Circular Chaser System

Here's how RSVP's Circular Chaser System offers the longest tool life over all other threading systems.

Circular Chaser shape allows for the chaser to be ground through a full 270 degrees.
Shape of the cutter permits minimal rubbing action immediately behind the cutting edge to ensure proper lead control eliminating excessive rubbing for smoother threads and longer chaser life.
Chasers body mass and external mounting provides a faster dissipation of heat away from the work, frees chips for faster cutting speeds, and allows for the ability to cut up close to the shoulder of a part.
Replaceable plunger wear groove inserts extend the life of the cutting head.

This system is designed for maximum tool usage and life that allows for increased productivity which saves you more money.
