Built from micrograin solid carbide and coated with Ti-NAMITE-X, it delivers extended tool life and heat resistance in demanding applications. The bit measures 13.50 mm (0.5315 inches) in diameter with a 135-degree split point and an overall length of 107 mm (4.2126 inches). The web-thinned point reduces thrust and improves chip evacuation. Coolant-through capability supports high-speed operations where thermal management is critical. This bit is suited for machinists, toolroom technicians, and production drilling operators working with precision metal removal requirements.\u003c\/p\u003e\u003cp\u003eThe SGS 66494 is designed for universal workpiece materials, making it applicable across a wide range of ferrous and non-ferrous metals in manufacturing, job shop, and MRO settings. The screw machine length profile keeps the bit compact and rigid, which is well-suited for drill press, CNC machining center, and gang drilling operations where stub-length reach is preferred. The 2-flute spiral design with a regular helix promotes consistent chip flow throughout the 60 mm (2.3622 inch) flute length. The Series 142P designation identifies this as part of the SGS high-performance carbide drill family conforming to DIN 6537.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention in hard materials\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating provides enhanced wear resistance and lubricity\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed and deep-hole drilling cycles\u003c\/li\u003e\n\u003cli\u003e4-margin geometry improves hole finish and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance OEM-style replacement or new-installation drill bit for production drilling applications requiring a 13.50 mm screw machine length carbide bit with a straight-cylindrical shank.

Ensure the machine spindle and tool holder are clean and free of runout before seating the shank. Carbide tooling is brittle and should not be subjected to interrupted cuts or side loading beyond its rated geometry. Always verify coolant flow before initiating a drilling cycle when using the coolant-through feature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.50 mm (0.5315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 107 mm (4.2126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 60 mm (2.3622 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14.00 mm (0.6200 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm (1.7717 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 2.80 mm (0.1101 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Margins\u003c\/strong\u003e: 4\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard with Web Thinning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Micrograin Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.3622 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00028 to +0.00098 inches \/ +0.007 to +0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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: SGS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66494\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51755801870642,"sku":"66494","price":608.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bf50640ef89cd89e2915bdbf90a05e2.jpg?v=1788959841","url":"https:\/\/voomisupply.com\/products\/sgs-66494-screw-machine-drill-bit-13-50mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
