Dottie HPD78 7/8" Die for 1/2" Conduit

Get faster, cleaner conduit punches and reduce downtime with the Dottie HPD78 7/8 in die for 1/2 in conduit. This replacement die is built from high-speed alloy steel to withstand continuous use on both steel and stainless applications, delivering the durability installers rely on for security, surveillance and low-voltage wiring. The HPD78’s 3-point die geometry eliminates slug binding in the cup for consistent hole quality, while laser-etched centering lines and size ID speed alignment and reduce installation errors. Because the die requires up to 50% less torque than competitive designs, crews experience less fatigue and use less force from punch tools — translating to faster installs and fewer tool replacements. Interchangeability with other brands’ cups and punch tools makes the HPD78 an easy upgrade for technicians working across networking, monitoring and CCTV conduit runs. Ideal for professional electricians, security integrators and AV technicians who demand reliable, repeatable conduit holes. Add the Dottie HPD78 to your toolbox for smoother, more efficient conduit adapter and cable-routing installations.
