You're punching hundreds of sheets a week — you need a punch that won't slow you down. The Carl HD530N handles 300 sheets of 80gsm paper in one go, with a self-centering gauge that lines up your pages dead straight every time. Double-sided gauge lets you switch between 2-hole and 4-hole punching, and the rotary action blade keeps mess to a minimum. Built for the heavy lifting in busy NZ offices and print shops.
