66-Style Punchdown Blade

This Klein Tools blade terminates 66-style cable connections in cross-connect panels, blocks and keystone jacks. It features a reversible design with one end for termination and cutting and the other for cutting only. Induction-hardened high-carbon steel provides durability and a precision ground edge for clean wire termination. A protective red cap is included.

Suitable for 66-type termination work

Technicians who need to punch down 66-style wiring with a bayonet-style impact tool will find this blade compatible. It fits the Klein Tools VDV427-013 Impact Punchdown Tool and other twist-and-lock socket tools. Installers requiring blades for different connector types or non-bayonet tool systems should look at other options.

Bayonet-style tool compatibility

The blade locks into compatible punchdown tools using a twist-and-lock bayonet socket mechanism. This interface determines whether the blade can be used with a specific hand tool. Verify that the target tool accepts bayonet-style blades before purchase.

Questions about this item

How can I verify the VDV427-016-SEN blade is terminating 66-style connections correctly after fitting it?

Seat the blade in the bayonet socket of your impact punchdown tool, press a wire into a 66 block and confirm the conductor is cleanly cut and seated flush without loose strands.

What comes with the VDV427-016-SEN and what must I supply?

The package includes the reversible 66 punchdown blade and a protective red cap; you need a compatible bayonet-style impact punchdown tool such as the VDV427-013.

Which VDV427-016-SEN version should I choose for my cross-connect panels?

This single model terminates 66-style cables in panels, blocks and keystone jacks with one end for cut-and-terminate and the other for cut-only, so no capacity choice is required.
