Built to DIN 6537L and DIN 6535 standards, this bit features a 5.5 mm diameter, a 140-degree split-point (SU) geometry, and a titanium nitride (TiN) coating for extended wear resistance. The web-thinned, tapered web design reduces thrust force at entry. Coolant-through capability makes it suitable for deeper holes in production environments. The whistle notch shank provides positive rotational engagement in compatible holders. A licensed machinist or tool-and-die technician is the typical installer for this type of tooling.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in machining cast iron and steel workpieces where tight tolerances and clean entry are required. The 5xD flute-to-diameter ratio and 44 mm flute length support controlled chip evacuation in jobber-depth applications. The self-centering point geometry reduces the need for a center punch or spot drill on prepared surfaces. It is well suited for CNC machining centers and manual drill presses where a whistle notch or set-screw chuck retention is used. The 82 mm overall length fits standard jobber-length toolholders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and heat resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTitanium nitride (TiN) coating reduces friction and extends cutting tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point geometry for self-centering entry without pre-spotting\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing in deeper or higher-feed applications\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive engagement and resists pullout\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers thrust requirements at the drill tip\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537L and DIN 6535 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or direct-use drill bit for applications requiring a 5.5 mm diameter jobber-length carbide drill in the DIN 6537L form factor.

Secure the whistle notch shank firmly in a compatible holder before use — carbide is brittle and will fracture if run with excessive runout or lateral load. Confirm spindle speed and feed rate are appropriate for the workpiece material and drill diameter before engaging the cut. Do not use carbide drill bits in hand-held drills or flexible-shaft tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.5 mm (0.2165 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82 mm (3.228 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44 mm (1.732 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.75 mm (1.407 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 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\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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.004 to 0.016 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\u003eStandards\u003c\/strong\u003e: DIN 6537L, DIN 6535\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: 0.06 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: 9011830055000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727810822450,"sku":"9011830055000","price":253.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_c4abe607-ed4b-40a3-b027-cd96dca6351b.jpg?v=1788682813","url":"https:\/\/voomisupply.com\/products\/guhring-9011830055000-carbide-jobber-drill-bit-5-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
