Built to a 140-degree point angle, it establishes accurate hole location and reduces walking before full-diameter drill engagement. The 2-flute spiral geometry provides clean chip evacuation, and the AlTiN coating improves heat resistance and extends tool life in ferrous and abrasive materials. With a cutting diameter of 0.07 inches and an overall length of 1.5 inches, this tool suits tight-tolerance work in machining, fabrication, and production environments. It is installed and operated by machinists and CNC operators working with drill presses, machining centers, and CNC mills.\u003c\/p\u003e\u003cp\u003eThis spotting drill is suited for general-purpose applications requiring accurate hole positioning before drilling, countersinking, or tapping. The straight cylindrical shank at 0.125 inches diameter fits standard collet chucks and drill chucks commonly used in CNC and manual machining setups. The 0.21-inch flute length is optimized for shallow spotting passes rather than deep-hole drilling. Typical use cases include production machining on steel, stainless steel, cast iron, and other hard materials where the AlTiN finish provides thermal stability at elevated cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e140-degree point angle for accurate hole location and reduced drill walk\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous applications\u003c\/li\u003e\n\u003cli\u003e2-flute spiral geometry for efficient chip evacuation during spotting passes\u003c\/li\u003e\n\u003cli\u003eHarvey Type I point geometry designed for precise spotting\u003c\/li\u003e\n\u003cli\u003eSingle-ended, right-hand cutting direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill compatible with standard straight-cylindrical collet chucks and drill chucks accepting a 0.125-inch shank diameter on CNC machining centers, drill presses, and manual mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Ensure the spindle is fully stopped and machine is powered down or in a safe state before changing tooling. Secure the shank firmly in the collet or chuck to the manufacturer-recommended clamping depth to prevent runout. Use appropriate cutting fluid or dry cutting per material requirements; do not force the tool beyond its rated flute length engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.07 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\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Harvey Type I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thickness\u003c\/strong\u003e: 0.005 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\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: 39870-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51728010477874,"sku":"39870-C3","price":61.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d9baac008b2792f440eb9aa7a82f9fd_f6ceab5a-4df8-4e78-a27b-53598813b481.jpg?v=1788686102","url":"https:\/\/voomisupply.com\/products\/harvey-tool-39870-c3-spotting-drill-0-07-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
