It features a 135-degree split point for self-centering entry and reduced thrust, a Ti-NAMITE-X coating for extended tool life and heat resistance, and a web-thinned geometry that improves chip evacuation. The overall length is 3.58 inches (91.00 mm) with a 2.09-inch (53.00 mm) spiral flute length. This bit is suited for machinists, tool-and-die shops, and maintenance professionals working with hardened steels, stainless, cast iron, and other difficult-to-machine materials.\u003c\/p\u003e\n\u003cp\u003eThe SGS 56446 is built for precision drilling applications in metalworking environments where carbide rigidity and coating performance are required. It fits standard CNC machining centers, drill presses, and handheld drilling equipment with appropriate collets or chucks. The straight-cylindrical shank (0.39 inches \/ 8.00 mm diameter) mates with standard toolholders. With a maximum drilling depth of 0.91 inches (23.00 mm) and a 5xD flute-to-diameter ratio, this bit is appropriate for through-holes and shallow blind holes in production and job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eTi-NAMITE-X coating reduces friction and extends tool life in high-heat cutting conditions\u003c\/li\u003e\n  \u003cli\u003e135-degree point angle with web-thinned geometry for self-centering and reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports high-speed production drilling and chip flushing\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with straight-cylindrical shank for compatibility with standard toolholding\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 6537 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a high-performance OEM-style jobber drill in Series 142P, compatible with standard straight-shank toolholders and collet chucks accepting a 0.39-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tool-crib personnel familiar with carbide tooling. Secure the shank fully in the toolholder or collet and verify runout before operation, as carbide is brittle and sensitive to side-loading. When using the coolant-through feature, confirm coolant supply pressure and flow rate are appropriate for the application before starting the spindle. Inspect the cutting edge before each use and remove from service at the first sign of chipping or edge wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 6.35 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\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: 3.58 inches (91.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.09 inches (53.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.39 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.42 inches (36.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.91 inches (23.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.052 inches (1.32 mm)\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\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\u003eWeb Treatment\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inches (+0.006 to +0.021 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: 56446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51731232948530,"sku":"56446","price":310.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4618b64f9f3bfbc04c878027c7ec4851.jpg?v=1788728631","url":"https:\/\/voomisupply.com\/products\/sgs-56446-solid-carbide-jobber-drill-bit-letter-e","provider":"Voomi Supply","version":"1.0","type":"link"}
