THREAD MILLS

Solid Carbide Thread Mill without Coolant Hole Solid Carbide Thread Mill with Coolant Hole Solid Carbide Thread Mill with Coolant Hole & Chamfer Solid Carbide Miniature Thread Mill Solid Carbide Drill and Thread Mill

Much higher productivity, much more improved thread surface finish than tapping. Advantages of Thread Milling includes “higher cutting speeds and feeds than tapping”, "making smaller and easier to remove chips than taps", and "multiple function with one tool - both right/left hand threads and blind/through holes". Also applicable to hardened materials and exotic materials with predictable production. Expansion of thread mill operation range to "drill and thread mill with chamfer" and "thread mill with chamfer/internal coolant" series.
