With a 3\/4 inch cutting diameter and an 82-degree drill point angle, it produces a precise center spot that keeps follow-up drills on target without wandering. The overall length is 5.1875 inches, making it a compact, rigid tool suited for CNC machining centers, manual mills, and drill press setups. Machinists, toolroom operators, and production floor personnel are the primary users of this tool in both job-shop and production environments.\u003c\/p\u003e\u003cp\u003eThis spotting drill is suited for general-purpose spotting and chamfering operations on metals and engineered materials in ferrous and non-ferrous applications. The cobalt M-42 substrate offers increased heat resistance compared to standard high-speed steel, making it appropriate for harder workpiece materials or situations where cutting speeds run higher. It is a single-ended tool with a straight cylindrical shank, compatible with standard drill chucks and collet holders accepting a 3\/4 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree point angle for accurate spot location and compatibility with standard drill point geometry\u003c\/li\u003e\n\u003cli\u003eCobalt M-42 construction provides improved red-hardness and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e3\/4 inch cutting diameter with matching 3\/4 inch straight cylindrical shank for secure chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003e1.5 inch flute length with 2-flute spiral design at a 20-degree helix angle for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish — no coating buildup to affect dimensional tolerances at the point\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, single-ended tool for standard spindle rotation setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose spotting drill for use in standard drill chucks and collet holders with a 3\/4 inch bore.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the straight cylindrical shank firmly in a drill chuck or collet holder to the appropriate clamping torque per the toolholder manufacturer. Verify spindle speed and feed rate are appropriate for the workpiece material before beginning the spotting operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 82 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eHelix Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt M-42\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle\/Double Ended\u003c\/strong\u003e: Single\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: 0.6534 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: Y59918920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744661274930,"sku":"Y59918920","price":99.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a7ddb6fa737b098ca4f1d1193ec0496.jpg?v=1788859702","url":"https:\/\/voomisupply.com\/products\/hertel-y59918920-spotting-drill-3-4in-82pt-cobalt-m-42","provider":"Voomi Supply","version":"1.0","type":"link"}
