Built to DIN 6537 L standards, it features a 140-degree split point (SU) geometry with web thinning for self-centering entry without a pilot hole. The titanium nitride (TiN) coating increases surface hardness and extends tool life in abrasive materials. At 7.3 mm in diameter with a 91 mm overall length and a 53 mm flute length, this bit is suited for applications requiring tight tolerances. Coolant-through capability supports deep-hole operations and chip evacuation at elevated feeds and speeds.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for cast iron and steel workpiece materials, making it a reliable choice for machining shops, maintenance facilities, and production lines where ferrous materials are machined regularly. The whistle notch shank provides a secure grip in compatible toolholders and reduces slippage under load. Its 5xD flute-to-diameter ratio and regular spiral flute design support consistent chip flow in through-hole and blind-hole applications. The submicron carbide grade delivers the hardness and edge retention needed for high-volume drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardness and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating extends tool life and reduces built-up edge\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning enables self-centering without spot drilling\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling up to 42.05 mm depth\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank prevents rotational slippage in toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with toolholders accepting a 0.3150 inch shank diameter with a whistle notch interface.

Ensure the machine spindle and toolholder are clean and free of chips before seating the shank. Confirm coolant lines are clear and pressure is set before engaging coolant-through drilling cycles. Do not exceed the rated maximum drilling depth of 42.05 mm without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.3 mm (0.2874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 42.05 mm (1.656 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.006 to 0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1183\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6535, DIN 6537 L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9011830073000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727727165746,"sku":"9011830073000","price":295.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_96423f6f-5bf4-4d53-ac6f-54a70edcb50e.jpg?v=1788681323","url":"https:\/\/voomisupply.com\/products\/guhring-9011830073000-carbide-drill-bit-7-3-mm-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
