Built from high-speed steel with an oxide coating, this bit features a 135-degree split point that reduces walking and improves bite on entry without a center punch. The web-thinned, parallel-web construction reduces thrust and keeps the cutting action efficient. At 2.25 inches overall length, the stubby screw machine format provides rigidity and reduced deflection compared to jobber-length bits, making it well suited for drill press, CNC turret, and hand drill use in tight clearance situations. The straight cylindrical shank measures 0.2010 inches in diameter and fits standard chucks without adapters.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized to wire gauge number 7, with a decimal equivalent of 0.2010 inches. It is used in production machining, sheet metal work, and general fabrication where close-tolerance holes and stub rigidity are required. The screw machine length format is common on CNC turret presses and production drill fixtures where tool overhang must be minimized. The right-hand spiral flute evacuates chips efficiently during through-hole and blind-hole operations in ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e135-degree split point reduces walk on entry and lowers required thrust\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web construction for efficient chip clearance\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction with oxide coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eScrew machine length at 2.25 inches OAL delivers superior rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank at 0.2010 inches diameter fits standard 3-jaw chucks\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular spiral geometry for general-purpose drilling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard screw machine length drill bit for use in drill presses, CNC turret presses, and hand-held power drills equipped with chucks accepting a 0.2010-inch straight shank.

Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Verify spindle speed is appropriate for the material being drilled; excessive speed generates heat that shortens tool life on high-speed steel bits. Inspect the cutting edges and split point for wear or chipping before each use and replace the bit when performance degrades.\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: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2010 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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: 0.2010 inches\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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: 2386142\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747501343026,"sku":"2386142","price":38.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b99dc521c44b34979046ed897b24539.jpg?v=1788881443","url":"https:\/\/voomisupply.com\/products\/hertel-2386142-screw-machine-drill-bit-size-7-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
