AMZCNC 2-1/2 Inch Conduit Punch and Die for Hydraulic Knockout Driver – 3/4-16UN Thread, Hardened Tool Steel

The AMZCNC 2-1/2 inch conduit punch and die is built to handle knockout needs with reliability. Crafted from hardened tool steel and finished in a durable black oxide, this tool balances strength and precision for repeated use in demanding electrical and metalworking environments. It is designed to work with a hydraulic knockout driver, delivering steady performance across compatible materials and job sites.

Key specifications help you plan projects with confidence. The conduit fitting size is 2-1/2 inch, and the actual hole size is 2.91 inch, giving you a clear target for accurate installations. A punching force of 10 tons provides the necessary leverage for clean metal removal without excessive effort. It uses a standard 3/4-16UN draw stud, ensuring compatibility with common hydraulic systems. The punching thickness capacity supports 1/8 inch (11 ga) steel and 1/16 inch stainless steel, enabling efficient work on thin gauge materials.

Materials you can punch are listed to guide material selection. This die handles steel, stainless steel, brass, copper, and aluminum (soft alloys only). It can also process fiberglass, plastic, and other similar substrates. When approaching projects, keep in mind that hard alloys such as 6061 or 7075 may not be suitable for this tool, so plan material choices accordingly for best results.

What you can expect in real use

In practical terms, the AMZCNC punch and die is designed to deliver steady, controlled metal removal with minimal effort when paired with compatible equipment. The hardened tool steel construction contributes to a long service life, while the black oxide finish helps resist character marks and corrosion in typical shop environments. Expect clean holes, predictable performance, and a reliable partner for conduit installation tasks that require precision and repeatability.

Tips for best results

• Verify the conduit size and draw stud compatibility before starting a knockout.
• Use proper alignment to ensure clean cuts and minimize wear on the die edges.
• Apply suitable lubrication or cutting fluid as recommended for the material you are punching.
• Avoid using on hard alloys beyond the specified compatibility to protect the tool and workpiece.

Whether you are outfitting a new electrical run or upgrading a workshop toolkit, this AMZCNC punch and die offers practical capabilities for controlled, repeatable results with a focus on reliability and usability.
