Screw machine length bits feature a shorter overall length compared to jobber-length bits, which increases rigidity and reduces deflection in high-cycle production drilling, CNC machining, and turret lathe work. This bit is ground from high-speed steel with a bright, uncoated finish and a standard 118-degree split-point angle suitable for general-purpose drilling in mild steel, aluminum, plastics, and similar materials. The overall length is 2.25 inches with a flute length of 1.1875 inches.\u003c\/p\u003e\n\u003cp\u003eThis bit is well suited for production shops, machine shops, and maintenance applications where short-length rigidity is preferred over reach. The No. 9 wire gauge size falls in the 0.1500 to 0.2000 inch decimal range, making it a common size for clearance holes, tapping pilots, and close-tolerance bore work. Machinists, tool-and-die makers, and maintenance mechanics typically reach for screw machine length bits when working in confined setups or when chatter and wandering are concerns at low feed rates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge No. 9 diameter — 0.1960 inches decimal equivalent\u003c\/li\u003e\n  \u003cli\u003e118-degree conventional point angle for general-purpose drilling\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles standard cutting speeds in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for general purpose use without coating wear concerns\u003c\/li\u003e\n  \u003cli\u003eShort screw machine length (2.25 inches OAL) increases rigidity and reduces deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, compatible with standard drill press and CNC spindle rotation\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 fitting standard three-jaw drill chucks and collet systems that accept the shank diameter corresponding to a No. 9 wire gauge bit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall in a properly sized drill chuck or collet and verify secure seating before operating. Ensure the spindle speed is appropriate for the workpiece material and bit diameter — consult published speeds-and-feeds references for high-speed steel in the target material. Secure the workpiece firmly before drilling to prevent rotation or movement. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows visible damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1960 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: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.1875 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\u003eDecimal Size Range\u003c\/strong\u003e: 0.1500 to 0.2000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0195 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: 89321897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750750781746,"sku":"89321897","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a8543274e198c98b20da596d808e6aa.jpg?v=1788919346","url":"https:\/\/voomisupply.com\/products\/hertel-89321897-screw-machine-drill-bit-no-9-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
