The oxide coating reduces friction and helps resist heat buildup during drilling. At 168 mm overall length with a 122 mm flute length, this bit falls in the general-purpose jobber category suited for production and maintenance drilling in metal, wood, and plastic. Two right-hand spiral flutes evacuate chips efficiently, keeping the cut clean through the full depth of the hole. Licensed tradespeople and machine operators reach for this size when drilling anchor holes, clearance holes, and through-holes in structural stock.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for general-purpose drilling applications across a range of materials including mild steel, cast iron, aluminum, and thermoplastics. The straight cylindrical shank seats directly in standard drill chucks on drill presses, hand drills, and CNC machining centers without requiring a collet adapter. Its size range of 12.50 mm to 15.00 mm puts it in common use for mechanical, fabrication, and industrial maintenance work where a reliable, repeatable hole diameter is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13.50 mm (0.5315 inch) diameter for precise hole sizing in the mid-half-inch range\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry on a wide range of materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides toughness and wear resistance during extended use\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides moderate corrosion resistance\u003c\/li\u003e\n\u003cli\u003eTwo right-hand spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard three-jaw drill chucks without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill bit compatible with any standard drill chuck accepting a straight cylindrical shank in the 13.50 mm diameter range, including drill presses, hand drills, and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, and maintenance technicians using a standard keyed or keyless drill chuck. Secure the straight shank fully into the chuck before applying power and confirm the bit runs true before advancing into the workpiece. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and improve hole quality. Always wear eye protection and secure the workpiece before drilling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 13.50 mm (0.5315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 168 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 122 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\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: 0.15 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.402.1350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743277646130,"sku":"C.402.1350","price":40.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b174fc90defd14ebbf7cc46806c74e0.jpg?v=1788844957","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1350-jobber-drill-bit-13-50-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
