It features a 1\/4 inch (0.2500 inch) diameter, a 150-degree drill point angle for reduced thrust and accurate entry, and a bright uncoated finish. The 3-flute spiral design improves chip evacuation and surface finish compared to standard 2-flute bits. At 3.25 inches overall length with a 1.5 inch flute length, this bit fits standard straight-shank drill chucks and is well suited for machinists, tool and die technicians, and fabricators working with carbide-appropriate substrates.\u003c\/p\u003e\u003cp\u003eThis bit is commonly used in machining, metalworking, and fabrication environments where hardened or abrasive materials require a more durable cutting tool than high-speed steel. Right-hand cutting direction and a regular spiral type make it compatible with conventional CNC machining centers, drill presses, and hand-held drill applications where a straight-cylindrical shank is accepted. The 5xD flute-to-diameter ratio supports efficient chip clearing in moderate-depth holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for durability in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e150-degree drill point angle reduces entry thrust and improves centering\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design enhances chip evacuation and finish quality\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a wide range of drilling applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eANSI specification designation ensures dimensional conformance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length straight-shank drill bit compatible with drill presses, CNC machining centers, and hand-held drills accepting a 1\/4 inch straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or trade professionals familiar with carbide tooling. Secure the shank fully in the chuck or collet before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Carbide bits are brittle and should not be used in applications with significant lateral load or vibration beyond their rated use. Inspect the cutting edges before each use and replace if chipping or wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 150 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.5 inches\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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 Designation\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 10381\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730737234226,"sku":"10381","price":106.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dacd717f09cf352d8380426e57e8dd8.jpg?v=1788721968","url":"https:\/\/voomisupply.com\/products\/accupro-10381-jobber-drill-bit-1-4-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
