Drilling Tools

Reamers / Cutters	Flushing heads	Drill rods (vertical)	Connectors / couplings	HDD drill rods

A drilling rig must be equipped with the proper tooling: reamers, drill rods and a flushing head. Drill rods come in various lengths and differ by connector type — trapezoidal or tapered. Reamers are of two main types: wing augers and PIKO bits.

Flushing pipes

For deep-well drilling, you need a certain number of drill rods depending on their size and the maximum depth of a hydraulic drilling rig. Drill rods are hollow; on each side a connector with trapezoidal or tapered thread is welded.

Wing auger

The most optimal tool for a manual rig is a wing auger with three blades, each having a cutting edge. The edges wear faster, so VK8 hardmetal plates are welded on to extend service life.

PIKO reamer

To speed up drilling in hard rock with a manual rig, PIKO reamers are used instead of wing augers on difficult jobs.

Flushing heads

A flushing head delivers drilling fluid through the drill string to the cutting tool.

HDD drill rods

Drill rods for horizontal directional drilling (HDD) are a core component of the steerable boring system.

They are used to:

• Transfer torque and thrust from the rig to the drilling tool,
• Deliver drilling fluid through the internal conduit to the drill head for cooling, lubrication and cuttings removal,
• Connect successive sections during reaming and pipeline pullback,
• Provide stability and directional control thanks to high strength and stiffness.

With the right diameter, wall thickness and length, the rods enable safe and efficient HDD in various ground conditions — from soft soils to harder formations.
