With a 140-degree point angle and a 0.25-inch cutting diameter, it establishes accurate hole centers while minimizing walking and runout. The AlTiN coating extends tool life in demanding materials by improving heat resistance and surface hardness. At 2.5 inches overall length with a 0.75-inch flute length and a 0.25-inch straight cylindrical shank, this drill fits standard collet and chuck toolholding setups used in CNC machining centers and manual mills. It cuts right-hand and carries a Harvey Type II point geometry suited for general-purpose spotting work.\u003c\/p\u003e\u003cp\u003eThis spotting drill is intended for use in general-purpose machining applications across a wide range of workpiece materials including steel, stainless steel, aluminum, and cast iron. It is most commonly installed in CNC machining centers, turret mills, and drill presses where consistent hole location is critical before drilling, tapping, or reaming. The single-ended, two-flute spiral design supports efficient chip evacuation in short-depth spotting passes. Machinists and CNC operators in production shops, job shops, and toolrooms will find it suited to both prototype and production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e140-degree point angle centers holes accurately and reduces radial deflection at entry\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance beyond high-speed steel alternatives\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves thermal resistance for extended tool life in ferrous and high-temp alloy applications\u003c\/li\u003e\n\u003cli\u003eHarvey Type II point geometry designed for consistent spotting performance\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral flute design promotes chip clearance during spotting passes\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank seats directly in standard collets, ER chucks, or drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill compatible with standard 0.25-inch collet and drill chuck toolholding on CNC machining centers, turret mills, and drill presses.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this tool should be performed by a qualified machinist or CNC operator. Verify spindle and toolholder runout before use, as excessive runout will reduce tool life and hole location accuracy. Power down and lock out the machine spindle before changing or setting the tool in the holder. Spotting depth should be set to produce a chamfer diameter slightly larger than the following drill diameter to ensure proper drill entry — do not use this tool as a full-depth drill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Harvey Type II\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thickness\u003c\/strong\u003e: 0.018 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Spotting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Ended\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 41016-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51729423565106,"sku":"41016-C3","price":79.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3c14c9d72722f67d9a85b8993d12a2f.jpg?v=1788704446","url":"https:\/\/voomisupply.com\/products\/harvey-tool-41016-c3-spotting-drill-0-25-in-140-pt-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
