We pioneered a process for manufacturing precision milling cutters without form grinding after heat treat. This gives our customers the benefits of ground quality tools without the loss of usable life normally seen in ground cutters.
Star SU offers ultra-precision ground rack cutters with pitch accuracies of less than 5μm and tools over 200 mm long with special chip breaker designs.


Star SU provides unparalleled quality for multiple pitched form relieved milling cutters from standard rack forms to asymmetrical shapes. Metric or inch dimensions up to 300mm long. We offer you a high quality, competitive cost and delivery alternative as a manufacturer of Rack Milling Cutters made to your specific manufacturing needs.

Features
Applications
Special form cutters are available in a range of configurations including:

Available in shell type or shank type, multiple thread milling cutters are form relieved and can be supplied with special thread forms.
Two Basic Designs:
Multiple thread milling cutters are of two basic designs, shell type and shank type. Both types are form relieved and may be sharpened by grinding the straight or spiral gash of the cutter, without changing their forms. Both types can be supplied with special thread forms, as well as standard straight, taper or pipe threads, to cut internal and external threads.
Star SU delivers world-class gear cutting tools, advanced coating technologies, and engineering expertise that help manufacturers improve precision, productivity, and performance.
