Manufactured from solid carbide, this bit delivers the rigidity and wear resistance required when drilling small-diameter holes in hard or abrasive materials. The 120-degree point angle provides accurate starting and reduces walking on entry. At 30 mm overall length with a 3.30 mm flute length, it is sized for shallow, high-precision bores common in instrumentation, electronics, and fine mechanical work. The bright, uncoated finish keeps the surface true to carbide geometry without coating buildup that could affect hole diameter at this scale.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is suited for use in CNC machining centers, drill presses, and precision hand-held spindles where consistent hole quality at 0.0248 inch diameter is required. Typical applications include circuit board drilling, watch and instrument component fabrication, medical device manufacturing, and fine metalwork. The straight-cylindrical shank fits standard collets and chucks sized for 1.50 mm shank diameter. Right-hand spiral flute geometry clears chips effectively in both ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard or abrasive materials\u003c\/li\u003e\n\u003cli\u003eWire gauge size 72 (0.0248 inch decimal) for tight-tolerance small-diameter drilling\u003c\/li\u003e\n\u003cli\u003e120-degree standard point angle for accurate entry and reduced walking\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish preserves true carbide geometry at micro-scale diameters\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 1.50 mm fits standard precision collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit micro drill bit for precision machining setups that accept a 1.50 mm straight-cylindrical shank in the ACCUPRO Miniature series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMicro drill bits at this diameter are typically installed and operated by machinists or precision fabricators using calibrated collet systems. Always confirm collet or chuck bore matches the 1.50 mm shank diameter before seating the bit. Secure the workpiece firmly to prevent movement during entry, as lateral deflection at this scale can cause immediate bit breakage. Use recommended RPM and feed rates for solid carbide micro bits in the material being drilled; do not force feed by hand.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 120 degrees\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\u003eOverall Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.30 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\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\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\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\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: A-6120063R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732220444978,"sku":"A-6120063R","price":195.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/57171b052632eaeaff1bb2175c679296.jpg?v=1788740555","url":"https:\/\/voomisupply.com\/products\/accupro-a-6120063r-micro-drill-bit-size-72-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
