Designed for precision small-hole drilling, this bit features a 120-degree standard point angle and a spiral flute with a regular spiral type for efficient chip evacuation. The straight-cylindrical shank measures 1.50 mm in diameter, making it compatible with standard precision collet chucks and drill presses used in fine-tolerance work. At 30 mm overall length with a 5.60 mm flute length, this bit is built for shallow, accurate holes in tight workspaces. The bright, uncoated finish suits use in non-ferrous metals, plastics, and PCB materials where coating buildup is a concern.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for machinists, electronics technicians, toolmakers, and precision fabricators working on small-diameter hole applications. Typical use cases include printed circuit board drilling, instrument components, watch parts, medical device fabrication, and other miniature machining operations requiring tight positional and diameter tolerances. The right-hand cutting direction is standard for conventional CNC machines and manual drill presses. This bit belongs to the Miniature series and is sold individually, with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 70 (0.0280 inches) for precision small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point angle for accurate hole entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with regular spiral type promotes chip clearance in shallow-depth applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for non-ferrous metals, plastics, and circuit board materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard precision collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard-fit micro drill bit for use in precision collet chucks, CNC machining centers, and benchtop drill presses that accept straight-cylindrical shanks with a 1.50 mm shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMicro drill bits of this size should be installed by a machinist or precision technician familiar with collet torque limits and runout specifications. Ensure the spindle and collet are clean and free of debris before seating the shank to prevent runout-induced breakage. At 0.0280 inches in diameter, this bit is highly susceptible to breakage from side loading, feed rate errors, or improper chuck seating. Coolant-through is not supported on this bit, so use an appropriate cutting fluid applied externally when drilling metals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\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\u003eSeries\u003c\/strong\u003e: Miniature\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A-6100071R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732089667890,"sku":"A-6100071R","price":200.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5a94ff7f711f27172e1f66662bee73a.jpg?v=1788739082","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100071r-micro-drill-bit-size-70-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
