It features a 100-degree point angle, a 0.25-inch cutting diameter, and a 2.5-inch overall length. The AlTiN coating increases surface hardness and heat resistance, making it well suited for cutting harder workpiece materials at elevated speeds. With a Harvey Type II point geometry and right-hand spiral flutes, it produces consistent spot locations that reduce drill walk and improve hole accuracy across a variety of materials and setups.\u003c\/p\u003e\u003cp\u003eThis spotting drill is used in general-purpose machining environments, including job shops, production floors, and tool rooms. It is a single-ended tool intended for use in CNC machining centers, mill-drill setups, and manual milling machines. The straight cylindrical shank fits standard drill chucks and collet holders with a 0.25-inch bore. It is appropriate for spotting operations on steel, stainless, aluminum, and similar engineering materials where precise hole location is required before drilling or tapping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e100-degree point angle for accurate spotting before full drill engagement\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eHarvey Type II point geometry reduces lateral deflection at drill entry\u003c\/li\u003e\n\u003cli\u003eTwo-flute right-hand spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank for compatibility with standard collet and chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style spotting drill for use in standard 0.25-inch collet holders, ER collet chucks, or drill chucks in CNC and manual milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is properly seated and torqued before engaging the spindle. Verify runout with a dial indicator when precise hole location is critical.
