Built to DIN 6537K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The straight-cylindrical shank seats securely in standard drill chucks and collets. At 0.2874 inches (7.30 mm) in diameter with a 3xD flute-to-diameter ratio, it is suited for shops and field work where short, rigid tooling is required. Coolant-through design supports extended tool life in production environments. Two spiral flutes provide efficient chip evacuation in ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis bit is intended for machining cast iron and steel in screw machine, CNC, and manual drilling operations where a compact, stub-length drill is preferred for rigidity. The screw machine length body reduces deflection in short-reach setups and in applications where hole depth is limited. Maximum drilling depth is 38.00 mm (approximately 1.50 inches). The Series 5510 designation places this within a high-performance carbide drill line manufactured to tight diameter tolerances of plus 0.006 to plus 0.021 mm.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for hardness and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design extends tool life in continuous or high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eDIN 6537K compliant with parallel web configuration for consistent geometry\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard collets and drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, 2-flute configuration for reliable chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Secure the shank fully in the collet or chuck to the manufacturer-recommended engagement depth before operation. Ensure the machine spindle is fully stopped before loading or removing the bit. When using the coolant-through feature, confirm coolant supply lines are connected and pressurized to the machine specification before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2874 inches (7.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (approximately 3.11 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm (approximately 1.61 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 38.00 mm (approximately 1.50 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (approximately 0.315 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: 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: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.006 to plus 0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5510\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 9055100073000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738288881970,"sku":"9055100073000","price":217.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_533351f2-e17b-43c0-930d-0a51adb41685.jpg?v=1788797763","url":"https:\/\/voomisupply.com\/products\/guhring-9055100073000-screw-machine-drill-bit-0-2874in","provider":"Voomi Supply","version":"1.0","type":"link"}
