Built from high-speed steel with an oxide coating, it is designed for general-purpose drilling in metal, wood, and plastics. The shorter-than-jobber overall length of 2-15\/16 inches provides added rigidity, reducing deflection in production and screw machine work. Two spiral flutes with a regular helix handle chip evacuation efficiently. This bit runs with a right-hand cutting direction and mounts in any standard straight-cylindrical shank chuck. It is installed and used by machinists, toolroom technicians, and maintenance trade professionals.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for benchtop drill presses, CNC drilling operations, turret lathes, and screw machine setups where a stubby, rigid bit is preferred over jobber length. The 3xD flute-to-diameter ratio and 1-11\/16-inch flute length make it appropriate for shallow-to-moderate depth holes in general-purpose shop applications. No coolant-through capability is present, so external coolant or cutting fluid should be applied at the cutting zone when drilling ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLetter O size with 0.3160-inch decimal equivalent for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle suitable for general-purpose drilling across common materials\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and heat resistance for production use\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and provides light corrosion resistance during storage and cutting\u003c\/li\u003e\n  \u003cli\u003eScrew machine length body (2-15\/16 inches OAL) delivers greater rigidity than jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with two spiral flutes and straight-cylindrical shank for universal chuck compatibility\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 standard drill press, lathe turret, or CNC spindle accepting a straight-cylindrical shank in the 0.316-inch diameter range.

Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before operation, and verify runout is within acceptable tolerance for the application. Power down and de-energize the machine spindle completely before inserting or removing the bit. When drilling ferrous metals without coolant-through capability, apply cutting fluid externally to extend tool life and manage heat buildup.\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\u003eOverall Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1-11\/16 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\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\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\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\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: 61699294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744595018034,"sku":"61699294","price":15.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6f125b24e1a88e0cc4979871b9989886.jpg?v=1788858779","url":"https:\/\/voomisupply.com\/products\/hertel-61699294-screw-machine-drill-bit-letter-o-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
