Greenlee K3P-4 4 Conduit Size Standard Round Knockout Punch

Using the Greenlee K3P - 4 is straightforward. First, select the appropriate driver - it can be a Greenlee battery - hydraulic knockout driver, a manual - hydraulic one, or a ratchet wrench. Then, pair it with Greenlee punches and draw studs. When using, make sure the material you're working on, like mild steel, stainless steel, brass, etc., is within the specified thickness limits (10 ga mild steel or 12 ga stainless steel). Since it's optimized for mild steel, when using on stainless steel, expect limited performance. As for maintenance, keep it clean after each use. Wipe off any debris or metal shavings. If you're not using it for a long time, store it in a dry place to prevent rusting. The laser markings on it are there to help you quickly identify parts, so try not to damage them.
