With a 90-degree point angle and a cutting diameter of 0.0781 inches (5\/64 inches), it creates precise spot indentations that guide follow-up drill bits and reduce walking on difficult surfaces. The AlTiN coating extends tool life by improving heat resistance and surface hardness at elevated cutting temperatures. At 1.5 inches overall length with a 1\/8-inch straight cylindrical shank, it fits standard collets and chucks used in CNC machining centers and manual mills. Machinists and tool room operators install this drill in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis spotting drill is suited for general-purpose spotting and center-locating applications on ferrous and non-ferrous materials. The right-hand cutting direction and two-flute spiral flute geometry provide clean chip evacuation in short-depth spotting passes. It is well matched to CNC milling centers, drill presses, and manual machining setups where consistent hole location accuracy is required before reaming, tapping, or final drilling to size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in production cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves thermal resistance and extends tool life at higher surface speeds\u003c\/li\u003e\n  \u003cli\u003e90-degree point angle for accurate center spotting and chamfering\u003c\/li\u003e\n  \u003cli\u003eTwo-flute spiral geometry with 0.2344-inch flute length promotes chip clearance\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 1\/8-inch shank for compatibility with standard collets and chucks\u003c\/li\u003e\n  \u003cli\u003eHarvey Type I point geometry for repeatable, consistent spot depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose spotting drill for use in standard collet chucks and drill chucks accepting a 1\/8-inch straight cylindrical shank, compatible with CNC and manual machining setups requiring 90-degree spot geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the collet or chuck and verify runout before beginning the operation. Ensure the spindle is at a complete stop before tool changes.
