It is engineered for high-performance drilling in demanding materials where a standard HSS bit would wear prematurely. The Ti-NAMITE-X coating reduces friction and extends tool life in ferrous and non-ferrous applications alike. With a right-hand spiral flute and web-thinned point, the 56456 starts on center with minimal thrust and evacuates chips efficiently. Licensed machinists, tool-and-die professionals, and advanced fabricators are the primary users of this series.\u003c\/p\u003e\u003cp\u003eThe SGS 56456 fits vertical mills, CNC machining centers, and drill presses capable of running carbide tooling at appropriate surface footage. It is suited for production drilling in alloy steels, stainless steels, cast iron, and similar hard materials. The straight-cylindrical shank seats directly in standard drill chucks or collet holders. The Series 142P designation covers a 5xD flute-to-diameter ratio, making this bit appropriate for moderately deep hole applications within its rated maximum drilling depth of 23.00 mm (0.9055 inches). Coolant-through capability supports high-speed production runs where chip evacuation and heat management are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-X coating reduces friction and extends cutting edge life\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning for fast, on-center starts and reduced thrust\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed production drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with 5xD ratio for efficient chip evacuation at moderate depths\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 upgrade drill bit for use in standard drill chucks and collet systems accepting a 10.00 mm (0.5500 inch) straight-cylindrical shank; compatible with CNC machining centers, drill presses, and milling machines capable of running solid carbide tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling professionals familiar with carbide tooling requirements. Secure the straight-cylindrical shank firmly in a compatible chuck or precision collet before operation, and verify runout is within acceptable limits to prevent premature edge chipping. Always set spindle speed and feed rate appropriate for solid carbide tooling in the workpiece material. Enable coolant-through flow before starting the cut when using through-coolant capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 9.35 mm \/ 0.368 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Ti-NAMITE-X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: 61.00 mm \/ 2.4016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103.00 mm \/ 4.0551 inches\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: 10.00 mm \/ 0.5500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm \/ 1.5748 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 23.00 mm \/ 0.9055 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 1.94 mm \/ 0.0762 inches\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: +0.00028 to +0.00098 inches \/ +0.007 to +0.025 mm\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\u003ePackage Weight\u003c\/strong\u003e: 0.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 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: 56456\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51735695950130,"sku":"56456","price":374.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/76a9ab0cfcb51d58169c50e9cf15365d.jpg?v=1788773662","url":"https:\/\/voomisupply.com\/products\/sgs-56456-solid-carbide-jobber-drill-letter-u-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
