Featuring a 7\/32 inch (0.2188 inches) diameter and a 137-degree split point, this bit delivers accurate hole entry with reduced thrust. The 2-flute regular spiral design and web-thinned geometry promote efficient chip evacuation in short-flute, close-clearance applications. With a straight cylindrical shank and a 2.5984-inch overall length, it fits standard drill chucks and CNC setups. It is installed by machinists, toolroom technicians, and precision metalworking trades working in production or maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66408 is suited for screw machine, drill press, and CNC machining center applications where stub-length rigidity is required. The short flute length of 0.9449 inches limits deflection in tight setups and thin-section workpieces. The DIN 6537 specification and micrograin carbide substrate support consistent performance across universal workpiece materials including ferrous and non-ferrous metals. Coolant-through capability makes this bit compatible with high-speed production drilling operations where heat management is critical. It is a Series 142P tool sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003e7\/32 inch (0.2188 inches) diameter with a tight tolerance of +0.00016 to +0.00063 inches\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length at 2.5984 inches OAL for maximum rigidity in confined setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned point geometry reduces thrust and improves hole entry accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n  \u003cli\u003e4-margin straight cylindrical shank compatible with standard and precision drill chucks\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production cutting tool for use in standard drill chucks, collet holders, and CNC spindles accepting a straight cylindrical shank in the 5.9995mm shank diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists or toolroom personnel with the machine powered down and all spindle rotation stopped. Secure the straight shank fully within the chuck or collet holder to the specified grip depth before operation. Ensure coolant-through channels are clear and compatible with the machine tool coolant system before engaging high-speed feeds. Follow applicable shop safety procedures and tool manufacturer feed-and-speed recommendations for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7\/32 inch (0.2188 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5984 inches (65.9994 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.9449 inches (24.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (35.999 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.9995 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0310 inches (0.79 mm)\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\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated (Proprietary)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9449 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00016 to +0.00063 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eTool Performance Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: SGS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51750649823538,"sku":"66408","price":208.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40bbeb29e008228609ffd6575f2b34e8_2526d239-40f6-4a8b-9270-67fc4c52a4c6.jpg?v=1788917801","url":"https:\/\/voomisupply.com\/products\/sgs-66408-screw-machine-drill-bit-7-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
