It features a 118-degree standard point angle and a spiral flute geometry that promotes chip evacuation and consistent hole entry. The oxide coating provides a modest layer of surface protection against corrosion and moderate heat. At 1.40 mm in diameter and 48 mm overall length, this bit is suited to precision drilling work where tight tolerances and small bore diameters are required. Machinists, toolroom technicians, and maintenance professionals are the primary users.\u003c\/p\u003e\u003cp\u003eThis bit is sized at 1.40 mm, equivalent to approximately 0.0551 decimal inches, placing it in the small-diameter range commonly used for pilot holes, circuit board work, instrument assemblies, and fine metalworking applications. Its straight-cylindrical shank fits standard drill chucks on bench drills, CNC drilling centers, and handheld power tools. The right-hand cutting direction is compatible with conventional forward-rotation spindles found on the vast majority of drilling equipment in trade and shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.40 mm diameter with 118-degree standard point for clean entry on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction offers durability across general-purpose drilling applications\u003c\/li\u003e\n\u003cli\u003eOxide coating provides corrosion resistance and mild heat protection\u003c\/li\u003e\n\u003cli\u003eSpiral flute design with two flutes promotes efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with conventional forward-rotation spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit suitable for use in standard drill chucks accepting straight-cylindrical shanks across bench drills, drill presses, and CNC drilling equipment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only with the spindle fully stopped and the machine power off or locked out per standard OSHA lockout\/tagout procedures. Secure the straight-cylindrical shank firmly in the chuck and verify concentricity before initiating a cut. Use appropriate cutting fluid or coolant for metal drilling to extend bit life, especially at high spindle speeds with small-diameter bits. Inspect the cutting edges for wear or chipping before each use, as small-diameter HSS bits are susceptible to breakage under side load or excessive feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.40 mm (0.0551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 48 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\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\u003c\/strong\u003e: Oxide\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: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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.402.0140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51741149954354,"sku":"C.402.0140","price":42.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fafb9237809e3955d54d4e0bba8aad45.jpg?v=1788829635","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-0140-jobber-drill-bit-1-40-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
