What to Compare Before Buying
- Tool connection: Check that your impact tool has a 1/2"-20 UNF female thread.
- Tool type: This is for impact drivers, impact wrenches and SDS rotary hammers in rotation mode only, not standard drills with a fixed chuck.
- Bit size: The chuck is stated to grip bits from 1.5 mm to 13 mm, so compare that range with the bits you plan to use.
- Adapter format: Confirm whether you need the 1/4" Hex, 1/2" Square or 3/8" SDS-Plus connection.
Compatibility, Size and Fit
The key compatibility point is the 1/2"-20 UNF female thread on the tool. The adapter is not suitable for standard drills or any tool with a built-in, non-removable chuck. For SDS-Plus use, it is stated to work with an adapter and only in rotation mode.
