B Series Overview

Low Profile Hole Punching Units with Standard 5 1/2″ Shut Height and 2 19/32″ Die Height

“B” series punching units are ideal for lighter duty punching applications and for press environments with limited opening. Available “B” series holder widths are: 3/4”, 1 1/4”, 1 3/4”, 2 1/4”, 3” and 5”. Holder width is important because it defines the minimum hole to hole distance. The “B” series is widely used in industry to punch mild steel up to 10 gauge in thickness. Depending on your material thickness, punch diameters are available from .0937” (2.38mm) to 3.500” (88.90mm). (For thicker punching applications, see the “A” series.)

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 “B” series is available with holder throat depths of 4”, 8”, and 12”, 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.
