The No. 500-4 1/2″ (#4) Grommet Hole Punch, made by C.S. Osborne & Co., is a durable, mallet-driven hole punching tool used to cut perfect sized holes for 1/2″ (#4) grommets. Made from hardened drop-forged steel, it features a tapered inside for easy clearance of fabric cuttings.

We recommend using the tool with a soft surfacesuch as a cutting padunderneath the fabric to prevent “mushrooming” the cutting components.

Sold each.
