It features a 1\/4 inch diameter, a 0.50 mm (0.0200 inch) corner radius, and five flutes arranged in a variable-pitch configuration. The APLUS PVD coating improves wear resistance and surface finish across a broad range of metalworking applications. At 4 inches overall length with a 2-1\/8 inch reach, this tool is built for extended-reach operations without sacrificing rigidity. It is single-end, centercutting, and right-hand cutting with a right-hand spiral flute direction, making it suitable for both roughing and finishing passes in a single setup.\u003c\/p\u003e\n\u003cp\u003eThe 35137 is engineered for use in CNC machining centers and manual mills where tight tolerances and consistent corner geometry are required. Its extended reach of 2-1\/8 inches makes it well-suited for deep-pocket milling, cavity work, and contoured surfaces in low-alloy steel, medium alloy steel, tool steel, and cast iron as primary workpiece materials. Stainless steel, superalloys, and titanium are listed as secondary material applications. The variable pitch eliminates harmonic chatter common in demanding cuts, and the APLUS coating supports higher cutting speeds in abrasive materials. High-precision toolholders are recommended to take full advantage of the 0.0005 inch maximum TIR specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and long tool life in ferrous and hard materials\u003c\/li\u003e\n  \u003cli\u003eAPLUS PVD coating rated for steel, cast iron, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eVariable pitch design reduces chatter during aggressive roughing and finishing passes\u003c\/li\u003e\n  \u003cli\u003e0.50 mm corner radius with a tight tolerance of -0.0020 to 0.0020 inches\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 2-1\/8 inches enables deep-pocket and cavity milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with high-precision toolholders.
