Manufactured from high-speed steel with a bright\/uncoated finish, it features a 90-degree included angle and a 1\/4-inch straight cylindrical shank. The head diameter measures 3\/8 inches and overall length is 2 inches. No pilot is included, and the tip nose diameter is 0.090 inches. This tool is suited for machinists, tool-and-die technicians, and fabricators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis countersink is built for use on alloy steel, mild steel, stainless steel, cast iron, high-tensile steel, high-nickel steel, Monel, aluminum, brass, magnesium, magnesium alloy, and plastic. The 90-degree angle makes it appropriate for standard fastener seat preparation and edge chamfering on drilled holes across both manual and CNC machine setups. Its straight cylindrical shank fits standard collets and drill chucks commonly found in machining centers, drill presses, and hand-held power tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree included angle for standard fastener countersink geometry\u003c\/li\u003e\n  \u003cli\u003e6-flute design provides smooth cutting action and improved chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction supports use across ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose machining applications\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch straight cylindrical shank fits standard collets and chucks\u003c\/li\u003e\n  \u003cli\u003eSingle-end, no-pilot design for direct chuck mounting without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose countersink compatible with standard 1\/4-inch collets and drill chucks on manual drill presses, machining centers, and CNC equipment.
