Built from high-speed steel with an oxide coating, it runs a standard 118-degree point angle and a straight-cylindrical shank for use in conventional drill chucks and machine spindles. At 2.6875 inches overall length, the shortened flute geometry reduces deflection and improves rigidity compared to jobber-length bits. The two-flute spiral design clears chips efficiently during through-hole and blind-hole work. This bit is sized at Letter I, equivalent to 0.272 inches in decimal, and follows ANSI specification. Machinists, maintenance technicians, and metalworking professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eScrew machine length drill bits are used in turret lathes, drill presses, CNC machining centers, and handheld power drills where a shorter, stiffer bit reduces chatter and improves hole accuracy. The 3xD flute-to-diameter ratio makes this bit well suited for shallow to moderate-depth holes in general-purpose production environments. The right-hand cutting direction is standard for conventional clockwise-rotation spindles. The oxide finish provides mild corrosion resistance and reduces friction during the cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter I size (0.272 inches decimal) following ANSI specification designation\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle for general-purpose drilling in a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for reduced friction and light corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 2.6875 inches OAL for increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003e1.5-inch flute length with 3xD flute-to-diameter ratio for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and machine tool holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with any drill chuck or machine spindle accepting a straight-cylindrical shank in the 0.272-inch bit diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and serviced by machinists and maintenance technicians. Secure the shank fully in the chuck or collet before operation and confirm the spindle is at a full stop before bit changes. Use appropriate cutting fluid for ferrous metals to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and discard bits that show signs of material fatigue.\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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.272 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.6875 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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\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: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 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: 61698973\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51754695328050,"sku":"61698973","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1dd73e1d8a083b586752a43f0cc42ce5.jpg?v=1788947911","url":"https:\/\/voomisupply.com\/products\/hertel-61698973-screw-machine-drill-bit-letter-i-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
