It measures 0.0571 inches in diameter with a 130-degree split point that reduces walking and allows clean entry without a center punch in many applications. The AlTiN coating increases surface hardness and heat resistance, extending tool life when drilling abrasive or hardened materials. At 1.5 inches overall length with a 1\/8-inch shank, this bit is sized for use in CNC machining centers, drill presses, and precision hand pieces. Machinists and tool and die professionals are the primary users of this style of miniature drill.\u003c\/p\u003e\n\u003cp\u003eThis micro drill is suited for high-precision work in metalworking, mold and die, electronics manufacturing, and aerospace component fabrication. The spiral flute geometry promotes chip evacuation in deep or blind holes, which is critical at this diameter to avoid breakage. The 1\/8-inch shank diameter makes it compatible with standard collet systems and miniature chuck setups commonly found in CNC and manual precision drilling equipment. Right-hand cut direction is standard for conventional CNC and drill press spindle rotation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.0571-inch drill diameter for micro and miniature hole applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance at small diameters\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating improves heat resistance and extends tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle reduces entry thrust and minimizes walk-off\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes chip clearance and reduces breakage risk\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, compatible with standard CNC and drill press spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/8-inch collet systems and miniature chucks in CNC machining centers, drill presses, and precision hand pieces that accept a 1\/8-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool should be installed by a qualified machinist familiar with miniature tooling setups. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the 1\/8-inch shank firmly in a clean, undamaged collet or chuck to minimize runout, which is especially critical at this diameter. Avoid applying excessive feed pressure, as solid carbide micro drills are brittle and susceptible to breakage if deflected or side-loaded.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Diameter\u003c\/strong\u003e: 0.0571 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.413 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\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\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\u003eSeries\u003c\/strong\u003e: Miniature Drills\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: HARVEY TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20355-C3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51738783088946,"sku":"20355-C3","price":42.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17850c947fc75af9534ccf940652f7f9_39f15b38-88ce-4c03-85fc-36a70e6329aa.jpg?v=1788804382","url":"https:\/\/voomisupply.com\/products\/harvey-tool-20355-c3-micro-drill-bit-0-0571-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
