The shorter flute length of the screw machine format provides added rigidity and reduced deflection compared to jobber-length bits, making it well suited for drill press and CNC machining applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this bit runs at standard speeds for HSS tooling. The 118-degree split-point angle is a conventional general-purpose geometry that self-centers on flat stock and works across a wide range of workpiece materials. Overall length is 2-15\/16 inches.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is used in production machining, machine shops, maintenance and repair operations, and tool rooms where screw machine length bits are specified for short, controlled drilling passes. The Letter O size (0.3160 inches) is commonly used for tapping and clearance hole preparation in light to medium-duty applications. It is appropriate for use in manual drill presses, turret lathes, screw machines, and CNC turning or machining centers. Licensed machinists and maintenance technicians are the primary installers and users of this tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter O size — 0.3160 inches decimal equivalent, within the 0.3000 to 0.3500 inch size range\u003c\/li\u003e\n  \u003cli\u003e118-degree conventional point angle for general-purpose drilling across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2-15\/16 inches OAL provides increased rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction suitable for standard drilling speeds\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish for general-purpose grade applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, standard for most drilling operations\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 standard drill chucks, collets, and tool holders accepting straight-shank bits in the Letter O (0.3160 inch) size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tooling is installed and operated by machinists and maintenance technicians using drill presses, lathes, or CNC machining centers. Secure the straight shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Use appropriate cutting fluid for the workpiece material to extend tool life. Follow shop-specific feeds and speeds for high-speed steel tooling to avoid overheating and premature wear.\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: O\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.3160 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.3000 to 0.3500 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\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 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: 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\u003eDrill Bit Grade\u003c\/strong\u003e: General Purpose\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\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: 89321160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727837823282,"sku":"89321160","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d5a0b187db38657172d0a417693e473.jpg?v=1788683278","url":"https:\/\/voomisupply.com\/products\/hertel-89321160-drill-bit-letter-o-118-point-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
