At 0.30 mm in diameter (0.0118 inches decimal equivalent), this is a micro-diameter drill intended for precision work in soft to medium-hardness materials. The bright, uncoated finish is standard for HSS drills used in lower-speed, general-purpose operations. With an overall length of 19 mm and a spiral flute design, the bit provides adequate chip evacuation for its size class. It is sold individually but carries a minimum order quantity of 12 units.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for light-duty production drilling, toolroom work, electronics assembly, and instrument fabrication where extremely small-diameter holes are required. Right-hand cutting direction is standard for conventional drill press and CNC spindle use. The straight-cylindrical shank seats directly into standard collets or chucks capable of holding micro-diameter tooling. Applications typically include circuit board drilling, watch and instrument repair, and fine metalworking where hole location tolerance is tight.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.30 mm diameter with 0.0118 inch decimal equivalent for micro-precision drilling\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry geometry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction suitable for a wide range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for standard-speed general-purpose use\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes chip evacuation in small-diameter bores\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard micro collets and chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any drill press, CNC machining center, or hand tool equipped with a chuck or collet capable of holding a 0.30 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMicro-diameter drill bits require a rigid, well-centered setup to prevent breakage — runout at the spindle should be minimized before use. Secure the workpiece firmly and use the lowest practical feed pressure appropriate to the material. Ensure the chuck or collet is rated for the shank diameter to maintain concentricity. Handle micro drills carefully; they are fragile at this diameter and should not be used in worn or high-runout spindles.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.30 mm (0.0118 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C.401.0030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727520432434,"sku":"C.401.0030","price":80.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d875cf891d549ab9430ee0a79a687ed4.jpg?v=1788678833","url":"https:\/\/voomisupply.com\/products\/hertel-c-401-0030-jobber-drill-bit-0-30-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
