Built to DIN 6537 K standards, this bit features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The 3.10 mm (0.122 inch) diameter, two-flute spiral design delivers precise, repeatable holes in cast iron and steel. Coolant-through capability supports high-speed production environments where heat management is critical. Licensed HVAC, plumbing, and mechanical contractors as well as machinists and tool-room professionals use this type of bit where tight tolerances and tool life are priorities.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and screw machine applications where a compact flute length and rigid solid carbide construction are required. The straight-cylindrical shank measures 6.00 mm in diameter, making it compatible with standard collet chucks and drill chucks used in production and maintenance machining. Primary workpiece materials include cast iron and steel, making this bit well-suited for HVAC equipment fabrication, mechanical panel work, and precision component drilling in trade-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron grade construction for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning reduces entry thrust and walking\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and deep-hole drilling cycles\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with parallel web configuration for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eCoated finish improves wear resistance and surface lubricity\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537 K specification for dimensional accuracy and performance consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance OEM-style solid carbide drill bit for screw machine length applications in cast iron and steel workpieces, conforming to DIN 6537 K standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with carbide tooling. Before mounting, power down and lock out the machine spindle per applicable safety procedures. Solid carbide tooling is brittle — avoid side loading, interrupted cuts without proper feed rates, or dropping the bit on hard surfaces. Verify collet or chuck runout is within acceptable limits before use to prevent premature tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.122 inches (3.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 62.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 20.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 18.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\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\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 Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eWeight\u003c\/strong\u003e: 0.04 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: 9055100031000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727229485362,"sku":"9055100031000","price":159.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_446c1e8c-f7a7-4452-978f-17f84f3aa139.jpg?v=1788675040","url":"https:\/\/voomisupply.com\/products\/guhring-9055100031000-screw-machine-drill-bit-0-122in","provider":"Voomi Supply","version":"1.0","type":"link"}
