Built to DIN 338 standards from M2 high speed steel with a bright, uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute configuration. The straight-cylindrical shank measures 0.71 mm in diameter, and the overall length is 28.00 mm with a 9.00 mm flute length. Web-thinned geometry with a tapered web reduces thrust and improves chip evacuation on entry. Intended for use by machinists, HVAC fabricators, plumbers, and electricians requiring tight-tolerance small-diameter drilling.\u003c\/p\u003e\u003cp\u003eThis Series 205 drill bit is suited for general-purpose drilling applications in residential and light commercial environments where small-diameter, high-accuracy holes are required. It handles cast iron and steel workpieces effectively, making it a go-to choice for sheet metal penetrations, bracket fabrication, and component mounting tasks in mechanical and electrical trades. The 5xD flute-to-diameter ratio supports stable chip removal in through-hole drilling at this size class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for durability in ferrous materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish for general-purpose use without coating interference\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDIN 338 specification compliance ensures consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.012 mm for tight-fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit per DIN 338 for use in standard drill chucks and collet systems accepting a straight-cylindrical shank at this diameter class.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed by machinists and trade professionals using a hand drill, drill press, or CNC setup with a compatible chuck or collet. Secure workpieces firmly before drilling to prevent deflection at this small diameter. Use appropriate cutting fluid or lubricant when drilling steel to extend tool life. Inspect the bit for tip damage before each use, as small-diameter bits are susceptible to breakage under side load or misalignment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.028 inches (0.71 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 70\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 9.00 mm\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.71 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.012 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9002050007100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51741560373554,"sku":"9002050007100","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_aef46d7d-7a7e-4070-b719-213c33815df6.jpg?v=1788832185","url":"https:\/\/voomisupply.com\/products\/guhring-9002050007100-jobber-drill-bit-0-028-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
