Built from solid carbide with a Ti-NAMITE-A AlTiN (aluminum titanium nitride) coating, it delivers high heat and wear resistance in demanding cutting applications. The bit features a 145-degree notched point angle and web-thinned, tapered web construction for improved penetration and reduced thrust. With a 2-flute regular spiral configuration and a 0.1250-inch (1\/8 inch) diameter, this bit suits machinists and fabricators working in alloy steels and titanium where tool life and dimensional accuracy are critical.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in CNC machining centers, drill presses, and screw machine setups where a short, rigid cutting tool is needed to maintain tight tolerances. Its screw machine length — 2.5 inches overall — provides added stiffness compared to jobber-length bits, making it well-suited for high-speed production drilling in alloy and titanium workpieces. The straight shank and 0.2500-inch shank diameter allow standard collet or chuck mounting. It is typically installed and operated by machinists, tool-and-die professionals, and precision fabricators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with AlTiN (Ti-NAMITE-A) coating for extended tool life in hard materials\u003c\/li\u003e\n\u003cli\u003e145-degree notched point angle reduces walking and improves self-centering on entry\u003c\/li\u003e\n\u003cli\u003eWeb-thinned, tapered web lowers thrust requirements and aids chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length (2.5 inches OAL) provides rigidity for close-tolerance drilling\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design with 3xD flute-to-diameter ratio supports efficient chip flow\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight shank for standard collet or drill chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw machine length replacement or production drill for use in alloy steel and titanium workpieces.

Ensure the machine spindle is fully stopped and locked before changing tooling. Use cutting fluid or coolant appropriate for the workpiece material when drilling titanium or high-alloy steels, even though this bit does not feature through-coolant capability. Verify spindle speed and feed rate against carbide tooling recommendations before running production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 3.18 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4375 inches (1-7\/16 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Notched\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\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\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\u003eNumber of Margins\u003c\/strong\u003e: 2\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: 51330\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51735191945522,"sku":"51330","price":185.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c42d3a7f1c7dbbf52490c7391b3e01a.jpg?v=1788770168","url":"https:\/\/voomisupply.com\/products\/sgs-51330-screw-machine-drill-bit-1-8-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
