It carries a No. 69 wire gauge size, equivalent to 0.0291 inches in diameter, and features a 120-degree standard point angle for accurate entry and reduced walking on hard materials. The spiral flute geometry promotes chip evacuation in small-diameter bores. With an overall length of 30 mm and a straight-cylindrical shank measuring 1.50 mm in diameter, this bit fits standard collet-style toolholders used in CNC machining, benchtop drill presses, and hand-held precision drilling equipment. It ships uncoated in a bright finish, leaving the carbide substrate exposed for high-speed performance in non-ferrous metals, plastics, and composites.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for machinists, tool-and-die technicians, and PCB fabricators who require consistent hole quality at sub-0.030-inch diameters. The miniature series designation indicates it is built for small-scale precision work, including instrument components, electronics housings, and fine mechanical assemblies. Its right-hand cutting direction is compatible with standard spindle rotation on conventional milling and drilling machines. The 5.60 mm flute length provides adequate chip clearance for shallow through-holes and blind holes typical in this size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 69 wire size at 0.0291 inches for precision small-diameter drilling\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e120-degree standard point angle reduces deflection on entry\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry with 5.60 mm flute length supports chip evacuation in shallow bores\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 1.50 mm diameter fits standard collet toolholders\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish, right-hand cut, regular spiral — no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style miniature series solid carbide drill bit compatible with collet-style toolholders and precision drill chucks accepting a 1.50 mm straight-cylindrical shank.

Secure the shank firmly in a properly sized collet or drill chuck before operation — carbide micro drills are brittle and will fracture if subjected to side loads or runout. Power down and de-energize the machine spindle completely before changing tooling. Follow the machine manufacturer's recommended spindle speeds for the workpiece material and this diameter to avoid premature breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 69\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0291 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\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\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\u003eFlute Length\u003c\/strong\u003e: 5.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30 mm\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: 1.50 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 1.75 inches (L) x 2.25 inches (W) x 0.25 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eItem Package Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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-6100074R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746387919154,"sku":"A-6100074R","price":200.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/31ce724d945eccfe924bca5b9b04d145.jpg?v=1788869345","url":"https:\/\/voomisupply.com\/products\/accupro-a-6100074r-no-69-micro-drill-bit-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
