Does anybody use 'fostener' drill bits ? I drill @40mm diameter holes through joists, and usually use s.d.s augre bits, {as i find 'flat' bits have limited use}. Has anybody here used these fostener bits ? Thank you.

Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
True Forstner bits are designed to drill flat=-borromed holes, but they have a tendency to wander a wee bit. I think you might find them a bit slow cutting and they are a bit of a pain to sharpen. Do you perhaps mean one of those 3D bits?

I use forstner bits sometimes, to produce large clean holes.
Probably not the best for drilling through a joist though.

Cheers for you views, auger bits it is. { I have now learnt the correct spellings too ! Forstner and auger}.
