Manufactured to DIN 6537 L and DIN 6535 standards, it measures 118 mm (4.646 inches) in overall length with a 71 mm (2.795 inches) flute length. The submicron carbide substrate provides the hardness and wear resistance required for productive drilling in ferrous materials. A whistle notch shank secures the bit positively in the holder and resists rotation under cutting loads. This bit is installed by machinists and toolroom technicians working on production drilling operations in CNC machining centers or drill presses.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for drilling cast iron and steel in industrial and manufacturing environments. The self-centering 140-degree point geometry reduces the need for a center punch on flat stock. The 5xD flute-to-diameter ratio accommodates moderate-depth holes, and the coolant-through design channels fluid directly to the cutting edge for heat management and chip evacuation in deeper applications. It is suited to production environments where consistent hole quality and extended tool life in P and K workpiece material categories are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for high wear resistance in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point geometry with web thinning for self-centering entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design directs fluid to the cutting zone for heat and chip control\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank prevents rotation and slip under heavy feed loads\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 L and DIN 6535 standards for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders and collet chucks that accept a 0.4724-inch shank diameter with a whistle notch seat.

Before mounting, confirm the toolholder bore matches the 0.4724-inch shank diameter and that the whistle notch setscrew aligns correctly with the flat. Ensure the machine spindle is fully stopped and locked before inserting or removing the bit. When using the coolant-through feature, verify that coolant pressure and flow rate are within the machine spindle specifications to avoid damage to internal channels.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 29\/64 inches (0.4531 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\u003eOverall Length\u003c\/strong\u003e: 118 mm (4.646 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 mm (2.795 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.116 inches (53.74 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4724 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8504 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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: 0.007 to 0.025 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 L, DIN 6535\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1183\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 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: 9011830115100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737523224882,"sku":"9011830115100","price":493.82,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_71edbfdd-56d2-415d-af6d-3c08edcc65da.jpg?v=1788789735","url":"https:\/\/voomisupply.com\/products\/guhring-9011830115100-carbide-drill-bit-29-64-in-140-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
