It measures 12.20 mm (0.4803 inches) in diameter with a 149 mm overall length and a 111 mm flute length. The 118-degree standard point geometry delivers reliable starting and consistent hole quality across a wide range of workpiece materials. The high speed steel construction with an oxide coating provides basic lubricity and surface protection during cutting. This drill bit is suited for use in drill presses, CNC machining centers, and handheld power drills used in fabrication and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis jobber drill is intended for general-purpose drilling applications across manufacturing, fabrication, maintenance, and repair operations. The straight-cylindrical shank seats securely in standard three-jaw chucks and keyless chucks without special collets or adapters. With a right-hand spiral flute configuration and two-flute design, the bit clears chips efficiently through the flute channel during through-hole and blind-hole drilling. It falls within the 10.00 mm to 12.50 mm drill bit size range and is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12.20 mm diameter with 118-degree standard point angle for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with oxide coating for surface protection and basic lubricity\u003c\/li\u003e\n\u003cli\u003eTwo right-hand spiral flutes promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e149 mm overall length with 111 mm flute length for jobber-length reach\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard three-jaw and keyless chucks\u003c\/li\u003e\n\u003cli\u003eGeneral-purpose grade suitable for drill presses, CNC equipment, and handheld drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit compatible with any machine or handheld drill equipped with a standard three-jaw or keyless chuck sized to accept a straight-cylindrical shank in the 10.00 mm to 12.50 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only with the machine powered off and the spindle fully stopped. Secure the straight-cylindrical shank firmly in the chuck before operation to prevent slippage or runout. Wear appropriate eye protection per shop safety standards when operating any rotary cutting tool. Inspect the cutting edges for wear or damage before each use and replace bits that show chipping or dullness to maintain hole quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 12.20 mm (0.4803 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 149 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 111 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\u003ePoint Type\u003c\/strong\u003e: Standard\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\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\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.402.1220\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51743337873714,"sku":"C.402.1220","price":28.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac36416c409c779dca677de7b0641d9a.jpg?v=1788845834","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-1220-jobber-drill-bit-12-20-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
