Countersink Punch & Die Sets

Eliminate secondary operations and PUNCH accurate and repeatable countersinks. By using Whitney's bottoming tooling, each countersink is the correct depth, and is concentric to the hole.

A typical countersink is produced via a two-step operation. First, an oversize pilot diameter is punched. This is followed by using a countersink tool that cold-forms the final shape of the countersink.

Formed countersinks in sheet metal are possible in a single hit. Contact Whitney with your application.

Plow Bolts Plow bolts are used for single side assembly when it is not practical to use a wrench on both sides of a hole. The appropriate hole is a countersunk hole with a square pilot. This is performed by using the countersink procedure, followed by a third tool, a square punch.
