A third style also exists, a lighter, much more functional machine, named a mill-drill. The mill-drill is a close relative with the vertical mill and very popular in gentle industry; and with hobbyists. A mill-drill is similar in basic configuration to a very significant drill press, but Geared up using an X-Y table and a much larger column. Additionally they generally use additional potent motors than a comparably sized drill press, most are muti-pace belt driven with some types having a geared head or Digital velocity Handle. They typically have quite heavy-responsibility spindle bearings to cope with the lateral loading over the spindle that is created by a milling Procedure. A mill drill also typically raises and lowers the complete head, which includes motor, often on the dovetailed (often round with rack and pinion) vertical column.
