3 threading adapters in the overview

3 thread adapters with which you can cut threads with the cordless drill

In the past it was more difficult to cut threads with a cordless screwdriver, because the torque of the cordless drills was not strong enough. And on the other hand the taps with square shank did not fit into the drill chuck with hexagonal shank.

But a lot has happened in the last few years. The cordless screwdrivers have much more power to realize higher torques. Read here, which possibilities there are to cut a thread with the cordless screwdriver.

Danger information for thread cutting with cordless screwdrivers

When threading with the cordless screwdriver, please make sure to adjust the torque to prevent overtightening and injury. Please use a cordless screwdriver with slip clutch or torque regulator or torque limiter!

How to tap a thread with a cordless drill

We present 3 thread adapters with which you can reliably perform thread cutting. Without risk of injury but in DIN-standard quality.

1. tapping adapter | The tool holder with hexagonal shank

The tapping adapter or tool holder with hexagonal shaft can be clamped into the drill chuck of the cordless screwdriver. You can clamp cutting taps and hand taps in the tapping adapter itself.

3. combination tap bits

The combination tap bits are not tapping adapters, but for the sake of completeness they should be listed here. With the combination tap bits with hexagonal shank you can carry out three operations in one. Core hole drilling, tapping and deburring. The bits have a “¼” hexagonal shaft and can therefore be clamped in all cordless screwdrivers. They are suitable for steels, metals and plastics. Due to the system they are only suitable for short through holes. The bits are manufactured according to factory standards.
