Built to DIN 6537L standards, this bit features a 140-degree split point (SU-style) with web thinning for self-centering entry without a center punch. The Titanium Nitride (TiN) coating extends tool life by reducing friction and heat buildup at the cutting edge. At 5.4 mm in diameter and 82 mm overall length, it fits standard jobber-length applications where consistent hole quality and dimensional accuracy are critical. Submicron carbide grade construction resists wear in demanding production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron and steel workpieces in both production shop and field maintenance settings. The whistle notch shank provides positive retention in compatible chucks and tool holders. The 5xD flute-to-diameter ratio and 44 mm flute length support chip evacuation in through-hole and moderate-depth drilling cycles. Coolant-through capability allows internal coolant delivery when used with appropriate spindle tooling, making it a practical choice for CNC machining centers and manual drill presses where tool life and hole tolerance are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for self-centering entry\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and improves wear resistance\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with internal coolant spindle setups\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank for secure chuck retention per DIN 6535\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Ensure the spindle and workpiece are secured before engaging the cut. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the spindle system. Inspect the cutting edge and TiN coating for wear regularly, as carbide tooling can chip if subjected to intermittent cuts without proper feed-rate control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.4 mm (0.2126 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.90 mm (1.413 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 inch\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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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: 0.004 to 0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1183\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\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: 9011830054000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51744605339954,"sku":"9011830054000","price":256.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cbae5699708142d77b5e5800ead3b3d6_7ea427f9-f432-489a-909f-c97206adcb66.jpg?v=1788858907","url":"https:\/\/voomisupply.com\/products\/guhring-9011830054000-carbide-jobber-drill-bit-5-4mm","provider":"Voomi Supply","version":"1.0","type":"link"}
