Kay-Zee Knock-Out Punches are used to remove damaged micro vent inserts from the tire mold when insert replacement is necessary. These punches are manufactured from top quality tool steel with a special heat-treat and tempering process to resist breakage, while reducing peening of punch tip.

The most common size is 2.26mm (0.89") for 2.4mm (3/32") through hole.

Kay-Zee manufactures special Knock-Out Punches from 1.40mm (0.055") up to 3.2mm (0.125") diameter. We can supply many special sizes and lengths from stock. Kay-Zee can manufacture any diameter you may require within our size range.

The chart above shows the sizes and lengths that are currently manufactured and available from stock. Extreme sizes up to 18 inches long can be provided.

As shown in the picture above, the punch has a head attached. The proper method for using the punch is to have the punch shank approximately one half to one inch longer than the actual depth needed to reach the insert. This minimizes punch breakage.

KAY-ZEE SPRING VENT KNOCKOUT PUNCH

The standard knockout punch supplied by Kay-Zee Inc. has been modified to remove the center stem of a spring vent manufactured by Glebus. The tip of the punch is ground down to fit the inner diameter of the spring vent sleeve. When the spring vent is dirty and does not seal properly, it is necessary to remove the center stem. The vent sleeve can remain in place and be cleaned with the mold. Once the mold has been cleaned, the center stem can be re-inserted into the vent sleeve.

To identify the size of the spring vent knockout punch required, a Product Number is created as follows:

Series Number: 95

Diameter of Punch Rod: .090"/2.30mm is 090 .078"/2.00mm is 078

Overall Length of Punch Rod: 6" long is 60, 6-1/4" long is 61

As an example, a spring vent punch with rod diameter of .051"/1.30mm, length of 10-1/4" has a Product Number of 95051101.

Please note that there is a minimum order quantity of 5 for any spring vent punch.
