Built to DIN 6537 specification, it carries a Ti-NAMITE-X coating that extends tool life and reduces heat buildup at the cutting edge. The 135-degree split point minimizes walking and reduces thrust force at entry. With a 6.70 mm diameter and 3.58-inch overall length, this drill is sized for precision hole-making in close-tolerance machining environments. It is installed and operated by machinists and toolroom technicians running CNC machining centers, drill presses, and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThe 66540 is designed for production and maintenance machining applications where tool longevity and dimensional accuracy are priorities. Its web-thinned geometry and spiral flute design promote chip evacuation in deeper cuts. Coolant-through capability supports elevated feed rates and extended run times in materials that generate significant heat. The straight-cylindrical shank seats directly into standard drill chucks or collet holders without adapters, making it compatible with a wide range of spindle configurations found in general metalworking shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating reduces friction and extends tool life versus uncoated carbide\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and prevents drill walking on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing and heat control at elevated feeds\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned construction improves cutting efficiency at the chisel edge\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 compliant geometry for consistent dimensional results across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber drill for use in standard drill chucks and collet holders accepting a 8.00 mm straight-cylindrical shank, consistent with Series 142P tooling configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis drill bit is installed by machinists and toolroom technicians. Secure the straight-cylindrical shank firmly in a calibrated chuck or collet holder before operation and verify runout with a dial indicator when tolerance is critical. Engage coolant-through supply before beginning the cut to protect the cutting edge and promote chip evacuation. Do not exceed the maximum drilling depth of 23.00 mm in a single pass without retracting to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.70 mm (0.2638 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm (3.58 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm (2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.2300 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.00 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 23.00 mm (0.91 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.39 mm (0.0546 inches)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute to Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00016 to +0.00063 inches (+0.004 to +0.016 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\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 66540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728511238450,"sku":"66540","price":257.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d6cb0f4e43dad5d6fed3fed9d2fd5e0.jpg?v=1788692443","url":"https:\/\/voomisupply.com\/products\/sgs-66540-solid-carbide-jobber-drill-6-70mm-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
