Knockout Punch 0.492 in 16 Ga

Greenlee 06727 is a hand-held knockout punch designed to cut standard round holes with a nominal size of 0.492 in (123/250 in) in materials up to 16 gauge mild steel. It suits electricians and panel builders who need a single-size tool for conduit entry or component mounting in mild steel, aluminum, fiberglass, or plastic enclosures. The slug falls free and centering marks aid hole alignment.

Suited for single-hole jobs, not for multi-size work

This punch serves technicians who repeatedly need the same 0.492 in hole size and can drive the tool with a manual wrench, hydraulic driver, or battery-operated knockout driver. It is not for buyers who require a kit with interchangeable dies for multiple diameters, nor for those who need to punch material thicker than 16 gauge mild steel.

Nominal hole size 0.492 in (123/250 in)

The decisive specification is the fixed hole diameter of 0.492 in, expressed as 123/250 in, which matches specific conduit or connector standards. If the project calls for a different hole size, this single-die punch cannot be adapted and a different tool or die set must be chosen.

Questions about this item

Does the Greenlee 06727 knockout punch come with a wrench or driver, or must I supply my own?

The punch is designed for use with a manual wrench, hydraulic driver, or battery-operated knockout driver, none of which are included in the box.

The spec lists hole size as 123/250 in and 0.492 in — are these the same punch or different versions?

They are the same punch; 123/250 in is the fractional equivalent of the nominal 0.492 in hole size.

With a 16-gauge mild-steel rating, what thickness of material can this punch actually cut in a workshop?

It is rated to punch through mild steel up to 16 gauge, as well as aluminium, fibreglass and plastic of comparable thickness.
