It carries a wire gauge size of 51, corresponding to a decimal diameter of 0.0670 inches, and features a 140-degree drill point angle optimized for flat-bottomed entry and reduced walking on hard surfaces. The AlTiN Nano coating adds heat resistance and surface hardness, extending tool life in demanding cutting conditions. With a right-hand cutting direction and spiral flute geometry, this bit is part of Harvey Tool's Miniature High Performance Drills series built specifically for hardened steel applications.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is intended for use on hardened steel workpieces in precision machining environments, including tool and die, mold making, aerospace component work, and medical device manufacturing. Its compact overall length of 50.00 mm and 3.00 mm shank diameter make it compatible with standard collet systems used on CNC machining centers and high-speed spindles. The h6 diameter tolerance on the drill body supports accurate, repeatable hole sizing in tight-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened steel\u003c\/li\u003e\n  \u003cli\u003eAlTiN Nano coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle reduces thrust and improves entry accuracy\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eh6 diameter tolerance for tight, consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003e3.00 mm shank diameter suits standard collet toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling hardened steel as both primary and secondary workpiece material.

Always verify spindle runout is within acceptable limits before running micro-diameter tooling, as excessive runout accelerates breakage. Power down the spindle completely before changing tooling. Follow machine manufacturer guidelines and applicable shop safety standards when handling carbide cutting tools.\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: 51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0670 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: AlTiN Nano\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.3150 inches (8.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Steel\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: CSG0670-C6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HARVEY TOOL","offers":[{"title":"Default Title","offer_id":51749696504114,"sku":"CSG0670-C6","price":85.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed1f1a912d82549b987beb42bb3dcfd5_9d165a59-da0b-4e99-8c16-ee1bbbf4059c.jpg?v=1788909320","url":"https:\/\/voomisupply.com\/products\/harvey-tool-csg0670-c6-micro-drill-bit-0-0670-in-wire-51","provider":"Voomi Supply","version":"1.0","type":"link"}
