Built to DIN 6537 specification, it features a 135-degree split point, web-thinned tip, and a Ti-NAMITE-X (TX) coating that extends tool life in demanding applications. The cylindrical shank measures 25\/64 inch in diameter, and the bit delivers an 8xD flute-length-to-diameter ratio, making it well suited for deeper hole depths relative to its size. Coolant-through capability supports chip evacuation and heat management during continuous cutting operations. Machinists, tool-and-die professionals, and maintenance technicians rely on this geometry for consistent, accurate hole placement.\u003c\/p\u003e\u003cp\u003eThe SGS 66649 is designed for universal material application, performing in steel, stainless, cast iron, aluminum, and similar workpiece materials. Its micrograin carbide substrate and spiral flute geometry make it a strong fit for CNC machining centers, drill presses, and manual mills where taper length reach is required. The right-hand cut, standard point style, and web-thinned tip reduce thrust force at entry and improve hole quality in both through-hole and blind-hole configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X (TX) coating reduces friction and extends cutting life\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning lowers entry thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation in deep-hole drilling\u003c\/li\u003e\n\u003cli\u003e8xD flute-length-to-diameter ratio provides extended reach capability\u003c\/li\u003e\n\u003cli\u003eDIN 6537 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style taper length drill bit for use in standard cylindrical-shank toolholders compatible with a 25\/64 inch straight shank.

Secure the cylindrical shank in a clean, properly sized collet or drill chuck to the toolholder manufacturer's specified clamping torque range. Verify coolant-through passages are clear and that system pressure is appropriate for the toolholder before initiating a cut. Inspect the cutting edges for chipping or wear before each use and replace the bit when dimensional tolerance or surface finish degrades.\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: 25\/64 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, Web-Thinned\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: Ti-NAMITE-X (TX)\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 8xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 76 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-19\/32 inches (114 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.51 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 6537\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: 66649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51755096965426,"sku":"66649","price":497.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1d6e4cefbf314d1571d070f02bc34a1.jpg?v=1788951068","url":"https:\/\/voomisupply.com\/products\/sgs-66649-taper-length-drill-bit-25-64-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
