Features of Hexagonal Drill Extension Rods

• Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;

• 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.

• Cost-effective, good performance with reasonable price.

• Complete types of drill rod for various drilling scenarios.

Applications of Hexagonal Drill Extension Rods

Hexagonal drill extension rods are an essential tool in various industries, especially for applications that require drilling deep or in difficult-to-reach locations. Their hexagonal shape provides a superior grip and torque transmission compared to round rods, preventing slippage and ensuring efficient energy transfer from the drill rig to the bit.

These rods are widely used in conjunction with different types of drill bits, including spade bits, auger bits, and hole saws, to extend their reach. The primary applications include:

• Mining and Quarrying: Used for creating deep holes for blasting, rock reinforcement, and production drilling in both open-pit and underground operations.
• Construction: Essential for foundation work, micro-piling, and drilling holes for anchors and bolts in various civil engineering projects, such as bridges and high-rise buildings.
• Tunneling: Utilized for drilling blast holes to excavate tunnels and for installing rock bolts to stabilize the tunnel’s structure.
• Geotechnical and Exploration Drilling: Employed to obtain deep core samples for geological analysis and to assess ground conditions for construction projects.
• Electrical and Plumbing: Used by electricians and plumbers to drill through walls, floors, and other structures to run wires and pipes in confined or hard-to-reach areas.
• General Purpose: Ideal for any project where a standard drill bit is not long enough, such as drilling through thick timbers or multiple studs.
