Built from micrograin solid carbide and coated with AlTiN (Ti-NAMITE-A) finish, this bit delivers the heat resistance and edge retention needed when cutting hard, abrasive workpiece materials. It features a 145-degree split point with web thinning for self-centering entry, reducing the need for a center punch and minimizing walking on difficult surfaces. The 25\/64 inch (0.3906 inch) diameter and 4 inch overall length place it in the standard jobber range, making it a practical choice for machinists, tool-and-die technicians, and maintenance professionals working with exotic metals.\u003c\/p\u003e\n\u003cp\u003eThe SGS 51527 is suited for production and maintenance drilling in ferrous and non-ferrous hard alloys, including titanium and temperature-resistant alloys. The 5xD flute-to-diameter ratio and 2-13\/32 inch flute length support chip evacuation in moderate-depth holes up to 2-1\/8 inch maximum drilling depth. The straight cylindrical shank at 1\/2 inch diameter seats in standard drill chucks and collet holders. This bit is a Series 135L tool, optimized for applications where tool life and dimensional accuracy are priorities. No coolant-through capability; use external coolant when drilling at elevated speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior hardness and wear resistance in difficult alloys\u003c\/li\u003e\n  \u003cli\u003eAlTiN (Ti-NAMITE-A) coating provides high-temperature oxidation resistance when cutting titanium and heat-resistant alloys\u003c\/li\u003e\n  \u003cli\u003e145-degree split point with web thinning enables self-centering entry and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with regular spiral flutes promotes consistent chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical 1\/2 inch shank fits standard drill chucks and ER collet systems\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.00024 to +0.00083 inch supports close-tolerance hole applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and handheld drilling equipment with a 1\/2 inch or larger chuck or collet.

Ensure the spindle and chuck or collet are clean and within runout tolerances before seating the shank, as carbide bits are more brittle than high-speed steel and sensitive to eccentric loading. Do not use this bit without external coolant or lubrication when drilling titanium or hard alloys at elevated feed rates, as heat buildup accelerates edge wear. Inspect the cutting edge before each use; carbide chipping is not repairable and a damaged bit should be replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 25\/64 inch (0.3906 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (mm)\u003c\/strong\u003e: 9.92 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 145 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-13\/32 inches (2.4063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2-1\/8 inches (2.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1-9\/16 inches (1.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Micrograin 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\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\u003ePoint Type\u003c\/strong\u003e: Standard Self-Centering\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Temperature-Resistant Alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.00024 to +0.00083 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 135L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 51527\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA SGS PRECISION TOOLS","offers":[{"title":"Default Title","offer_id":51728381575474,"sku":"51527","price":370.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2bcee5d79879001dfba7a5f82bf371df.jpg?v=1788690793","url":"https:\/\/voomisupply.com\/products\/sgs-51527-jobber-drill-bit-25-64-solid-carbide-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
