Problem: The recommended Tapcon bits are too short. The screws bottom-out and spall the concrete.
Sometimes I can buy a longer bit. Sometimes I can't.
My workaround is to drop a 3/4" screw down the chuck before I insert the bit into my hammerdrill. Sometimes the chuck jams. Sometimes I lose the screw. Always it is extra steps and frustrating. Inconvenient.
I notice that the Tapcon bits have a flat. I assume the flat is to keep the bit from slipping in the chuck. My hammerdrill doesn't have a flat inside the chuck. My pro told me all hammerdrills have a flat inside the chuck. I looked at the drill motors on his shelves, but near as I can tell, none of them have flats.
When Tapcon recommends a particular bit for a particular anchor screw, they MUST be thinking of some kind of chuck that I've never seen - something that leaves half-inch more bit protruding.
Tapcon was unresponsive to questions.
I have a lot of 5/32" holes to drill. I want a drill motor with that chuck. Who makes it and where do I get it?
Thank you. Thank you. Thank you.
