I brought some of those blue Irwin bits about 2 years ago, the first hole I drilled with the 32mm bit going up through flooring into stud wall (which was already tacked at the bottom, so couldn't do it from above) straight into a nail! So moved to the left 30mm and tried again, straight into another nail! So drilled in between the two previous atempts and luckily got throught that time. Wasn't too impressed with myself that night!

Those bits are great when new (or not mangled by nails) for going through joists, very quick, much quicker than flat wood bits or other auger bits. Especially when used with angle drills with a lot of torque. I have used them in a impact driver when without power, but never the bigger sizes 20mm max

I use the smaller makita angle drill with various wood bits/augers......I got sick of my battery version, crap go for mains

I've got one of them smaller ones but theres not enough torque to use my fav irwin bits though. Anyone want it lol

Use my Bosch combi, nice and short and fits between any joists with an irwin blue groove attached.

I use a 230 dewalt if there is alot to do and long auger bits need to invest in an angle drill far easier ,worst bit is if it grips and it can be broken wrist time most of the time i use an 18 volt dewalt brill

Hi guys
Needed to drill 32mm holes to pull pipes through. Hired Makita angle drill & bought new flat bits. Drilled holes easy so will be looking to buy one for next job

Not sure if you mean these ones, they are the Blue Groove on steroids....

Irwin Blue Groove Power Bit Set (20, 22, 25mm)

And at that price a real bargain too, as the list price for the 25mm is £10 on its own.

These are the ones that I think IRB is referring to, and again cheap as chips...
