With a 0.21-inch cutter head diameter and a 90-degree included angle, this tool produces a 0.037-inch chamfer width in a single pass. The 5-flute geometry improves chip evacuation and surface finish quality. An AlTiN coating adds heat resistance and extends tool life in ferrous and hard alloy materials. A licensed machinist or CNC operator typically installs and runs this tool on vertical machining centers or manual mills.\u003c\/p\u003e\n\u003cp\u003eThis back chamfer cutter is suited for precision machining operations where access to the back face of a feature is required without repositioning the workpiece. The 0.13-inch neck diameter allows reach into tight clearance areas, while the 0.25-inch shank provides a standard collet-compatible interface. Typical applications include cross-hole deburring, countersink blending, and edge prep on aerospace, automotive, and general metalworking components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.21-inch cutter head diameter with 0.037-inch chamfer width at 90 degrees\u003c\/li\u003e\n  \u003cli\u003e5-flute solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance and improved performance in ferrous alloys\u003c\/li\u003e\n  \u003cli\u003e0.13-inch neck diameter enables reach into confined back-face locations\u003c\/li\u003e\n  \u003cli\u003e0.25-inch shank diameter fits standard ER and precision collet toolholders\u003c\/li\u003e\n  \u003cli\u003e2.5-inch overall length suits most VMC and manual mill spindle clearances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification back chamfer cutter compatible with standard 0.25-inch collet toolholders on CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator.
