Hi all,
I spent last weekend attempting to screw and glue 9mm ply to a concrete floor using concrete screws (tapcons). I used the concrete drill bit supplied with the box of 100 tapcons I bought for the job (5/32 bit), then when it was knackered a 4mm bit. for some reason the holes were clearly not big enough - I broke a few phillips drive bits, and only about one scew in ten would go in without snapping off - a very frustrating experience . .
I wondered if anyone had any experience of using tapcons and could suggest what I might be doing wrong . . .
thanks!
