The Hydra was a many headed water serpent/beast. Whenever one head was chopped off another one grew back in its place. To slay this dreadful beast was the second of Hercules' twelve labours. This was an enormously difficult task, since every time Hercules succeeded in cutting off one of Hydra s heads, two would grow where the one had been. Hercules finally killed the Hydra by burning each neck stump immediately after severing the head, thus preventing any regrowth. Our can tackle your toughest operation with many heads - one body!

DRILLING WITH COOLANTS For maximum chip ejection and tool performance coolant must be used with the Hydra-Drill. coolant mix of 6-8% is recommended for most applications. Use a higher 10% mix for high strength steel, stainless steels and tougher drilling applications. When using coolant fed drills, a coolant pressure of 150 PSI or higher is recommended. FAVORABLE CONDITIONS Internal coolant holes provide improved web strength and deliver lubrication on cutting edges for increased productivity and longer tool life. DRILLING EFFECTIVELY WITH S Holders: Tool holders and collets must provide good concentricity between the drill and the machine spindle. Use a positive back stop to prevent the tool from backing up into the holder. Static runout in the tool assembly must be accurately checked and maintained. Workpiece: A secure and rigid workpiece to minimize deflection is needed, particularly on through-hole applications. Speeds: S are run at substantially higher speeds than high speed steel drills. Feeds: The feed rates for S are normally comparable to that of High Speed Steel drills. It is important not to underfeed the drill which will cause it to dwell and dull. This is particularly true in work hardening materials. Entrance or exit on an angular surface Drilling through cross holes Interrupt at exit In these drilling scenarios, reducing feed rate to.004 -.006 IPR is generally recommended. To determine speeds and feeds for your applications, please reference our easy to use Application Material Groups (AMG) chart on the back cover. 4
