Manufactured from high speed steel with an oxide coating, it offers improved lubricity and corrosion resistance compared to bright-finish HSS bits. The bit cuts at 12.00 mm (0.4724 inches) diameter with a standard 118-degree point angle and a right-hand spiral flute geometry. The straight-cylindrical shank seats in standard drill chucks without modification. Machinists, maintenance technicians, and fabricators use this bit for everyday hole-making operations across a wide range of workpiece materials.\u003c\/p\u003e\u003cp\u003eThis bit is suited for general-purpose production and maintenance drilling in job shop, manufacturing, and field environments. The 12.00 mm diameter falls within the 10.00 mm to 12.50 mm size range, and the 149.00 mm overall length provides the reach typical of jobber-series drills. The 111.00 mm flute length supports adequate chip evacuation in moderate-depth holes. This is a single-flute-geometry bit with two flutes, appropriate for handheld drill presses and CNC or manual machine tools running at standard HSS cutting speeds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12.00 mm (0.4724 inch) cutting diameter for precise hole sizing\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle  -  suited for general-purpose drilling across common materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for improved wear and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with two spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003cli\u003e111.00 mm flute length and 149.00 mm overall length  -  standard jobber proportions\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard 3-jaw and keyed drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill compatible with any standard drill chuck accepting a straight-cylindrical shank in the 12.00 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed and operated by machinists, toolroom technicians, and maintenance mechanics using drill presses, CNC machining centers, or handheld power drills. Secure the straight shank firmly in the chuck before operation and verify concentricity to minimize runout. Use appropriate cutting fluid or lubricant for the workpiece material to extend tool life. Replace the bit if cutting edges show chipping, excessive wear, or if the bit produces oversized holes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.00 mm (0.4724 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 149.00 mm (5.866 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 111.00 mm (4.370 inches)\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\/Finish\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.402.1200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51787614257458,"sku":"C.402.1200","price":22.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5e94acd9d0f892969b4765834aca113.jpg?v=1789217744","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1200-jobber-drill-bit-12-00-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
