CHASERS AND ROLLS FOR ASSEMBLED THREADED TOOLS
Milled Type Radial Chasers for Geometric and H & G Die Heads
Milled thread chasers are available in standard and special thread forms. These thread forms are milled prior to heat treat with the blank finish ground to extremely close tolerances after hardening. Milled thread chasers, when used with the recommended die head, will cut a class 3A thread.
Ground Thread Radial Chasers for Geometric and H & G Die Heads
Ground thread chasers are available in standard and many special thread forms. The blanks are heat treated and precision ground before creep feed thread grinding. Creep feed grinding produces an exceptional micro-finish on the chaser threads.
Geometric supermetric chasers are all ground thread, held to precision tolerances.
Tapped Form (Concave Profile) Radial Chasers for Geometric Die Heads
Tapped form chasers are milled with a concave thread profile then heat treated. The blank is then precision ground. The concave thread profile gives added support to the chasers when cutting. All tapped form chasers have fully eccentric thread profiles.
Geometric Tangent Chasers
All elements on the Geometric tangent, including thread forms, are fully ground. Tangent chasers allow multiple regrinds for production applications.
“S” Chasers for Geometric Taps
All Geometric “S” chasers are ground after heat treat. Thread profiles are convex and manufactured with different radial clearances depending upon material to be threaded.
Vers-O-Tool Circular Chasers
The circular chasers are designed for production jobs, or jobs that repeat frequently. All circular chasers have crush ground threads. Circular chasers allow for multiple regrinds.
Acme Fette Thread Rolls
All Acme Fette thread rolls have crush ground threads, from hardened blanks. The first thread is ground as a partial to aid in the initial material deformation; this also increases the thread roll life. All Acme Fette rolls are reversible.
