Built to high-performance standards, it features a 130-degree point angle and a Diamond-Like Carbon (DLC) finish that reduces friction and extends tool life in non-ferrous applications. The bit measures 0.2031 inches (13\/64 inches) in diameter with an overall length of 2.955 inches. A regular spiral flute geometry and right-hand cut make it well-suited for CNC and manual drilling operations where consistent hole quality and chip evacuation are critical. Licensed machinists, tool-and-die professionals, and precision fab shops are the typical end users.\u003c\/p\u003e\u003cp\u003eThis drill bit is optimized for use in aluminum and composite materials, as indicated by the DLC coating and 130-degree point geometry, which is well matched to softer, gummy, or abrasive non-ferrous workpieces. The 6xD flute-to-diameter ratio supports deeper hole entry relative to diameter without sacrificing rigidity. With a straight cylindrical shank diameter of 0.2364 inches (6.00 mm), it fits standard collet chucks and drill chucks used in machining centers, drill presses, and CNC mills where tight tolerances and repeat accuracy are expected.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-performance drilling\u003c\/li\u003e\n\u003cli\u003eDLC (Diamond-Like Carbon) coating reduces friction and built-up edge in aluminum and composite materials\u003c\/li\u003e\n\u003cli\u003e130-degree point angle optimized for non-ferrous workpiece entry and centering\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank at 0.2364 inches (6.00 mm) for standard collet or chuck compatibility\u003c\/li\u003e\n\u003cli\u003eh6 diameter tolerance on the drill body for precise, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling aluminum and composite materials; belongs to the Harvey Tool Miniature High Performance Drills series and is intended for use in CNC machining centers, drill presses, and similar equipment accepting a straight cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician familiar with carbide tooling. Carbide drill bits are brittle compared to high-speed steel — avoid side loading, interrupted cuts, or excessive runout, which can cause chipping or fracture. Secure the shank fully in a collet or chuck to the manufacturer-recommended engagement depth before operation. Inspect the cutting edges and coating condition before each use and replace the bit at the first sign of wear to maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2031 inches (13\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Measured)\u003c\/strong\u003e: 0.2033 inches\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: DLC (Diamond-Like Carbon)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.3396 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.3396 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 6xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.955 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2364 inches (6.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Composite\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Miniature High Performance Drills\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: HARVEY TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DDA2031-C4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51727083536690,"sku":"DDA2031-C4","price":133.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/943ca55063ad05a3d136aa827b5e0e03.jpg?v=1788673021","url":"https:\/\/voomisupply.com\/products\/harvey-tool-dda2031-c4-jobber-drill-bit-13-64-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
