It measures 25\/64 inch (0.3906 inch) in diameter with an overall length of 4.5 inches and a flute length of 2.375 inches. The 150-degree drill point angle and three-flute spiral configuration support efficient chip evacuation and accurate entry, particularly in harder workpiece materials. The bright, uncoated finish is suited for use in materials where a coating is unnecessary or undesirable. Licensed machinists, tool and die makers, and precision metalworking professionals are the typical end users.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for right-hand cutting operations on CNC machining centers, manual drill presses, and hand-held drilling equipment where a straight cylindrical shank and ANSI-specification geometry are required. The regular spiral type and 5xD flute-to-diameter ratio make it a strong fit for through-hole and blind-hole drilling in ferrous and non-ferrous metals. It is sold as a single unit and conforms to ANSI specification standards, making it a direct fit for shops that source to print or tolerance callouts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003e150-degree drill point angle for reduced thrust and improved entry geometry\u003c\/li\u003e\n  \u003cli\u003eThree-flute spiral design promotes faster chip evacuation compared to two-flute configurations\u003c\/li\u003e\n  \u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for a broad range of metalworking applications\u003c\/li\u003e\n  \u003cli\u003eANSI specification geometry for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-specification jobber length drill bit compatible with standard straight-shank drill chucks and collet systems accepting a 25\/64 inch shank diameter across CNC and manual drilling equipment.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists or tooling professionals familiar with carbide cutting tool handling. Solid carbide bits are brittle and susceptible to chipping if subjected to side loads or improper clamping — secure the shank fully in a properly sized chuck or collet before operation. Ensure the spindle speed and feed rate are appropriate for the workpiece material and bit diameter before running. Inspect the cutting edges for chipping or damage before each use, as a compromised carbide edge can cause sudden tool breakage.\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\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.375 inches (2-3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\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\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: 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738843611442,"sku":"10421","price":183.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/116366f9348cb6d8e17e8f55234abea0.jpg?v=1788805424","url":"https:\/\/voomisupply.com\/products\/accupro-10421-solid-carbide-drill-bit-25-64-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
