Greenlee 1557SS Hydraulic Punch Sleeve 10 ga SS

Hydraulic punch sleeve for 10 ga mild steel

The Greenlee 1557SS is a stainless-steel sleeve designed to cut clean, accurate holes in material up to 10 gauge mild steel. It measures 1/8" x 2.65" in exterior diameter and is built for use with hydraulic punch drivers. The tool targets electricians, maintenance crews and metal fabricators who need repeatable hole quality in the field or shop.

Compatibility with Greenlee 745 and 7308 units

This sleeve fits Greenlee model 745 punch units and model 7308 punch kit units, so buyers already owning that hardware can add the 1557SS directly. It will not work with punch systems from other brands or with Greenlee units outside the listed models. Users needing a different hole size or a non-hydraulic method should look at other tooling.

Maximum capacity 10 gauge mild steel

The single specification that decides fit is the 10 gauge mild-steel rating; material thicker than that exceeds the sleeve's design limit. If the job requires punching heavier plate, a larger-capacity sleeve or a different punching system is required. No other specification overrides this capacity constraint.
