Concrete Bit
how can you get concrete anchors into the ground easy if the concrete is eating up the bit?
Start off with smaller diameter bits and work your way up to the correct size. One problem you’ll have is the rocks in the concrete, too. Use a long, narrow cold steel punch and a hammer to break up rocks you run into as you drill the hole (it helps to hold the body of the punch with a pair of vice grips). Then continue with the drill bit.
An anchor hole is usually 1/2 inch in diameter. Start with a 1/4 inch masonry bit and drill as deep as you need the hole to eventually be. Then, widen it with a 3/8 inch bit. And finally use the 1/2 inch bit. Keep the drill at high speed and vary the amount of pressure you use (push hard, let off, push hard, let off, etc.). If the bit melts or gets eaten up, you’ll just need a new bit. It happens and there’s not much you can do about it.
It takes a while and it’s very tiring. But, that is the best way I have found of accurately drilling anchor holes in concrete.
