Sized at wire gauge 81 with a decimal diameter of 0.0130 inches, this bit features a 130-degree point angle for accurate entry and reduced thrust. The spiral flute design promotes chip evacuation in confined bores. An AlTiN (aluminum titanium nitride) coating adds heat and wear resistance, extending tool life in abrasive or hard materials. The right-hand cut geometry is standard for conventional CNC and manual spindle use. At 1.5000 inches overall length with a 0.2300-inch flute length and a 1\/8-inch shank, it seats in standard collets and drill chucks without adapters.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for precision machining operations in aerospace, medical device, electronics, and general metalworking applications. It is appropriate for use in CNC machining centers, drill presses, and high-speed spindles where small-diameter hole accuracy is critical. The 1\/8-inch shank diameter makes it compatible with a wide range of standard toolholders. Machinists and tool-and-die professionals working with hardened steels, stainless, and high-temperature alloys will find the AlTiN coating particularly useful for maintaining edge integrity at elevated cutting speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge 81 size with 0.0130-inch decimal diameter for micro-scale drilling\u003c\/li\u003e\n  \u003cli\u003e130-degree split-style point angle reduces walking and entry burr\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides thermal and abrasion resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry aids chip evacuation in deep or blind holes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut for use with standard CNC and manual spindle rotation\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits common collets and chucks without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/8-inch collets, chucks, and toolholders on CNC machining centers, drill presses, and high-speed micro-drilling spindles requiring wire-gauge 81 drill capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by qualified machinists familiar with small-diameter tooling. Secure the 1\/8-inch shank fully in the collet or chuck to minimize runout before engaging the workpiece. Power down and de-energize the machine spindle completely before changing or inspecting tooling. Due to the small diameter, avoid side-loading and excessive feed rates that can cause breakage.\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: 81\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal)\u003c\/strong\u003e: 0.0130 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.2300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\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: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20130-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51753145467186,"sku":"20130-C3","price":45.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/359e640565fe94dcfe38c070c34c85c9_9a0229bf-3c11-4530-970f-9925c6d83863.jpg?v=1788933245","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20130-c3-micro-drill-bit-81-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
