Built from micrograin solid carbide and coated with Ti-NAMITE-X, this bit delivers extended tool life and edge retention in demanding production environments. It measures 3\/8 inches in diameter with a 3-1\/2 inches overall length and features a 135-degree split point for fast, self-centering starts with minimal walking. The two-flute spiral design with web thinning promotes efficient chip evacuation. Coolant-through capability makes it suitable for CNC and automated machining centers where through-spindle coolant is available. Machinists and tool-and-die professionals are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThe SGS 66448 is suited for universal workpiece materials, including steel, stainless, aluminum, cast iron, and similar alloys. The screw machine length format — shorter overall length relative to standard jobber bits — provides increased rigidity and reduced deflection, making it the preferred choice for high-tolerance hole work in machining cells, drill presses, and CNC machining centers. The straight-cylindrical shank fits standard drill chucks and collet systems without adaptation. Series 142P is engineered for high-performance production drilling where cycle times and hole quality are both critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for hardness and wear resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating reduces friction and extends tool life across a broad range of materials\u003c\/li\u003e\n  \u003cli\u003e135-degree split point with web thinning for self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with through-spindle coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3-1\/2 inches OAL) provides added rigidity over jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eFour-margin geometry improves hole roundness and surface finish\u003c\/li\u003e\n  \u003cli\u003eDIN 6537 specification compliance for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style production drill bit for use in standard drill chucks and collet holders accepting a 0.390 inch straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating depth and runout before beginning a production run. Consult your machine tool manufacturer guidelines and applicable shop safety standards when setting feed rates and spindle speeds for carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/8 inches (0.3071 decimal inch \/ 7.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches (3.1102 decimal inch \/ 79 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6142 inches (41.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.390 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4173 inches (36.00 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\u003eDrill Point Length\u003c\/strong\u003e: 0.0636 inches (1.62 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6142 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\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\u003ePoint Type\u003c\/strong\u003e: Standard, Web-Thinned\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 66448\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51739056537906,"sku":"66448","price":264.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4ba187ea281224c7c1cc20ca500d9d4c.jpg?v=1788808611","url":"https:\/\/voomisupply.com\/products\/sgs-66448-screw-machine-drill-bit-3-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
