It measures 15\/64 inch (0.2300 inch) in diameter with a 150-degree drill point angle and a 3.25-inch overall length. The ALTiN (aluminum titanium nitride) coating extends tool life by reducing heat buildup and improving wear resistance at elevated cutting speeds. Three spiral flutes with a regular spiral type provide efficient chip evacuation, and the straight cylindrical shank ensures secure chuck retention. This bit is typically installed or used by machinists, tool-and-die tradespeople, and industrial maintenance technicians.\u003c\/p\u003e\u003cp\u003eThe ACCUPRO 50377 is suited for drilling ferrous and non-ferrous metals, hardened steels, cast iron, and other abrasive workpiece materials where standard high-speed steel bits fall short. The 1.375-inch flute length supports drilling to moderate depths in a single pass. Its 5xD flute-to-diameter ratio makes it a practical choice for production drilling, toolroom work, and precision maintenance applications. The right-hand cutting direction is standard for conventional drill press and CNC spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for superior hardness and wear resistance compared to HSS\u003c\/li\u003e\n\u003cli\u003eALTiN coating reduces friction and extends service life in high-temperature cutting conditions\u003c\/li\u003e\n\u003cli\u003e150-degree drill point angle minimizes walking and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eThree-flute design promotes efficient chip evacuation and improved feed rates\u003c\/li\u003e\n\u003cli\u003eRegular spiral type and 5xD flute ratio balance chip flow and rigidity\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit for use in standard drill chucks, collet systems, and CNC tool holders accepting a straight cylindrical shank in the 0.2000 to 0.2500 inch diameter range, per ANSI specification designation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety. Ensure the spindle is fully stopped and the machine is powered down before loading or removing the bit from the chuck or collet. Verify chuck or collet runout is within acceptable tolerance before operation, as excessive runout accelerates carbide edge wear and increases breakage risk. Do not use this bit for hand-drill applications; carbide tooling requires rigid machine setups to prevent chipping or fracture.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 15\/64 inch (0.2300 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: ALTiN\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: 1.375 inches (1-3\/8 inch)\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 50377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736164368690,"sku":"50377","price":119.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67159648624bcd06b53fde34df5ff6c3_40363458-588c-4c93-812a-3f5075258ab8.jpg?v=1788776276","url":"https:\/\/voomisupply.com\/products\/accupro-50377-carbide-drill-bit-15-64-inch-altin-150-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
