It features a 1.35 mm (0.0531 inch) diameter with a standard 118-degree point angle, an oxide coating for added surface hardness, and a right-hand spiral flute geometry. The straight-cylindrical shank seats securely in standard drill chucks. At 48 mm overall length with a 22 mm flute length, this bit is suited for shallow to mid-depth holes in light production and maintenance work. It is manufactured from high speed steel, making it a dependable choice for general shop, fabrication, and field drilling tasks.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for use in hand drills, drill presses, and CNC or manual lathes where a small-diameter, general-purpose bit is required. The 1.35 mm size is commonly used for pilot holes, small fastener clearance, and precision layout work in sheet metal, aluminum, mild steel, and similar materials. The oxide finish helps reduce friction during the cut. It is sold as a single unit and is appropriate for machinists, tool-and-die workers, HVAC fabricators, electricians, and maintenance technicians who need a reliable small-diameter drill in their kit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.35 mm (0.0531 inch) diameter for small-hole and pilot-hole applications\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose use across multiple materials\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute design with two flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks without adapters\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides durability in light to moderate cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit for use in standard drill chucks and collets accepting straight-cylindrical shanks in the 0.0500 to 0.1000 inch (0.00 to 2.00 mm) drill size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist or maintenance technician into a keyed or keyless drill chuck on a hand drill, drill press, or machine tool. Secure the shank fully in the chuck before operation and confirm the spindle is at a full stop before bit changes. Use appropriate cutting fluid when drilling steel to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace if chipping or dulling is observed, as small-diameter bits are susceptible to breakage under side load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.35 mm (0.0531 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 48 mm (approximately 1.89 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 22 mm (approximately 0.87 inches)\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.402.0135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739346731314,"sku":"C.402.0135","price":36.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cca0b83fe7c589f2f2e43a1c8e6f0f7b.jpg?v=1788813418","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-0135-jobber-drill-bit-1-35-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
