No. 215-4 1/2" (#4) Stainless Steel Plain Rim Grommet Die Set

The No. 215-4 1/2" (#4) Stainless Steel Plain Rim Grommet Die Set, made by C.S. Osborne & Co., is a professional-grade die set designed for precision setting of 1/2" (#4) stainless steel plain rim grommets. CNC-machined from drop-forged, polished, high-grade tool steel, the dies are engineered for precision, durability, and long-term performance. Perfect for high-volume canvas, marine, and upholstery workshops, this die set delivers consistent, professional results in the most demanding environments.

We recommend using a soft-face mallet—such as the No. 395-3U Urethane Split Head Hammer—with this grommet setting die to prevent "mushrooming" of the punch and ensure clean, precise grommet installation.
