It carries a 4.95 mm (0.1949 inch) diameter with a standard 118-degree split point and a web-thinned, tapered web geometry that reduces thrust and improves chip evacuation at entry. The straight-cylindrical shank seats directly in standard drill chucks without adapters. Overall length is 86 mm (3.39 inches), with a 52 mm (2.05 inch) flute length. Right-hand spiral flutes with a regular helix move chips away from the cutting zone efficiently during through-hole drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill is suited for general-purpose metalworking in job shop, maintenance, and light manufacturing environments. The 4.95 mm diameter falls in the 4.00 mm to 5.00 mm size range and is a common choice when drilling clearance holes, pilot holes, or through holes in mild steel, cast iron, aluminum, and similar materials. Machinists, toolroom technicians, and maintenance mechanics reach for this size when a close decimal-inch equivalent of 0.1949 inch is required. It conforms to DIN 338 geometry standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for hardness and heat resistance during dry or light-lubricated drilling\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces friction and provides mild corrosion resistance during storage and use\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle for general-purpose work on a wide range of metals\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces cutting thrust and improves centering on entry\u003c\/li\u003e\n\u003cli\u003eRight-hand regular spiral flute geometry for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003eDIN 338 specification with diameter tolerance of plus 0.000 to minus 0.018 mm\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber drill conforming to DIN 338, compatible with any standard drill chuck or driver accepting a 4.95 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis drill bit is installed and operated by qualified machinists or maintenance technicians using a drill press, milling machine, or hand drill with an appropriate chuck. Secure the shank fully in the chuck and verify runout before beginning a cut. Always apply cutting fluid or lubricant appropriate to the workpiece material to extend tool life and maintain dimensional accuracy. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.95 mm (0.1949 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: M2 High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 86 mm (3.39 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 52 mm (2.05 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4.95 mm (0.1949 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.000 to minus 0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 338\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: 0.02 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: 9002050049500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51739864793394,"sku":"9002050049500","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_57dfe9ac-2a34-4852-82db-18c17b8aa504.jpg?v=1788819801","url":"https:\/\/voomisupply.com\/products\/guhring-9002050049500-jobber-drill-4-95-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
