Picking the wrong drill bit is one of the quickest ways to slow down a project. It wears out fast, drills inefficiently, and puts extra strain on your rig. The right bit, matched to your formation, saves time and money on every meter drilled.
Start With the Formation
Your ground conditions should drive every decision.
- Soft soil and clay: Drag bits and fishtail bits cut efficiently with low wear.
- Medium formations: Tricone roller bits offer a good balance of speed and durability.
- Hard, abrasive rock: Button bits and diamond-impregnated bits are built to handle high compressive strength.
- Core sampling: Diamond core bits deliver clean, accurate samples for geotechnical and mineral exploration.
Match the Bit to Your Drilling Method
The bit must suit your rig and technique. Rotary drilling, down-the-hole (DTH) hammer drilling, and core drilling each need different bit designs. Always confirm that the bit size, thread type, and pressure rating are compatible with your equipment.
Quick Buying Tips
- Know your rock type and hardness before you buy.
- Check compatibility with your rods and rig.
- Compare cost per meter drilled, not just purchase price.
- Inspect bits regularly and replace them before they wear out completely.
