At 1.1 mm in diameter and 50 mm overall length, this bit delivers extended reach compared to standard jobber-length drills. The 118-degree point angle and web-thinned tip reduce entry force and improve chip evacuation. Right-hand spiral flutes with a regular helix move chips efficiently out of the bore. The h8 diameter tolerance ensures consistent, repeatable hole sizing for close-tolerance work. GUHRING Series 666 drills are a common choice for machinists, toolroom technicians, and precision assembly operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling aluminum and other non-ferrous materials, as well as general-purpose ferrous applications. The extra length design accommodates bushing applications where standard-length drills cannot reach. With a straight-cylindrical shank, it seats directly in standard drill chucks, collet holders, and drill press spindles without adapters. The 10xD flute-to-diameter ratio provides the extended flute length needed for deeper holes relative to the bit diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.1 mm diameter with h8 tolerance for close-tolerance hole sizing\u003c\/li\u003e\n\u003cli\u003eTiN coating extends tool life and reduces friction in aluminum and steel\u003c\/li\u003e\n\u003cli\u003e118-degree point angle with web thinning for reduced thrust and clean entry\u003c\/li\u003e\n\u003cli\u003e50 mm overall length with 28 mm flute length for extended reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flutes with regular helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard chucks and collet systems without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in bushing applications per the Series 666 specification and conforms to DIN 339 standards.

Secure the straight-cylindrical shank firmly in a drill chuck or collet holder before operation, ensuring the shank is fully seated and the holder is properly torqued. For best results at this diameter, use a drill press or CNC machining center with controlled feed rates to prevent bit breakage. Always wear appropriate eye protection and follow shop safety procedures when operating drilling equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 1.1 mm (0.0433 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.1 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 22 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 26.35 mm (1.037 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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\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\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Titanium Nitride (TiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: h8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, General Purpose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 666\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 339\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 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: 9006660011000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732644069682,"sku":"9006660011000","price":171.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e960411222b8f18359e4b0005d33d73_66fb195a-744b-499f-8216-1feef700c5a8.jpg?v=1788745364","url":"https:\/\/voomisupply.com\/products\/guhring-9006660011000-extra-length-drill-bit-1-1-mm-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
