Built to DIN 6537 specification, this Series 142P bit features a 135-degree standard point angle with web thinning for reduced thrust and cleaner entry. The micrograin solid carbide construction is coated with Ti-NAMITE-X (TX coating) for extended tool life and heat resistance. At 11\/32 inches in diameter with a flute-to-diameter ratio of 8xD, it is suited for deep-hole drilling where standard-length bits fall short. Licensed tradespeople and machinists working in metal fabrication, HVAC equipment manufacturing, and mechanical contracting rely on this geometry for consistent hole quality.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66658 is intended for universal material applications including steel, stainless, cast iron, and non-ferrous metals. The spiral flute and right-hand cut geometry evacuate chips efficiently during through-hole and blind-hole operations. The straight cylindrical shank with a 10 mm diameter seats cleanly in standard drill chucks and collet holders. Coolant-through capability makes this bit well suited for CNC machining centers and production drilling setups where extended run times and tight diameter tolerances are required. The flute length of 95 mm (3.74 inches) supports a maximum drilling depth of 3.74 inches.\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-speed applications\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating reduces friction and extends cutting edge life across universal material types\u003c\/li\u003e\n  \u003cli\u003e135-degree standard point angle with web thinning reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole and high-feed operations\u003c\/li\u003e\n  \u003cli\u003e8xD flute-to-diameter ratio provides taper length reach beyond standard jobber geometry\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 specification ensures dimensional consistency and interchangeability with DIN-compliant tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers, drill presses, and manual machines accepting a straight cylindrical shank with a 10 mm shank diameter. Suitable for use in standard drill chucks and precision collet holders compatible with straight-shank tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tool setter familiar with carbide tooling requirements. Ensure the machine spindle and chuck or collet are clean and free of runout before seating the shank. Carbide is brittle compared to high-speed steel — avoid lateral loading, interrupted cuts without proper feed rates, or drop impacts that can cause chipping. When using the coolant-through feature, confirm coolant pressure and flow rate are appropriate for the machine and material before beginning the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X (TX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 11\/32 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\u003ePoint Type\u003c\/strong\u003e: Standard with Web Thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 95 mm (3.74 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-19\/32 inches (141.99 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm (1.57 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.74 inches (95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 0.18 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.71 x 0.7 x 0.7 inches\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: 66658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51738021069106,"sku":"66658","price":546.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5449ef1d26031c989381aba60492b15.jpg?v=1788795687","url":"https:\/\/voomisupply.com\/products\/sgs-66658-taper-length-drill-bit-11-32-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
