Built from high-speed steel with an oxide coating, it runs a 135-degree split point that reduces walking and lowers thrust at entry. The web-thinned, parallel-web construction keeps cutting resistance low across the full depth of the hole. At 2.8125 inches overall length, the stub-length profile provides added rigidity over jobber-length bits, making it a common choice in screw machine and CNC turret applications where chatter and deflection must be controlled. Licensed trades and machinist shops are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis bit fits residential and commercial manufacturing and maintenance environments where tight-tolerance, repeatable holes are required. The straight-cylindrical shank seats directly in standard drill chucks and collet holders without adapters. Its heavy-duty grade and NAS 907 specification make it appropriate for production line use, fixture drilling, and maintenance shops running automatic or semi-automatic drilling equipment. The right-hand spiral flute clears chips efficiently in through-hole applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter N size: 0.3020 inches decimal diameter for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces center-punch dependency and lowers entry thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web design minimizes cutting resistance and heat buildup\u003c\/li\u003e\n  \u003cli\u003eOxide coating provides lubricity and basic corrosion resistance during storage and use\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.8125 inches OAL increases rigidity versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eMeets NAS 907 specification for heavy-duty drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement in any standard drill chuck or collet accepting a 0.3020-inch straight-cylindrical shank, consistent with NAS 907 screw machine length drill bit requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstalled by machinists, maintenance technicians, and tool-and-die professionals using standard drill presses, screw machines, or CNC turret equipment. Secure the shank fully in the chuck or collet and verify runout before beginning a production run. Power down or de-energize the spindle completely before changing or inspecting bits. Do not exceed the recommended feed and speed parameters for the workpiece material, as overfeeding a stub-length bit in hard stock can cause premature edge failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\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\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: 0.3020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\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\u003eSpecification Number\u003c\/strong\u003e: NAS 907\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: NAS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 83238824\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749689458994,"sku":"83238824","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/693954151c6ee495671e115ea41a7bdf.jpg?v=1788909246","url":"https:\/\/voomisupply.com\/products\/hertel-83238824-screw-machine-drill-bit-letter-n-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
