Built to DIN 338 standards, it features a 0.45 mm diameter, a standard 118-degree point angle, and a bright uncoated finish. The two-flute spiral design with a regular helix and web-thinned, tapered web configuration promotes efficient chip evacuation and reduced entry force. The straight-cylindrical shank provides consistent runout in standard drill chucks. This is a general-purpose tool suited for production and maintenance work where small-diameter accuracy is required.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized for fine-detail and small-bore work in cast iron and steel. At 0.45 mm in diameter and 20 mm overall length, it fits applications where standard jobber-length drills are needed at the sub-millimeter scale. Typical use cases include precision component manufacturing, electronics assembly fixtures, tool and die work, and general metalworking operations. The 5xD flute-to-diameter ratio supports drilling to a maximum depth of 4.33 mm without coolant-through capability.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.45 mm drill diameter with a tolerance of +0.000 to -0.010 mm for tight-tolerance bore work\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust force\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction for durability across cast iron and steel workpieces\u003c\/li\u003e\n\u003cli\u003eDIN 338 specification compliance ensures consistent dimensional standards\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for general-purpose metal drilling without coating degradation concerns\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral, two-flute design for predictable chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill for use in cast iron and steel workpieces, conforming to DIN 338 standards and fitting any standard drill chuck or collet accepting a 0.45 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by machinists, tool and die makers, or trained technicians using a drill press, CNC machining center, or precision hand drill. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation. At sub-millimeter diameters, excessive feed rate or lateral force will cause breakage; follow machine manufacturer feed and speed recommendations for M2 HSS at the workpiece material. Inspect the drill point for wear or chipping before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.45 mm (0.0177 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 20 mm (0.787 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5 mm (0.197 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 15 mm (0.591 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.45 mm (0.0177 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.33 mm (0.170 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, Regular\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.010 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 205\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.002 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002050004500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732578402610,"sku":"9002050004500","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_ec05f953-24f5-4a89-b307-fedf7f555127.jpg?v=1788744615","url":"https:\/\/voomisupply.com\/products\/guhring-9002050004500-jobber-drill-bit-0-45-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
