Screw machine length bits are shorter than jobber length, giving them added rigidity for accurate starting and reduced deflection in production drilling, turret lathe, and drill press applications. The bright uncoated finish keeps the surface as-ground with no additional coating, making it a reliable general-purpose option for drilling steel, aluminum, cast iron, and similar common materials. Right-hand cut, 118-degree split or standard point geometry suits a wide range of through-hole and blind-hole drilling tasks encountered daily in machine shops and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis bit is suited to general-purpose drilling in both production and maintenance settings. The shorter overall length of 2.6875 inches and 1.5-inch flute length make it well-matched to screw machine turrets, CNC lathes, drill presses, and handheld power drills where stub-length tooling provides better control. It is a practical choice for machinists, maintenance technicians, and fabricators working with ferrous and non-ferrous metals, plastics, and composite materials in light-to-medium duty operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter I size — 0.2720 inch decimal equivalent for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree point angle for general-purpose drilling across a broad range of materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides hardness and heat resistance for metal drilling\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length adds rigidity and reduces deflection compared to jobber length bits\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating to chip or peel, consistent performance out of the box\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry compatible with standard drill chucks and turret tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit fitting standard drill chucks and turret holders that accept round-shank tooling in the 0.2500 to 0.3000 inch decimal inch size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSecure the bit firmly in a properly sized drill chuck or turret holder before operation and verify runout before drilling critical-tolerance holes. Use appropriate cutting fluid or coolant when drilling steel or cast iron to extend tool life and improve hole finish. Inspect the cutting edges for wear or chipping before each use and regrind or replace the bit when point geometry is degraded. Follow shop safety procedures including eye protection and secure workpiece fixturing at all times.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.2720 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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 Bit Grade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2500 to 0.3000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: 89320980\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751149732146,"sku":"89320980","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d0097b00e5c64d4ca67e33fb1c3b7fe.jpg?v=1788921901","url":"https:\/\/voomisupply.com\/products\/hertel-89320980-drill-bit-letter-i-0-272-in-118-deg-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
