With a 1\/8 inch diameter, a 1\/2 inch length of cut, and a 0.02 inch corner radius, this tool produces smooth, radiused edges while reducing corner chipping and stress concentration at the cutting edge. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. At 1-1\/2 inches overall length with a 1\/8 inch shank, this end mill fits standard collet toolholding systems. It is single-end, centercutting, and intended for use by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is well suited to finishing passes in slot milling, profile milling, and contouring where a controlled corner radius is required on the workpiece. The right-hand spiral flute geometry and 40-degree helix promote efficient chip evacuation and smooth cutting action. The bright uncoated finish makes it a practical choice for non-ferrous metals, aluminum, and general-purpose machining where coating is not required. Its compact diameter makes it appropriate for detail work, small-feature machining, and tight-radius contouring on CNC mills and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003e0.02 inch corner radius reduces edge chipping and workpiece stress concentration\u003c\/li\u003e\n  \u003cli\u003e40-degree helix with right-hand spiral flutes for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for non-ferrous and general-purpose materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end configuration with 1\/8 inch shank for standard collet compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC mills and machining centers with standard 1\/8 inch collet or toolholding systems.
