                                                                                   Aluminum-cutting
                                                                                   endmill.











                        shop. This makes it possible to mill aluminum if an endmill, like
                        the one shown in Figure 1.6, is purchased from a machine shop
                        supplier.  The  drill  press  can  then  double  as  a  small  milling
                        machine.

                        You will need a set of drill bits like the ones pictured in Figure 1.7.
                        The 5/32-inch and 1/4-inch drill bits are used most often during
                        the projects. You will need to separately buy the small 1/32-inch
                        and 3/64-inch bits that will be used to drill the component holes
                        in the printed circuit boards.
