Built from high-speed steel with an oxide coating, this bit carries a wire gauge size 43 designation, equivalent to 0.0890 inches in decimal form. The 135-degree split point reduces walking and allows the bit to start on contact without a center punch in many setups. At 1.75 inches overall length, the stub-length body delivers added rigidity compared to jobber-length bits, making it well-suited for CNC machines, drill presses, and screw machines where chatter and deflection need to be minimized. A right-hand spiral flute clears chips efficiently during the cut.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in production machining environments, tool rooms, and general metalworking shops. The screw machine length format fits standard drill chucks and collet holders on benchtop and floor-standing equipment. It is commonly used when drilling through steel, aluminum, brass, and similar materials where a short, stiff bit improves hole accuracy and finish. The web-thinned, parallel-web construction reduces thrust force at the point, which is particularly useful when drilling smaller-diameter holes at higher feed rates. Licensed machinists, tool-and-die technicians, and CNC operators are the primary users of this bit type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 43, 0.0890 inches decimal diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003e135-degree split point starts on contact and reduces drill walking\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for wear resistance and lubricity\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 1.75 inches OAL for added rigidity and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web design lowers cutting thrust and extends bit life\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute promotes efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit with a straight cylindrical shank at 0.0890 inches, compatible with drill chucks and collet systems sized for wire gauge drill blanks in that diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall this bit in a properly sized drill chuck or collet and confirm the shank is fully seated and the chuck is tightened before operation. Machinists should verify spindle speed and feed rate settings appropriate for the workpiece material and bit diameter prior to drilling. Use cutting fluid or coolant as appropriate for the material being drilled, noting that this bit does not support coolant-through delivery. Inspect the cutting edges for wear or chipping regularly, as small-diameter bits at this size range are susceptible to breakage if run at incorrect speeds or with excessive side loading.\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: 43\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 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: Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 2386506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737731596594,"sku":"2386506","price":34.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6858d4272bee8e6421ff2e05d0ff28d2.jpg?v=1788792926","url":"https:\/\/voomisupply.com\/products\/hertel-2386506-screw-machine-drill-bit-size-43-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
