Built from solid carbide and coated with SGS Ti-NAMITE-A AlTiN finish, this bit handles alloy steels and titanium where high-speed steel tooling falls short. The 145-degree notched point reduces thrust and self-centers without a pilot hole. At 4.25 inches overall length with a 2.3125-inch flute length, it fits standard screw machine and CNC drill press setups. Machinists, tool-and-die techs, and production shop operators install this bit when workpiece material hardness or heat generation demands carbide construction.\u003c\/p\u003e\u003cp\u003eThis bit is suited for production drilling in alloy steels and titanium in both manual and CNC machine tool environments. The screw machine length format keeps the tool short and rigid, minimizing deflection in close-tolerance bores. The straight shank accepts standard 1\/2-inch drill chucks and collets without adapters. The 3xD flute-to-diameter ratio supports chip evacuation in blind and through-hole applications where swarf management is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high-heat and hard-material drilling in alloy steels and titanium\u003c\/li\u003e\n\u003cli\u003eTi-NAMITE-A AlTiN coating improves heat resistance and extends tool life at elevated cutting speeds\u003c\/li\u003e\n\u003cli\u003e145-degree notched point reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web configuration lowers cutting forces at the chisel edge\u003c\/li\u003e\n\u003cli\u003eScrew machine length OAL for maximum rigidity and reduced deflection in machine tool setups\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute geometry for consistent chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 1\/2-inch straight-shank screw machine length drill bits in standard drill chucks and collet systems; part of the SGS Series 135 product line with a diameter tolerance of +0.0003 to +0.0010 inches.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and locked out before loading or changing the bit. Use a properly sized chuck or collet matched to the 0.5-inch straight shank; do not overtighten beyond the chuck manufacturer's rated torque range. Verify workpiece fixturing and cutting parameters are appropriate for solid carbide tooling before starting the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-49\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN (Ti-NAMITE-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Alloy Steel, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0003 to +0.0010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 51363\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51730829902130,"sku":"51363","price":499.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f76b44f7e34536204d68c01d9f26669_b725277b-28e2-4310-97a5-78bc9060ca7c.jpg?v=1788723526","url":"https:\/\/voomisupply.com\/products\/sgs-51363-1-2-inch-solid-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
