product that extends drilling equipment life which equates to lower dollar/foot cost over time. These shock absorbers have demonstrated exceptional isolation in the torsional (X & Y) which means increased protection for the drill machinery.

Utex Rotary Shock Sub King Cobra_edited.

Installation in rotary blasthole drill rigs used in open-pit mining operations. The King Cobra shock absorber is threaded inline between the top motor drive and the drill string below, which continues down to the tricone bit at the surface. Moreover, repairs can be made on the drill machine. Available for Rotary 28" and 22".
