Built from solid carbide with a bright\/uncoated finish, it delivers consistent performance in demanding materials including steel, alloy steel, stainless steel, cast iron, nickel alloy, titanium, and aluminum silicate. The bit features a 135-degree split point for accurate self-centering and reduced walking on entry. With a right-hand cut, slow spiral flute design, and web-thinned tapered web configuration, it is engineered for general-purpose use across a wide range of shop and production environments. The straight-cylindrical shank ensures secure seating in standard drill chucks and collets.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in CNC machining centers, drill presses, and manual machines where screw machine length tooling is specified. The shorter overall length of 2.5 inches provides added rigidity compared to jobber-length bits, making it a preferred choice when drilling shallow holes in tough alloys or cast materials. It is commonly used by machinists, tool and die makers, and maintenance technicians working in industrial, manufacturing, and fabrication settings. The 5xD flute-to-diameter ratio supports adequate chip evacuation at typical feed and speed parameters for this bit size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for hardness and wear resistance in ferrous and non-ferrous metals\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces thrust and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web lowers cutting resistance and extends tool life\u003c\/li\u003e\n  \u003cli\u003eSlow spiral flute geometry optimized for harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for use with cutting fluids across a broad material range\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in materials including steel, alloy steel, stainless steel, cast iron, aluminum silicate, nickel alloy, titanium, and titanium alloy.

Secure the shank fully in the chuck or collet before operation to prevent runout or pullout. Coolant-through is not supported on this bit, so flood coolant or cutting oil applied externally is recommended when drilling stainless steel, nickel alloys, or titanium. Inspect the cutting edges before each use and do not run a chipped or cracked carbide bit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch, 6.35 mm)\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: 1.375 inches (34.90 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 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: Slow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Bright\/Uncoated\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.013 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.052 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 215-2500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742127784242,"sku":"215-2500","price":61.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dfe9197e1abe5661a0eac9a0374f7f16.jpg?v=1788835435","url":"https:\/\/voomisupply.com\/products\/osg-215-2500-screw-machine-drill-bit-0-25-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
