Our knockouts are compatible with a range of standard knockout sizes, from ½" to 6" conduit sizes (please refer to chart in catalog for actual hole diameters). 

Yes, our knockouts use industry-standard thread sizes and are compatible with most commonly used punches and die sets. However, for best performance and fit, we recommend using Current Tools punches and dies.

We offer a variety of knockout sets from manual, drill driven, and hydraulic.   For example, the hydraulic set comes with a hydraulic hand pump, ram, hose, and punch and dies.  Each set is packed in a durable carrying case. Specific contents vary by model, so check product details on the website or in the catalog for exact configurations.

A knockout punch is designed to create a clean, round hole by removing the core material, often used in sheet metalwork for blanking or piercing, leaving a smooth hole without excess burrs. A stud punch, on the other hand, creates a smaller, precise hole specifically sized for inserting a stud, bolt, or fastener, commonly used in automotive or machinery fabrication for secure fastening.

A manual knockout is operated by hand, providing a more hands-on approach but requiring more physical effort, typically used for lighter or less frequent punching tasks.

A hydraulic knockout utilizes hydraulic pressure to apply force, making it ideal for thicker materials or high-volume work, as it requires less manual effort and can generate more force.  A drill-driven knockout uses a power drill to drive the punch through the material, offering speed and precision for creating holes quickly.
