Built from micrograin solid carbide and coated with Ti-NAMITE-X, it delivers extended tool life and heat resistance in demanding production environments. The 135-degree split point and web-thinned geometry reduce thrust force and improve centering at entry. With an overall length of 2.5984 inches and a 5.20 mm diameter, this bit fits standard CNC machining centers, drill presses, and screw machine setups. Installation and operation are handled by machinists and tooling technicians in shop environments.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production drilling in metals, composites, and universal workpiece materials where tool consistency and tight diameter tolerances matter. The straight-cylindrical shank measures 6 mm in diameter and 1.4173 inches in length, making it compatible with standard collet and chuck systems. Coolant-through capability supports high-speed drilling cycles by delivering cutting fluid directly to the cutting zone, reducing heat buildup and chip evacuation issues. The Series 142P design conforms to DIN 6537 specification, a common standard in precision machining and toolroom environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point with web thinning for reduced entry thrust and accurate hole positioning\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for chip control and thermal management\u003c\/li\u003e\n  \u003cli\u003e4-margin geometry provides enhanced bore straightness and surface finish\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.00016 to plus 0.00063 inches ensures consistent hole sizing across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537-compliant screw machine length drill bit for use in CNC machining centers, drill presses, and screw machine applications with standard collet or drill chuck systems accepting a 6 mm straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed and operated by machinists or tooling technicians in machine shop environments. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify collet or chuck bore size matches the 6 mm shank diameter before seating the bit. When using coolant-through capability, confirm the machine spindle and toolholder are equipped for through-coolant delivery before enabling coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.20 mm (0.2047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66 mm (2.5984 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 mm (1.1024 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.2300 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.4173 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\u003eDrill Point Length\u003c\/strong\u003e: 1.08 mm (0.0424 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.1024 inches\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, 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\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\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: plus 0.00016 to plus 0.00063 inches (plus 0.004 to plus 0.016 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 66422\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51735434330418,"sku":"66422","price":219.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eb64690496fe817af3dab98453b53ad5.jpg?v=1788772433","url":"https:\/\/voomisupply.com\/products\/sgs-66422-screw-machine-drill-bit-5-20mm-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
