The Irwin 8 x 380/300mm auger bit is the extended-length option for drilling deep, clean holes in timber and nail-embedded wood. Its self-pulling thread feeds the bit into the material while the spiral 'LEWIS' groove clears chips for fast, accurate drilling at depth.
The peripheral cutting edge keeps holes clean with minimal spalling, while the extra length suits drilling through thick beams, posts and stacked timbers. Add other diameters to make up an Irwin auger drill bit set for cabling and plumbing runs.

Really pleased with this
Honestly one of the easiest online purchases I have made. Ordered in the evening and had a tracking number by morning. Delivered to Canberra in 3 business days. Product is well made and does exactly what we needed. My partner is happy with it too. Highly recommend.

Great quality
Good quality and arrived ahead of schedule. Very happy.
Brilliant Aussie deal
Been buying Irwin gear for years and this is one of their better ones. The Irwin 8 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
No complaints at all
Exactly as described. Quick shipping. Would buy again.
Works perfectly out of the box
Was exactly what I needed for the price I paid. Arrived well packaged and was easy to set up straight away. Already recommended it to a friend who is also thinking of getting one.
