Built from micrograin solid carbide with a TX coating, it delivers extended tool life and wear resistance compared to standard high-speed steel bits. The 135-degree split point reduces walking on entry and lowers thrust requirements. At 23\/64 inch (0.2795 inch decimal) in diameter with a 2.99-inch flute length and a 5-19\/32-inch overall length, this bit fits applications where a longer reach is needed beyond what a jobber-length drill provides. Coolant-through capability supports chip evacuation and heat control during deep-hole operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for universal material applications including steel, cast iron, stainless, aluminum, and engineered alloys. The Series 142P taper length format is commonly used in CNC machining centers, drill presses, and manual mill setups where extended reach into a workpiece is required. The cylindrical shank seats in standard drill chucks or collet systems. With an 8xD flute-to-diameter ratio, it is built for holes up to approximately 2.99 inches deep. A web-thinned geometry reduces cutting force and improves hole-entry performance across material types.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTX coating for extended tool life and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e135-degree standard point with web thinning for fast, accurate hole entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e8xD flute-to-diameter ratio allows drilling up to 2.99 inches deep\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide taper length drill bit for universal material applications per Series 142P.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Verify chuck or collet runout is within acceptable limits before use, as excessive runout accelerates carbide wear and can cause bit breakage. When using the coolant-through feature, confirm coolant pressure and flow rate are appropriate for the machine and material before commencing the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 142P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 23\/64 inch (0.2795 inch \/ 7.10 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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\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\/Finish\u003c\/strong\u003e: TX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.99 inches (76.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-19\/32 inches (114.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.315 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (35.99 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length x Diameter Ratio\u003c\/strong\u003e: 8xD\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: Cylindrical (Non-Threaded)\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: 2.99 inches (76.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 \/ +0.00083 inch (+0.006 \/ +0.021 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\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\u003eGrade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.61 x 0.7 x 0.7 inches\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: 66647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51733854945586,"sku":"66647","price":497.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/947f6ed78cf4a92e725732e5335ce663_fd601419-15bd-4983-9428-b9c744b1da3f.jpg?v=1788759608","url":"https:\/\/voomisupply.com\/products\/sgs-66647-taper-length-drill-bit-23-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
