Built to DIN 1897 standards, it measures 0.209 inches (wire size No. 4) in diameter with an overall length of 2-19\/32 inches and a parabolic flute length of 1-7\/64 inches. The 130-degree split point and web-thinned geometry reduce thrust and improve chip evacuation, making this bit well-suited for high-volume hole-making where speed and precision matter. Construction is high speed steel with a bright uncoated finish. Right-hand cut with a straight cylindrical shank.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is intended for use in screw machines, CNC machining centers, drill presses, and turret lathes where a short, rigid tool is preferred over jobber-length bits. The primary workpiece material designation is aluminum, though the high speed steel construction handles a range of non-ferrous and ferrous materials in typical shop applications. The compact stub length minimizes deflection in applications with shallow-to-moderate hole depths. Maximum drilling depth is 0.789 inches, with a 3xD flute-to-diameter ratio that aids chip clearance in shorter cycle operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1897 specification for consistent dimensional standards\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes efficient chip evacuation and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with web thinning lowers cutting thrust\u003c\/li\u003e\n\u003cli\u003eStub length provides rigidity and reduces deflection in production drilling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003cli\u003eParallel web configuration with straight cylindrical shank for standard chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length replacement drill bit for use in screw machines, turret lathes, CNC machining centers, and drill presses accepting a straight cylindrical shank in the 0.200 to 0.250 inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinist or toolroom personnel.
