Built from M2 high speed steel with a bright uncoated finish, it features a standard 118-degree split-point geometry and a regular spiral flute for efficient chip evacuation. The overall length is 30.00 mm with a 10.00 mm flute length. Manufactured to DIN 338 specification, this bit delivers consistent dimensional accuracy with a diameter tolerance of +0.000 to -0.012 mm. It is suited for general-purpose drilling in metalworking, maintenance, and light fabrication environments where a small-diameter HSS bit is required.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for small-diameter drilling operations across a wide range of base materials including mild steel, aluminum, brass, and similar machinable metals. It fits standard drill chucks and collets sized for a 0.84 mm shank diameter. Typical applications include pilot holes, reference holes, and precision through-holes in sheet metal or light structural stock. Machinists, tool-and-die workers, and maintenance technicians in production and field settings are the primary users of this bit size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size No. 66 with 0.0331 inch decimal equivalent for precise small-diameter drilling\u003c\/li\u003e\n\u003cli\u003eM2 high speed steel construction provides good wear resistance and heat tolerance\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle suits general-purpose drilling in common metals\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral flute promotes controlled chip removal in shallow holes\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets without modification\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 338 specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 338-specification jobber drill for use in standard drill chucks and collets accepting a 0.84 mm straight-cylindrical shank, suitable for bench drills, CNC drill heads, and handheld power tools in the applicable size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is intended for installation by machinists or qualified maintenance technicians familiar with small-diameter tooling. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Small-diameter bits are susceptible to breakage from side loading and excessive feed pressure — use appropriate feed rates for the material and bit diameter. Disengage the machine and allow all rotation to stop completely before changing or inspecting the bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 66\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0331 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 30.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.84 mm (0.0331 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular 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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eSpecification\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.002 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: 9002050008400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729182884146,"sku":"9002050008400","price":39.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83d69f89c46fbc452b6fc7bec513ac36_f2672b49-11dd-4ea6-9601-1637c22406b6.jpg?v=1788701551","url":"https:\/\/voomisupply.com\/products\/guhring-9002050008400-no-66-hss-jobber-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
