1/4'' Bit Adaptor to 1/2-20 UNF thread
1/4'' Bit Adaptor to 1/2-20 UNF thread
With the 1/4'' bit adapter (6.3 mm), you can also use drill chucks with your cordless bit screwdriver, so that you can also use it with twist drill bit with a cylindrical shank.
The adapter is compatible with drill chucks with a 1/2"-20 UNF threaded mount.
Inserting the adapters creates a plug-in connection, which also reduces a runout accuracy of a drill chuck. It is therefore mainly suitable for normal drilling work. For precision work, we recommend not using threaded or plug-in connections. Here, we recommend a drill chuck with a taper mount and a machine with a Morse taper mount.
