Screw thread is too quick for cutting ability of blades causing them to jam. Flat bit style prong is required.

Good design for the cutter but it needs to cut into the wood faster; good connection and reasonably priced in at case

Good quality worm drive auguer bit. Purchased to pre drill timber prior to using a 14mm SDS drill bit to avoid blowing out the rear of the timber. The drill bit cuts smooth and quickly and is good enough quality for site use suitable for use in an impact or drill

Good sharp tool

Elementary Dear Watson Verified Purchase

I had a number of holes to drill in some joists and this bit just sailed through them, ideal for this sort of job.

OK but agressive.

Why five stars, because it did a good job and I'm happy with it.

The only caveat is be sure you've something with enough torque to drive it. I find with augers( I've a 40mm one) that sometimes the screw lead clogs and doesnt pull it in.
In the bigger sizes, I drill a fine pilot hole say 4mm ? Smaller than the lead screw diameter and it seems to fire right on in.
The other thing is, it hit brick before it cleared the hole.
I drilled a masonry bit relief hole for the lead screw to enter..perfect.

FAST

Dymo Verified Purchase

I don't think it is 5 times faster than flat drill , but it was definitely faster and easier and smoother , but still i had to give it little push , drill drives itself for first few mill but then you need to give a little push.

Well made. Handled over 100 cuts with ease

Well made, doesnt blunt easily but only use it for wood. We used this to run cables through the joists safely.

Mostly OK

It's so keen it tends to get stuck in solid oak and then you have a problem. Does the job on softer woods.

Does what it says and more👍

Although i didnt use this conventially it performed as i wanted it to.
I ground the lead spur off and used it as a reamer in an oak balustrade to make predrilled holes that were off..plumb.
Based on that experience im more than happy with my purchase.
