It measures 0.3425 inches (8.70 mm) in diameter with a 140-degree split point (SU type) that reduces thrust and improves centering at entry. The bit runs with two spiral flutes in a regular helix configuration and features a web-thinned, parallel-web construction that keeps chip evacuation efficient under load. Coolant-through capability makes this bit well suited for continuous-duty CNC machining cycles where heat management is critical. A straight-cylindrical shank seats directly in standard chucks and collets. Overall length is 3.50 inches (89.00 mm), with a flute length of 1.85 inches (47.00 mm) and a maximum drilling depth of 1.73 inches (44.00 mm).\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for cutting cast iron and steel in screw machine and CNC machining center applications. The screw machine length format provides a shorter, more rigid profile compared to jobber-length bits, which reduces deflection in high-feed, close-tolerance drilling operations. It is rated as a high-performance grade and conforms to DIN 6537 K standards, making it appropriate for production shops, job shops, and industrial maintenance operations where tight hole tolerances and consistent tool life are required. A licensed machinist or CNC operator would typically deploy this bit in a gang-drilling or turret-lathe setup.\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 reduces entry thrust and self-centers without a pilot\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed continuous drilling cycles\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned parallel web improves chip flow and reduces torque demand\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.006 to +0.021 mm for close-tolerance hole production\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537 K screw machine length drill bit for use in cast iron and steel workpieces.

Confirm coolant-through passages are clear and that coolant pressure is set to the machine and toolholder specification before initiating a cut. Do not exceed the recommended feed and speed parameters for the workpiece material — carbide is brittle and susceptible to chipping if subjected to interrupted cuts or excessive runout. Inspect shank and flutes for chips or damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3425 inches (8.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.50 inches (89.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.85 inches (47.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.73 inches (44.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.394 inches (10.00 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 (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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Submicron Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Coated\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\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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: 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: 0.2 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: 9055100087000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750210044210,"sku":"9055100087000","price":258.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_997cf692-0e89-408b-b97e-1fa84deb0869.jpg?v=1788914331","url":"https:\/\/voomisupply.com\/products\/guhring-9055100087000-screw-machine-drill-bit-0-3425in","provider":"Voomi Supply","version":"1.0","type":"link"}
