It is manufactured from solid carbide grade C2 and features a 135-degree split point with web thinning for fast penetration and reduced walking on entry. At 2.50 mm (0.0984 inch) in diameter, this short-series bit delivers superior rigidity compared to jobber-length equivalents, making it well suited for high-precision drilling in tight-tolerance work. A slow-spiral flute geometry supports chip evacuation in difficult-to-machine materials. The bright\/uncoated finish is standard for carbide tooling used across a broad range of ferrous workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in CNC machining centers, manual drill presses, and screw machine operations where a short, stiff cutting tool is required. Primary workpiece materials include cast iron, nickel alloy, stainless steel, titanium alloy, and tool steel. The straight cylindrical shank fits standard drill chucks and collet systems without modification. It is typically used by machinists and tool-and-die professionals working in production or maintenance environments where hole quality and tool life in hard materials are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide C2 grade construction for hardness and wear resistance in ferrous and exotic alloys\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust and eliminates center-punch requirements on most surfaces\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body provides maximum rigidity and minimizes deflection in deep-hole entries\u003c\/li\u003e\n  \u003cli\u003eSlow-spiral flute geometry promotes controlled chip flow in stainless steel, titanium, and nickel alloys\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains dimensional accuracy with a tight diameter tolerance of +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and ER collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a screw machine length replacement drill bit for applications requiring a 2.50 mm solid carbide stub-series bit with a straight shank, suitable for use in any machine tool or hand-held drill accepting a straight cylindrical shank in the 0.0000 to 0.1000 inch diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolroom technicians. Ensure the spindle is fully stopped and power is locked out before changing tooling in any drill press or machining center. Seat the shank fully in the chuck or collet and verify runout before cutting. Carbide tooling is brittle and should not be used in applications with significant side load or interrupted cuts without confirming material and setup suitability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 13\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Slow Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Nickel Alloy, Stainless Steel, Titanium Alloy, Tool Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSSC135-SS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 74148768\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741517283634,"sku":"74148768","price":19.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f6ba4fb6839d5b498e66540e71ab0b6.jpg?v=1788831984","url":"https:\/\/voomisupply.com\/products\/hertel-74148768-screw-machine-drill-bit-2-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
