Built from M2 high speed steel with an oxide coating, it offers solid wear resistance in production and maintenance environments. The bit measures 4 mm in diameter with a 75 mm overall length and a 43 mm flute length, ground to a 118-degree standard point angle. A tapered web with web thinning reduces thrust force at the point and improves chip flow. Machinists, tool-and-die techs, and general metal fabricators are the primary users of this series.\u003c\/p\u003e\u003cp\u003eThis drill bit suits light to medium drilling operations in cast iron and steel workpieces. The 5xD flute-to-diameter ratio provides good chip evacuation in through-hole and blind-hole applications. The straight cylindrical shank fits standard drill chucks on benchtop drill presses, CNC machining centers, and handheld drill motors. No coolant-through capability is required for the typical applications this bit handles, making it straightforward to deploy in shop floor settings where coolant infrastructure is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high speed steel construction for hardness and heat resistance in metal cutting\u003c\/li\u003e\n\u003cli\u003eOxide coating reduces surface friction and provides corrosion protection\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute geometry promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 338 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in cast iron and steel workpieces, conforming to DIN 338 Series 205 standards and fitting any standard chuck sized for a 4 mm straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians. Secure the shank fully in a drill chuck and verify runout before drilling. Power down or de-energize the machine and engage any spindle lock before changing bits. Avoid excessive feed pressure, as this can cause bit deflection or premature edge wear, particularly in harder steel grades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 75 mm (2.953 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 43 mm (1.693 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 32 mm (1.260 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 37 mm (1.457 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\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\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 -0.018 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\u003eWeight\u003c\/strong\u003e: 0.2 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: 9002050040000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51742621237554,"sku":"9002050040000","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_5a4bf35c-6ddc-49d5-a6d9-4c81e8a9111c.jpg?v=1788838403","url":"https:\/\/voomisupply.com\/products\/guhring-9002050040000-4mm-hss-jobber-drill-bit-118","provider":"Voomi Supply","version":"1.0","type":"link"}
