b'High-Speed Holemakingand counterboring, not only save tool-changetimesbutdeliver greater accuracy because multiple operations can be performed in the same cycle.Successful holemaking depends highly on matching the drill to the correct toolholder. For routine op-erations, a collet holder is sufficient, but deep-hole drilling demands both increased strength and vibra-tion dampening.Weveseenagooddealof progress in conventional holders, Hobbs said. For instance, our ISO 9766 holder reduces the runout that you would find in a traditional Weldon holder. When it comes to deep-hole drilling, the choice would fall between shrink fit andAllied Machine & Engineeringa hydraulic chuck.
