It covers a vast range of workpieces, is very easy to handle and of robust structure. It is cost effective to use the drill for one-offs as well as for small batches.The machine is particularly suited for workpieces where tolerances required are simple and not close. Three feed speeds and two spindle speed ranges, each providing 18 spindle speeds, make the alpha an ideal drill for all standard applications.
