It is ground from high speed steel (HSS) and finished with an oxide coating that provides light lubricity and corrosion resistance during cutting. The bit measures 1.20 mm in diameter (0.0472 inches) with a standard 118-degree split-free point, a 22 mm flute length, and a 48 mm overall length (approximately 1.89 inches). The straight-cylindrical shank seats directly in standard drill chucks and collets. Machinists, tool-and-die shops, and maintenance technicians install this bit for fine-diameter work where consistent geometry and repeatable entry are required.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for light-duty and precision drilling applications in shop and field environments. The 1.20 mm diameter places it in the micro-drill range, making it appropriate for circuit board pilot holes, small fastener clearance holes, and instrument or fixture work. The two-flute spiral design promotes chip evacuation in both hand-held and machine-mounted operations. It is a single-piece-per-package item sold in multiples of 12, consistent with typical shop stock and crib replenishment purchasing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.20 mm diameter with 0.0472-inch decimal equivalent for cross-reference with inch-based print callouts\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose entry in a wide range of materials\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides hardness and toughness for repetitive drilling cycles\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction at the cutting edge and offers light corrosion protection during storage\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry evacuates chips efficiently and is compatible with standard drill press and CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks, collets, and quick-change adapters without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in any standard drill press, CNC machining center, or hand drill equipped with a chuck capable of holding a straight shank in the 0.00 mm to 2.00 mm diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified technician should inspect the chuck or collet for runout before seating the bit, as micro-diameter drills are sensitive to concentricity errors. Power down the machine and release all stored energy before changing tooling. Use appropriate cutting fluid or mist when drilling ferrous metals to extend tool life and maintain hole quality. Do not exceed the spindle speed range recommended for the workpiece material and bit diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.20 mm (0.0472 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint 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\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\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\u003ePackage Quantity\u003c\/strong\u003e: 1 piece\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.402.0120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51744215302450,"sku":"C.402.0120","price":44.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed71ae15f0b27cb3cfdca13da5e44ea7.jpg?v=1788855089","url":"https:\/\/voomisupply.com\/products\/hertel-c-402-0120-jobber-drill-bit-1-20-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
