The most recent addition to the expanded Niagara Cutter Stabilizer product family, the ST540 5-flute endmill enhances performance and versatility. The STS540, STSN540, STR540, STRN540 and STRCS540 family of solid-carbide endmills offers complete solutions for machining processes ranging from slot milling to side mill finishing, as well as those involving up to 40% radial stepovers for fast material removal thanks to strong cutting edges and full eccentric reliefs.

In addition to smaller diameter tools for high-performance milling and 140 new inch sizes, including a new necked version for long-reach applications, the expansion also includes advanced helical chip splitters developed by Niagara Cutter to ensure good chip evacuation in even the most challenging applications. An innovative offset design ensures fine surface finishes and makes for an all-in-one endmill that can handle both roughing and finishing operations and is equally effective in all material types, from steel to cast iron and stainless steels to superalloys.
