It features a 1-inch cutting diameter, a 3.5-inch length of cut, and a 6-inch overall length, making it well suited for deep-reach profiling and slotting applications. The micrograin carbide construction provides hardness and edge retention at elevated cutting speeds. A ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC tooling professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills requiring a 1-inch shank. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action during peripheral and slot milling. The centercutting geometry allows plunge entry directly into the workpiece. With a right-hand cut and right-hand spiral flute configuration, it is compatible with standard spindle rotation on most milling equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch cutting diameter with a mill diameter tolerance of +0.000 \/ -0.002 inches\u003c\/li\u003e\n\u003cli\u003e3.5-inch length of cut for extended reach profiling and deep slot milling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eZrN coating reduces friction and improves tool life across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003e45-degree spiral helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC and manual mill spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 1-inch shank square end mill for use in milling machines and machining centers that accept 1-inch toolholders, collet chucks, or end mill holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator.
