The full-profile thread mills in this product line improve on the basic MTS thread mills, by adding a coolant bore, and either 1 or 2 coolant holes. By providing a high-pressure stream of coolant fluid through the bore, we can wash the chips away from the thread during the cutting cycle – improving tool performance, and providing superior thread accuracy. An additional benefit is the efficient cooling of the tool’s cutting edge. Features: Supports threads as small as ISO M1.2 x 0.25, and 0-80 UNF The thread depth can be up to 4 x Thread Diameter (for some tools) Multi (3-4) flutes Suitable for high-speed air turbine machines (30,000-40,000 RPM), and for standard machining centers (6,000+ RPM) Recommended Usage: Thread milling operations in horizontal machining centers, especially cases where the chips are concentrated at the buttom of the thread, and external coolant can’t wash them away. Complicated applications, when the external coolant is inefficient, or can’t reach the machined area Cases where the tool collet is too close to the application pre-hole, which causes it to block the external coolant Carbide Grade: MT7 Sub-micron grade with multi-layer TiAIN coating. This is a general purpose grade, which can be used with all materials. (ISO K10-K20)
