Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry and a Titanium Nitride (TiN) coating that extends tool life in abrasive materials. The whistle notch shank provides a positive, slip-resistant connection in compatible tool holders. At 91 mm overall length with a 53 mm flute length and a 5xD flute-to-diameter ratio, this bit handles moderate-depth through-hole and blind-hole applications in production and maintenance environments. Coolant-through capability supports high-speed drilling cycles where chip evacuation and heat management are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining cast iron and steel in CNC machining centers, drill presses, and manual machines equipped with whistle notch or precision round-shank toolholders. The self-centering SU point reduces the need for a pilot hole on flat or lightly curved surfaces, making it efficient for job shop, maintenance, repair, and production line drilling. It is sized at 19\/64 inches (0.2969 inches decimal) and is appropriate for machinists, toolroom technicians, and maintenance mechanics working with ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction for hardness and edge retention in cast iron and steel\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends cutting life in abrasive ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point is self-centering and reduces thrust force at entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal flood or mist coolant delivery for deep-hole applications\u003c\/li\u003e\n\u003cli\u003eWhistle notch shank provides positive drive and resists pullout in tool holders\u003c\/li\u003e\n\u003cli\u003eTapered web with web thinning improves chip flow and reduces walking\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting a 0.3150-inch diameter whistle notch shank per DIN 6535.

Secure the shank fully in a compatible whistle notch holder and verify runout before cutting. Carbide is brittle — avoid side loads, interrupted cuts without proper feed-rate management, and contact with hardened surfaces beyond the tool rating. Always power down and lock out the machine spindle before changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 19\/64 inches (0.2969 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: 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: 41.69 mm (1.641 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4961 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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\u003eSeries\u003c\/strong\u003e: 1183\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9011830075400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747780624690,"sku":"9011830075400","price":295.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_b28e891a-186a-4cbf-9a73-a4f68bf3727d.jpg?v=1788885393","url":"https:\/\/voomisupply.com\/products\/guhring-9011830075400-carbide-jobber-drill-bit-19-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
