25mm 3-Flute Auger Bit - LT-AUG-25 | Lerin Tools

25mm 3‑Flute Auger Bit – LT-AUG-25 | Lerin Tools

The Lerin Tools 25mm 3‑Flute Auger Bit is designed for fast, clean drilling of medium‑size holes in timber. A self‑feeding tip pulls the bit into the workpiece, while the three‑flute design clears chips quickly to reduce clogging and heat build‑up. This makes it ideal for drilling through beams, joists and studs on framing, decking and fit‑off work.

The precision cutting geometry and outer cutting edges help leave a smooth hole with minimal tear‑out on entry and exit. Made from hardened high‑carbon steel, the bit is built for trade use and performs reliably in both softwood and hardwood when run at the correct drilling speed.

FAQs
What materials can this auger bit drill?
It is suitable for softwood, most hardwoods, LVL, plywood, MDF and chipboard. Very dense hardwoods may require slower speeds and lighter feed pressure.

What type of drill should I use?
Use a power drill or low‑speed rotary hammer (drill‑only mode) with enough torque for a 25mm auger bit. Large auger bits work best at lower RPM to avoid burning the timber.

Is it suitable for deep holes?
Yes, the 3‑flute design improves chip removal. For deeper holes, withdraw the bit periodically to clear chips and prevent binding.

Can I use it in an impact driver?
If the shank is hex and your impact driver is rated for auger use, it may be compatible, but a high‑torque drill usually provides better control for auger bits.
