A Series Overview

Hole Punching Units with Standard 8 3/8″ Shut Height and 3 1/2″ Die Height

“A” series punching units are the workhorse of the UniPunch product line. Available “A” series holder widths are: 1”, 1 ¼”, 1 ½”, 2”, 2 ½”, 3 ½”, 5 ½” and 8”. Holder width is important because it defines the minimum hole to hole distance. The “A” series is widely used in industry to punch mild steel up to 1/4″ thickness. Depending on your material thickness, punch diameters are available from .0937” (2.38mm) to 5.000” (127mm). This series can punch up to a 3 ½”diameter hole in 1/4″ mild steel and up to a 5” diameter hole in 10 ga. mild steel. (For thicker punching applications, see the “AH” and “AD” series.)

Dedicated Setups of UniPunch tooling.

UniPunch “A” series holders up to 2” wide feature economical two-piece punches. The punch heads and bodies are separate which lets you quickly change hole size or shape by simply changing the inexpensive punch body and the die. The unique slip-on retainer pin holds the punch in place without any special tools. You can use and reuse the punch heads indefinitely. Low-cost die buttons complete the punch system and offer close tolerances for accuracy and interchangeability.

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.
