Niagara Cutter has launched a new portfolio of solid-carbide thread mills that bring strength and process reliability to a broad range of general purpose machining applications. Overall, the portfolio comprises thread mills for the cost-effective, highly accurate production of Unified, National Pipe Tapered, and metric thread forms. With a vast selection of thread sizes, cutting diameters, cutting lengths, shank diameters, and more, shops have well over 100 different tooling options from which to choose. All of the Niagara thread mills feature a standard AlCrN coating and are available with optional coatings of TiN, TiCN, TiAIN, AlTiN, and CVD-diamond.
Niagara UN thread mills are ideal for flat-bottom holes and large-diameter applications where torque and horsepower requirements for taps are not available. Offered in standard, coolant-through, and extended-reach options, these helical flute thread mills offer positive cutting action and are suitable for both internal and external operations.
The standard Niagara TM100UN thread mill comes in a full range of industry-standard thread sizes with cutting diameters from 0.065" to 0.62" and cutting lengths between 0.125" and 1.375". The coolant-through TM120UN thread mill comes in various thread sizes with cutter diameters from 0.134" to 0.62" and cutting lengths between 0.313" and 1.375". The extended-reach TM160UN comes in a variety of thread sizes with cutter diameters from 0.134" to 0.62" and cutting lengths between 0.1" and 0.375".
