Built from high-speed steel with an oxide coating, this bit is designed for short-reach, high-precision drilling applications where rigidity and reduced deflection are critical. The stubby screw machine length profile makes it well suited for drill press work, CNC drilling operations, and benchtop setups where a standard-length bit would flex or chatter. The split point geometry enables fast penetration with minimal walking, and the oxide finish provides a modest increase in lubricity and surface hardness.\u003c\/p\u003e\n\u003cp\u003eThis bit is used in metalworking, light fabrication, and production drilling environments. It is appropriate for drilling steel, aluminum, brass, and similar materials in applications requiring tight hole placement and consistent diameter. The straight-cylindrical shank seats in standard drill chucks without the need for specialized toolholding. At 1.75 inches overall length with a 0.75 inch flute length, it fits compact setups and is commonly used by machinists, tool and die workers, and precision fabricators working in the 0.0000 to 0.1000 inch drill size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 47 at 0.0785 inches decimal diameter for precise small-hole drilling\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning reduces thrust force and eliminates center punching on most metals\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length body maximizes rigidity and minimizes deflection in short-reach setups\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for improved surface hardness and lubricity\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet systems without modification\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit screw machine length drill bit for any standard drill chuck or collet accepting a 0.0785 inch straight-cylindrical shank, compatible with drill presses, CNC drilling machines, and benchtop power tools across the 0.0000 to 0.1000 inch drill size range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed machinist or qualified fabricator should secure the bit firmly in the chuck or collet before operation, verifying no runout before engaging the workpiece. Power down and de-energize the machine before inserting or removing bits. Use appropriate cutting fluid for ferrous materials to extend tool life. Do not exceed the recommended feed and speed parameters for high-speed steel tooling in the given workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 47\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0785 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\u003eShank Diameter\u003c\/strong\u003e: 0.0785 inches\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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.0000 to 0.1000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 2386548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738306412850,"sku":"2386548","price":34.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a752b533d31d167f672ca25f88499ac3.jpg?v=1788798015","url":"https:\/\/voomisupply.com\/products\/hertel-2386548-screw-machine-drill-bit-size-47-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
