Standard Shapes
The shapes below are UniPunch standards. When ordering, specify the dimensions you require, the angular orientation, and the holder in which you will use the punches and dies. UniPunch will key the punches and dies to fit the holders with which you will use them. Refer to individual holder specifications for the maximum punch diameters. Metric sizes are available.

Point “X” refers to the position on the shape as illustrated and is used to communicate the desired orientation.
S=Diameter, P=Perimeter *Sketch required

Required Dimensioning Specifications

The shapes shown here require additional dimension information when ordering.

Front of Unit Orientation Information
For most UniPunch holders, shaped punches and dies can be used in two positions at 90 degrees to each other, typically at 0° and 90°, 45° and 135°, 180° and 270°, and so on. 0° is at the front of the holder, and the angular rotation is clockwise when viewed from the top. Keying at other than 90° is also available.

The keyhole shape as shown in the drawing, when ordered would specify point ‘X’ at 180 and 270 degrees.

Heeled Punches are recommended for notching the edge of a sheet. The heel of the punch projects into the die to stabilize the punch.

Note: Use edge notch units for high production and heavy material applications or when notch is beyond the range of Heeled Punches.
