Sized at 0.177 inches (wire size 16) with a 130-degree split point, this bit cuts aggressively through titanium alloys and other hard-to-machine workpieces. The parabolic flute geometry promotes efficient chip evacuation and reduces heat buildup in deep-hole applications. Web-thinned construction lowers entry force, and the parallel web configuration maintains rigidity along the full flute length of 0.945 inches. Built to DIN 1897 standards, this is a heavy-duty tool intended for production and maintenance machining environments where tool life and dimensional accuracy are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for use in machine shops, MRO facilities, and manufacturing environments where titanium alloys, stainless steels, and other high-strength materials are routinely machined. The stub-length body reduces deflection in short-reach setups, making it well matched to screw machine, CNC lathe, and drill press applications. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With a maximum drilling depth of 0.679 inches and an overall length of 2.283 inches, this bit fits compact tooling setups where rigidity matters as much as cutting performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for extended tool life in hard and abrasive workpiece materials including titanium alloy\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle for fast, positive engagement and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes chip flow and cooling in interrupted or deep cuts\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, parallel-web construction balances rigidity with reduced entry force\u003c\/li\u003e\n  \u003cli\u003eStub length body minimizes deflection in short-reach and screw machine setups\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1897 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897 Series 659 stub-length drill bit with a straight-cylindrical shank; fits standard drill chucks and collet holders accepting 0.177-inch shank diameters.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet. Verify shank seating depth and chuck runout before beginning a cut, as excessive runout reduces tool life and hole accuracy. Do not exceed the recommended maximum drilling depth of 0.679 inches per the manufacturer geometry rating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.177 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.283 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.679 inches\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: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 659\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 9006590045000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732140327218,"sku":"9006590045000","price":25.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39f9eaedf19e6503720f793a9c0b52f5.jpg?v=1788739662","url":"https:\/\/voomisupply.com\/products\/guhring-9006590045000-cobalt-drill-bit-0-177-in-stub-length","provider":"Voomi Supply","version":"1.0","type":"link"}
