It features a 140-degree point angle, a 1\/8 inch cutting diameter, and an AlTiN (aluminum titanium nitride) coating that improves heat resistance and extends tool life in demanding materials. The overall length is 1.5 inches with a 3\/8 inch flute length, making it a compact, rigid tool suited for tight setups. Two spiral flutes with a right-hand cutting direction provide efficient chip evacuation. This drill is intended for use by machinists and tool-and-die professionals in CNC and manual machining environments.\u003c\/p\u003e\u003cp\u003eThis spotting drill is applicable to general-purpose machining operations where accurate hole location is required before drilling, countersinking, or threading. The 140-degree point angle matches common twist drill geometries, reducing walk and improving positional accuracy. The straight cylindrical shank with a 1\/8 inch diameter fits standard collets and drill chucks. Typical applications include production shops, tool rooms, and job shops working with steel, aluminum, stainless, and similar machinable materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e140-degree Harvey Type I point for accurate hole spotting and reduced drill walk\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for improved thermal resistance and extended tool life in ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eTwo spiral flutes with right-hand cutting direction for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard collets and drill chucks\u003c\/li\u003e\n\u003cli\u003eCompact 1.5 inch overall length suited for close-clearance and short-reach setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide spotting drill for use in standard collet chucks and drill chuck toolholders accepting a 1\/8 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with CNC or manual milling and drilling equipment. Ensure the machine spindle is fully stopped and the tool holder is properly cleaned and torqued before securing the shank. Confirm collet or chuck bore size matches the 1\/8 inch shank diameter before mounting. Follow the machine manufacturer and tooling manufacturer guidelines for speed and feed selection appropriate to the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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\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\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\/Finish\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thickness\u003c\/strong\u003e: 0.010 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: 39925-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51744775504178,"sku":"39925-C3","price":58.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d9baac008b2792f440eb9aa7a82f9fd_407384f8-7bb8-4a27-af3e-351f9024b07b.jpg?v=1788860380","url":"https:\/\/voomisupply.com\/products\/harvey-tool-39925-c3-spotting-drill-1-8-in-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
