Buying Guide

Match punch size to your conduit needs

Choose a die diameter and thread standard that fits the conduit or knockout pattern you commonly work with, such as 3-1/2" or 4" dies and 3/4-16 UN threads

Pick manual vs. hydraulic based on workload

Hydraulic kits (10‑ton or similar) reduce effort for frequent or thicker metal work, while manual punches can be adequate for occasional holes and lighter gauges

Check included size range in kits

Kits that list a range like 1/2"–2" provide more versatility across common conduit and knockout sizes without buying separate dies

Consider build quality and rated tonnage

Look for robust die materials and a rated tonnage (e.g., 10 ton) to ensure consistent, square cuts through steel or conduit bodies

Mind compatibility with existing tooling

Confirm thread types and hydraulic coupling standards match your current punch driver or hydraulic ram to avoid mismatched components
