Built to DIN 6537 K standards, this bit features a 0.2874-inch diameter, a 140-degree split point (SU type), and a web-thinned, parallel web configuration that reduces entry force and improves chip evacuation. The straight-cylindrical shank measures 8.00 millimeters in diameter and seats securely in standard drill chucks and collet holders. With a regular spiral flute geometry and right-hand cut, it delivers consistent, controlled material removal. Machinists, tool-and-die workers, and maintenance technicians working with ferrous metals rely on this series for accuracy and tool life.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for primary workpiece materials including cast iron and steel, making it well suited for production drilling, fixture work, and precision hole-making in job shop and manufacturing environments. The screw machine length format provides a shorter, stiffer profile compared to jobber-length bits, reducing deflection in tight setups or on CNC machining centers. The coated finish further supports tool longevity in abrasive or high-cycle applications. Maximum drilling depth is 1.183 inches (30.05 mm), and the flute-to-diameter ratio is 3xD, consistent with Series 5514 geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning reduces thrust force and self-centers on entry\u003c\/li\u003e\n\u003cli\u003eScrew machine length (shorter flute) minimizes deflection in tight or high-precision setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip removal in cast iron and steel\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 8.00 mm shank fits standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6537 K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a Series 5514 screw machine length carbide drill bit for use in standard drill chucks, collet holders, and CNC tool holders accepting an 8.00 mm straight-cylindrical shank. Suitable for drilling cast iron and steel workpieces within the 0.2500- to 0.3000-inch drill bit size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or maintenance technicians familiar with cutting tool setup and machine operation. Ensure the machine spindle is fully stopped and de-energized before loading or changing tooling. Verify shank seating and runout before beginning a drilling cycle, as excessive runout accelerates carbide wear and can cause breakage. Coolant-through is not supported on this bit; external coolant or cutting fluid application is recommended when drilling steel at elevated feed and speed rates.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2874 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 (Split Point)\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: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.183 inches (30.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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: No\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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.006 to +0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5514\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: 0.08 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: 9055140073000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729310384434,"sku":"9055140073000","price":166.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1722d1467d4ba478bd1f6fe04876cc3d_41d4d455-e421-4fd2-bcf7-0cf075f8bbc8.jpg?v=1788702745","url":"https:\/\/voomisupply.com\/products\/guhring-9055140073000-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
