Built to DIN 6537 K standards, it features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The two-flute spiral design and coolant-through capability make it well suited for high-speed machining operations where heat and chip evacuation are critical. At 11.50 mm (0.4528 inches) in diameter, it carries a tight diameter tolerance of +0.007 to +0.025 mm, supporting consistent hole quality across production runs. Licensed machinists and toolroom technicians typically specify this bit for CNC and conventional drilling applications.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for cutting cast iron and steel workpieces in screw machine and general production drilling setups. The straight-cylindrical shank at 12.00 mm diameter seats securely in standard drill chucks and collet holders. The screw machine length format — shorter overall length for rigidity — is preferred in high-cycle production settings where deflection and runout must be minimized. The 3xD flute-to-diameter ratio and 55.00 mm flute length support chip clearance at depths up to 52.00 mm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU point with web thinning reduces entry thrust and walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, deep-hole drilling\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance (+0.007 to +0.025 mm) for consistent bore sizing\u003c\/li\u003e\n\u003cli\u003eDIN 6537 K compliant for use in standardized tooling systems\u003c\/li\u003e\n\u003cli\u003eSubmicron carbide grade for improved edge retention and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for screw machine length drill applications in cast iron and steel.

Ensure the straight-cylindrical shank is fully seated and torqued in the chuck or collet holder before operation. Coolant-through setups require confirming spindle coolant supply compatibility before running. Inspect the cutting edges for chipping or wear before each use and replace the bit if edge integrity is compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11.50 mm (0.4528 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 102.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 55.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 52.00 mm\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel (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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 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\u003eSeries\u003c\/strong\u003e: 5510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 9055100115000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727127675186,"sku":"9055100115000","price":351.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_ff7a026b-0d7d-46b1-bfd1-20ce2169cd8c.jpg?v=1788673798","url":"https:\/\/voomisupply.com\/products\/guhring-9055100115000-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
