Tapping threads straight

[Atlas Knife Company]

I've also tapped thousands of holes with a spiral tap in a cordless drill. On a bosch 12v I set the torque to 12, on a Ryobi 18v I set the torque to 8. The only reason it would tap crooked is if the drill wasn't held straight.

I have one of these now, and I love it. I've tapped 1/2"-13 threads in seconds with one. Give me a cordless drill like it with separate forward and reverse triggers and I'd die happy.

From what I have read about tapping titanium, that IS actually how you should do it. Although a drill press/mill would be a safer bet so there is much less lateral stress on it.

Safer, maybe? But oh so slow. I don't brake taps in the cordless drill & 0-80, 1-72 taps are so very easy to brake.

Metabo has just that. But without two triggers. It uses push-pull reversing control just like many other tapguns. The tool also can be used like any other cordless drill.
