AMZCNC Hydraulic Knockout Punch Kit 1/2-2 in | 8 Ton Conduit Hole Cutter Set

Efficient, durable knockout punching for electrical and metalwork projects

The AMZCNC Hydraulic Knockout Punch Kit is designed to help you create clean, precise conduit holes with steady, controlled effort. Built for durability and long-term use, this kit brings a reliable hydraulic punch to your toolbox, enabling smooth operation and steady leverage during demanding tasks. The kit’s robust construction and thoughtful ergonomics can translate to faster workflow and less hand fatigue over time.

Power, versatility and precision

• Powerful 8 US ton punching capacity delivers decisive performance when cutting through metal and material combinations typical in electrical installations.
• Six die sets sized for conduit fittings from ½ inch to 2 inches, covering common conduit requirements in one kit.
• Punching thickness capacity supports up to 1/8 inch (10 ga) steel and up to 1/16 inch stainless steel, enabling a range of project needs.
• Versatile punch options include steel, stainless steel, brass, copper, aluminum (soft alloys only), fiberglass, and plastic, expanding your material compatibility.
• Convenient operation pairs a drill bit and driving bolt with the knockout set for clean, uniform holes, while a long plastic handle minimizes slipping and enhances force transfer.
• Compatibility designed to work with GREENLEE and other domestic punch tooling via 3/4-16 threads, offering upgrade flexibility for existing setups.

Real-world use and benefits

• Ideal for electrical installations, service panels, and conduit runs where dependable, repeatable holes are needed.
• Great for workshop fabrication and renovation projects where access is limited and precision matters.
• Users can experience smoother operation with reduced effort due to the lever-action design and ergonomic handle.

What to expect in practice

In typical use, the kit enables you to punch clean, round holes with minimal burrs, helping maintain alignment and reducing rework. While outcomes depend on material and setup, the combination of die sizes and the 8 ton capacity is intended to provide consistent results across many common conduit applications. Always follow safety guidelines and inspect tooling before use to maintain performance over time.
