It measures 7 mm (0.2756 inches) in diameter with an overall length of 91 mm and a flute length of 53 mm. The 140-degree split point (SU-style) geometry is self-centering, reducing the need for a center punch on most materials. A titanium nitride (TiN) coating increases surface hardness and extends tool life in production drilling applications. The two-flute, regular spiral design promotes chip evacuation in both cast iron and steel workpieces. This bit is suited for CNC machining centers, drill presses, and manual machines equipped for whistle notch tooling.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for drilling cast iron and steel in industrial and precision machining environments. The 5xD flute-to-diameter ratio and 42.50 mm maximum drilling depth make it well matched to through-hole and moderate-depth drilling operations on ferrous materials. The web-thinned, tapered web design reduces thrust force at the cutting tip. It is commonly used in job shops, maintenance machining, and production facilities where dimensional accuracy and tool longevity are priorities. The whistle notch shank provides secure seating in collet and machine tool holders designed for that shank style.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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 point is self-centering and reduces required thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole heat management\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web reduces cutting resistance at drill entry\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 machine tool holders and collet systems that accept a whistle notch shank with a 0.3150-inch shank diameter, conforming to DIN 6535.

Power down and lock out the machine before installing or removing the bit from the holder. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper feed adjustments, and impact during handling or storage. Verify that the spindle speed and feed rate are set to values appropriate for 7 mm carbide in the target material before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7 mm (0.2756 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: 42.50 mm (1.673 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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eStandards\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: 9011830070000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730920177970,"sku":"9011830070000","price":294.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_8b8ac14e-ff40-4852-85d7-0c82a1c90258.jpg?v=1788724796","url":"https:\/\/voomisupply.com\/products\/guhring-9011830070000-carbide-jobber-drill-bit-7mm","provider":"Voomi Supply","version":"1.0","type":"link"}
