Dottie HPD400 4" Die for 3-1/2" Conduit

Quick, reliable conduit punching for security, surveillance, and low-voltage installations starts with the Dottie HPD400 die. This 4" die sized for 3-1/2" conduit is engineered from high speed alloy steel to deliver long service life and consistent, clean cuts when used with Dottie hole punch tools. Installers benefit from a 3-point die design that eliminates slug binding and a laser-etched cup with centering lines for fast alignment and fewer reworks. Dual-rated construction handles both steel and stainless steel, reducing the need to swap tools across mixed-material runs typical in networking, IT cabling, and physical security deployments. Requiring up to 50% less torque than competing dies, the HPD400 lowers operator effort and speeds throughput on repetitive punching tasks. Interchangeability with other leading brands adds flexibility on the jobsite and simplifies inventory for contractors and systems integrators. For dependable, fast conduit punching on security, monitoring, and data cabling projects, add the Dottie HPD400 die to your toolkit—order now or pair it with Dottie punch tools for immediate use.
