Built to a 90-degree point angle and measuring 3\/16 inches in cutting diameter, this single-ended tool delivers consistent spot depth and location accuracy on a wide range of workpiece materials. The AlTiN coating provides thermal resistance and hardness at elevated cutting temperatures, extending tool life in production environments. With a 4-inch overall length and a straight cylindrical shank, it seats securely in standard drill chucks and collet holders. This tool is suited for machinists, toolmakers, and CNC operators working in job shop and production settings.\u003c\/p\u003e\u003cp\u003eThe 55812-C3 is intended for general-purpose spotting and centering applications across ferrous and non-ferrous materials. The 5\/8-inch spiral flute length and 90-degree Harvey Type II point geometry provide clean entry without walking, making it a practical choice for precision hole location work on machining centers, drill presses, and manual mills. The right-hand cutting direction is standard for conventional spindle rotation setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree point angle for accurate drill spotting and chamfering in a single operation\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding cut conditions\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life at higher surface speeds\u003c\/li\u003e\n\u003cli\u003eHarvey Type II point geometry minimizes deflection and walking at entry\u003c\/li\u003e\n\u003cli\u003eSpiral flute design with 2 flutes promotes chip evacuation during spotting operations\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collet chucks and drill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill for use in standard drill chucks, ER collets, and similar straight-shank toolholding systems on CNC machining centers, drill presses, and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by machinists or CNC operators in a compatible straight-shank collet or chuck system. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after installation to confirm concentricity.
