Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in repetitive drilling operations. The 135-degree split point geometry provides fast penetration and self-centering entry without a center punch. At 27\/64 inch (0.4200 inch) diameter and 3-3\/8 inches overall length, this bit fits standard drill chucks and is well suited for use in drill presses, CNC machines, and hand-held power drills. Machinists, tool-and-die workers, and maintenance technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are shorter than jobber-length bits, giving them greater rigidity and reduced deflection in close-tolerance or production drilling environments. This bit is rated heavy duty grade, making it appropriate for ferrous metals, non-ferrous alloys, and plastics where consistent hole diameter and finish are required. The straight-cylindrical shank fits standard three-jaw chucks. The 2-inch flute length provides adequate chip clearance for the intended material range of 0.4000 to 0.4500 inch diameter hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e27\/64 inch (0.4200 inch) diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for fast self-centering penetration\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life in repetitive use\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction rated heavy duty grade\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (3-3\/8 inches OAL) provides added rigidity over jobber-length alternatives\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitution drill bit for applications requiring a 27\/64 inch straight-cylindrical shank screw machine length bit in standard three-jaw drill chucks and collet systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using standard drill press, lathe, or power tool setups. Secure the straight-cylindrical shank fully in the chuck before operation to prevent slippage. Power down and de-energize any machine tool before changing bits. Follow applicable shop safety standards and machine manufacturer guidelines for appropriate feed rate and spindle speed for the material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 27\/64 inch (0.4200 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2 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\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\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplicable Diameter Range\u003c\/strong\u003e: 0.4000 to 0.4500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 2386902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752398979378,"sku":"2386902","price":23.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f2758dc53a16b0b524f774cb911f0d7.jpg?v=1788927921","url":"https:\/\/voomisupply.com\/products\/hertel-2386902-screw-machine-drill-bit-27-64-in-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
