D Series Overview

Hole Punching Units for Thick Stainless Steel with Standard 8 3/8″ Shut Height and 3 1/2″ Die Height

“AJD” and “AHD” series punching units are specifically designed for punching holes in stainless steel from 1/8″ to 1/4″ thickness. Available holder widths are: 2”, 2 ½”, 3” and 3 ½”. Holder width is important because it defines the minimum hole to hole distance. This series comes standard with premium, wear-resistant tool steel designed to handle tough stainless steel punching applications. Depending on your material thickness, punch diameters are available from .2812” (7.14mm) to 1.500” (38.10mm). For more information on punching stainless steel, click here.

In addition to a wide range of standard round and shaped punches and dies, UniPunch provides punch and die pairs in shapes custom made to your specifications. Like most other series, the “A” series is available with holder throat depths of 4”, 8”, 12” and 18”, which means the center of the hole can be that distance from the edge of the sheet.

UniPunch units are rugged holders that allow you to punch burr-free holes with minimal maintenance. Various mounting methods are available including dedicated templates for fast changeover at the press.
