Need Large Diameter Taps?

or Extended Length Taps?

When we say large diameter, we are talking about taps that are 1 1/2″ (M36) in diameter to taps that are 4″ (M100) in diameter.

Taps these large can be 10″-12″ (or more) in length.  That’s a significant amount of steel!

For our customers to receive what they want, Jarvis has developed entire skill set to support these tools. These tools are not ordered in large quantities, so we have a variety of equipment that can productively produce lots of three to five pieces (or more).
