It features a standard 118-degree point angle and a bright, uncoated finish suited for dry or lightly lubricated drilling operations. The spiral flute geometry promotes chip evacuation from the cutting zone. With an overall length of 19.00 mm and a flute length of 2.50 mm, this bit is built for tight-tolerance work in small-diameter applications. The straight-cylindrical shank seats securely in standard drill chucks. This bit is installed by machinists, tool-and-die tradespeople, and precision fabricators.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for general-purpose drilling tasks where a small-diameter, right-hand cutting tool is required. The 0.27 mm diameter, equivalent to approximately 0.0106 decimal inches, makes it appropriate for applications such as pilot holes, watch-repair fixtures, circuit board prototyping, and fine metalwork. It is suitable for use in bench-top drill presses, precision hand drills, and CNC drilling operations where collet or chuck capacity accommodates the straight-cylindrical shank at this diameter range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for general-purpose durability across common workpiece materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for self-centering entry on flat and curved surfaces\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish with no additional coating that could alter the cutting edge geometry at this scale\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral design promotes chip clearing during drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard drill press and hand-drill rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets accepting sub-millimeter tooling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with any drill press, hand drill, or CNC spindle equipped with a chuck or collet system capable of holding a straight-cylindrical shank at the 0.27 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of small-diameter drill bits at this scale should be performed by machinists or fabricators familiar with micro-drilling techniques. Secure the workpiece firmly before drilling to prevent bit deflection or breakage. Use the lowest feed pressure necessary and apply cutting fluid when the material requires it. At sub-millimeter diameters, excessive side load or off-axis force will snap the bit; a drill press or guided fixture is strongly recommended over freehand operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.27 mm (0.0106 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 19.00 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\u003eDrill Point 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\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\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\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.401.0027\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727154872626,"sku":"C.401.0027","price":80.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2de5d2a204d1037725be3a1eb31a9288.jpg?v=1788674103","url":"https:\/\/voomisupply.com\/products\/hertel-c-401-0027-jobber-drill-bit-0-27-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
