Blue Diamond Auger Bits - Rock Bit - 105305

Introducing our Auger Rock Bits, designed for solid rock and concrete drilling. Featuring cast tooth pockets and drive-in carbide bullet teeth, with a sturdy ¾” thick boring head and standard 4’ length, they excel in tough drilling tasks. Please note: These bits are not suitable for use in dirt. They require a minimum down pressure of 3000 lbs for optimal performance.

What Our Experts Think
  • Rock-Penetrating Design: Built to drill through hard, rocky soils and compact ground with high torque.

  • Heavy-Duty Construction: Reinforced steel and heat-treated cutting edges resist wear and impact.

  • Aggressive Flute Geometry: Deep, wide flutes help eject drill cuttings and prevent clogging.

  • Tough Tip Design: Hardened carbide or alloy tips to handle abrasive and stony conditions.

  • Specialized Use: Best for drilling in rocky terrain, hardpan, or soils with embedded stones.

Q&A

Q: What is the Blue Diamond Auger Bit — Rock Bit (model 105305)?
A: A premium auger bit designed specifically for drilling through rock, shale, and extremely hard soil conditions.

Q: How does it operate?
A: It mounts onto an auger drive and spins under hydraulic power; the hardened tip breaks rock while the flute removes the debris.

Q: Is it durable?
A: Yes — constructed with reinforced materials, hardened tips, and heavy steel bodies to withstand abrasion and shock.

Q: What diameters or depths can it handle?
A: Dependent on your auger drive’s torque and the bit’s size — suitable for medium to larger diameter holes even in very tough ground.

Q: What equipment is it compatible with?
A: Designed to attach to standard auger drives that mount to skid steers or compatible drilling machines.

Maintenance Tips
  • Inspect Cutting Tip & Flutes: Check for chips, cracks, or wear before use.

  • Sharpen or Replace Tips: Maintain sharpness to improve drilling efficiency.

  • Clean After Use: Clear all debris and rock fragments from flutes to avoid clogging.

  • Check Mounting Connection: Ensure secure fit to the drive shaft; avoid wobble or misalignment.

  • Store Carefully: Keep in a dry, secure place to protect the tip and prevent rust.
