Built from high speed steel, it delivers the edge retention and hardness required for production and maintenance machining environments. The 1-1\/2 inch head diameter and 82-degree included angle make it well suited for creating seat geometry for flat-head fasteners. The 3\/4 inch straight cylindrical shank mounts directly into standard drill chucks or collet holders without adapters. Machinists, toolroom technicians, and maintenance trades rely on this style of countersink for fast, repeatable fastener prep on ferrous and non-ferrous stock.\u003c\/p\u003e\n\u003cp\u003eThis countersink is appropriate for use in vertical machining centers, drill presses, and hand-held drilling equipment where the spindle accepts a 3\/4 inch straight shank. The 82-degree angle conforms to the standard seat geometry for inch-series flat-head machine screws and aerospace-style flush fasteners. The single-flute design reduces chatter and produces a smooth, burr-free seat finish. It is commonly used in metal fabrication shops, maintenance and repair operations, and general manufacturing environments where consistent countersink geometry is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2 inch head diameter for large-diameter countersink seats\u003c\/li\u003e\n  \u003cli\u003e82-degree included angle conforms to inch-series flat-head fastener standards\u003c\/li\u003e\n  \u003cli\u003eSingle-flute design minimizes chatter and produces smooth seat finish\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides edge retention across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch straight cylindrical shank fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style single-flute countersink for use in drill presses, machining centers, and portable drilling equipment accepting a 3\/4 inch straight cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMount the shank securely in a drill chuck or collet holder rated for the shank diameter before operation. Ensure the spindle is fully stopped and power is isolated before installing or removing the tool.
