Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction compared to uncoated bits. The 135-degree split point starts on contact without a center punch, reducing walking on hard or smooth surfaces. At 1-13\/16 inches overall length, this stub-length geometry provides added rigidity in drill press, turret lathe, and CNC screw machine applications. Machinists and tool-and-die technicians working in high-cycle production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is sized at wire gauge number 40, which corresponds to 0.098 inch decimal diameter. The screw machine length format makes it well-suited for close-quarters drilling on automatic screw machines, turret lathes, and short-travel drill press setups. The straight-cylindrical shank fits standard Jacobs-style chucks and collet holders sized for 0.098 inch shanks. The right-hand spiral flute clears chips efficiently in typical through-hole and blind-hole operations on mild steel, aluminum, and thermoplastics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating increases surface hardness and lubricity for longer tool life in repetitive drilling cycles\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust force and eliminates center-punch requirement on flat stock\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, parallel web construction improves chip evacuation and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eStub screw machine length increases rigidity and reduces deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet tooling without modification\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation on all common machine tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or stock drill bit for screw machines, turret lathes, and drill presses accepting straight-shank tooling in the 0.098 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the chuck or collet is properly tightened before beginning any drilling operation. Do not exceed the rated speed for the workpiece material and bit diameter. Inspect the cutting edge and TiN coating for wear or chipping before each use; a damaged edge increases the risk of bit breakage and workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.098 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.8125 inches (1-13\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.8125 inches (13\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02387330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51746577482034,"sku":"02387330","price":56.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3372732f2da7d35aec5f21e0b0138ffe.jpg?v=1788871469","url":"https:\/\/voomisupply.com\/products\/hertel-02387330-screw-machine-drill-bit-size-40-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
