Anybody using these at the moment?

Any body here been using these? I normally use auger bits or speedbits for joist drilling. Do these work well and do they have a decent working life?

There was a thread about these a while ago, upshot is they work very well.

Yes I use them, just used them again this morning. I use the smaller one the most and although its still very sharp, its just lost its edge a bit, I gone through in excess of 100 joists with it probably though and given it a bit of abuse. But... its still going strong and works well.

They work great in an impact driver!
