It measures 21\/64 inches (0.3281 inches) in diameter with an overall length of 103 mm and a flute length of 61 mm. The 140-degree split point geometry reduces walking and thrust force at entry. A Titanium Nitride (TiN) coating increases surface hardness and extends tool life in high-cycle production environments. This bit is installed by machinists and metalworking tradespeople in CNC machining centers, drill presses, and manual mills where tight tolerances and consistent performance are required.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in ferrous and non-ferrous metals, alloys, and similar hard materials where a carbide substrate outperforms high-speed steel. The whistle notch shank provides positive drive engagement and resists pullout in collet and chuck setups. The 5xD flute-to-diameter ratio and regular spiral flute design support efficient chip evacuation at higher feed rates. Its coolant-through capability makes it compatible with through-spindle coolant systems, reducing heat buildup and extending tool life in deep-hole drilling applications. Typical applications include production machining and precision fabrication work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade substrate for high hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eTiN coating for extended tool life and reduced friction in metal cutting\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with web-thinned, SU-style tip reduces entry thrust and walking\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eWhistle notch shank provides positive drive engagement and pullout resistance\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification jobber length drill bit conforming to DIN 6537L standards, suitable for use in CNC machining centers, drill presses, and manual mills equipped with collet or chuck toolholding systems that accept a 0.3937-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling technicians familiar with cutting tool safety practices. Before changing or setting this bit, ensure the spindle is fully stopped and the machine is in a locked-out or de-energized state per applicable shop safety procedures. Verify collet or chuck clamping torque is appropriate for the shank diameter and tool weight before initiating a cut. When using coolant-through capability, confirm the spindle and toolholder are rated for through-spindle coolant delivery before pressurizing the coolant system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 21\/64 inches (0.3281 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\u003eOverall Length\u003c\/strong\u003e: 103 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 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\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003ePoint Type\u003c\/strong\u003e: SU Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Whistle Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eSpecification\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: 9011830083300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739076624690,"sku":"9011830083300","price":351.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ddff9395fe8773e92b2e14cb487240a_96f5befd-ea4f-4a32-a85a-1d702e8c6eb9.jpg?v=1788808999","url":"https:\/\/voomisupply.com\/products\/guhring-9011830083300-carbide-jobber-drill-bit-21-64","provider":"Voomi Supply","version":"1.0","type":"link"}
