Built to DIN 6537K standards, this 15\/64 inch (0.2344 inch) diameter bit features a 140-degree split point with SU geometry and web thinning for reduced thrust and self-centering entry. The straight-cylindrical shank measures 6.00 mm in diameter, and the overall length is 66.00 mm. Coolant-through capability makes it suitable for high-speed production environments where heat management is critical. Licensed machinists, tool-and-die workers, and CNC operators are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for cutting cast iron and steel in screw machine length applications, where a shorter flute-to-diameter ratio of 3xD keeps the tool rigid and reduces deflection. The regular spiral flute with parallel web configuration channels chips efficiently during through-hole and blind-hole operations. A maximum drilling depth of 25.00 mm suits typical production drilling cycles on CNC machining centers, drill presses, and screw machines running in right-hand rotation. The coated carbide substrate extends tool life in abrasive ferrous workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction for wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU point with web thinning reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed and high-feed production drilling\u003c\/li\u003e\n\u003cli\u003eScrew machine length body (3xD flute ratio) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck toolholding\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537K specification for consistent dimensional tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for right-hand rotation CNC machining centers, screw machines, and drill presses requiring a 15\/64 inch diameter screw machine length carbide drill bit.

Secure the straight-cylindrical shank in a properly sized collet or drill chuck to the toolholder manufacturer's specified clamping torque range. Verify coolant-through passages are clear before initiating a cutting cycle. Handling carbide tooling requires care to avoid chipping the cutting edges during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Fractional)\u003c\/strong\u003e: 15\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.2344 inches\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\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, Regular\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 Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 25.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 9055100059500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728529162546,"sku":"9055100059500","price":195.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_47aad7e1-df61-44aa-97cc-8f95ad281110.jpg?v=1788692784","url":"https:\/\/voomisupply.com\/products\/guhring-9055100059500-screw-machine-drill-bit-15-64","provider":"Voomi Supply","version":"1.0","type":"link"}
