The shortened overall length of 1-15\/16 inches compared to jobber-length bits provides increased rigidity and reduced deflection, making it well suited for drilling in tight clearances or on manual drill presses and screw machines. Ground from high-speed steel with a bright uncoated finish, this bit features a 118-degree split point angle and a right-hand cutting direction. The 9\/64-inch diameter measures 0.1406 inches in decimal. It is a standard single-piece unit used by machinists and maintenance technicians alike.\u003c\/p\u003e\u003cp\u003eScrew machine length drill bits are commonly used in production machining environments, toolroom operations, and general maintenance applications where stub-length rigidity is preferred over the reach of a standard jobber bit. The 9\/64-inch size fits typical work involving small-diameter through-holes, pilot holes, and clearance holes in sheet metal or light structural stock. This bit installs directly into any compatible chuck or collet system sized for its shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9\/64-inch (0.1406 inches) diameter for precise small-hole drilling\u003c\/li\u003e\n\u003cli\u003e118-degree point angle provides a standard, versatile cutting geometry\u003c\/li\u003e\n\u003cli\u003eScrew machine length body at 1-15\/16 inches OAL reduces deflection in short-reach applications\u003c\/li\u003e\n\u003cli\u003e15\/16-inch flute length allows efficient chip evacuation for the drill depth range\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles general-purpose drilling across common work materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suits standard machining environments without added coating cost\u003c\/li\u003e\n\u003cli\u003eRight-hand cut for use with conventional forward-rotating drill chucks and screw machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose screw machine length drill bit compatible with any drill press, hand drill, or screw machine chuck sized to accept the 9\/64-inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified maintenance technician should secure this bit firmly in a properly sized chuck or collet before operation. Ensure the drill press or machine spindle is powered off and at a complete stop before changing bits. Use appropriate cutting fluid for metal drilling to extend tool life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows signs of damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9\/64 inches (0.1406 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-15\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15\/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\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: 0.06 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: 89321491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730039636274,"sku":"89321491","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7f2567ae273d6b5e35eacbbd06a4564.jpg?v=1788710604","url":"https:\/\/voomisupply.com\/products\/hertel-89321491-screw-machine-drill-bit-9-64-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
