. Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . CUTTER FOR VERTICAL MILLER closely approaches a point, but has itscutting edge protected by ample side andfront clearance and back and side rake, I \ I 1. WHEEL BORING TOOL an angle of % being used at each of thesepoints, so that the cutting qualities are asgood as possible. The side tools are made on thesame general principles as the counterboring tool, but with the variation inshape that their work requires. Cutter He.\d for Vertical Miller The very sturdy cutter head shown inthe illustration is used on a vertical millerfor a variety of heavy work. It carries55 cutters set in eleven horizontal planes,with five cutters in each plane, each ofwhose cutting edges overlap those of theplane above and below. As will be seenfrom the dimensions the head sets overthe tapered end of the spindle and isdriven by a 5-15-in. key. The cutters themselves are of y^ steel ground to the cutting shapeshown in the side elevation, with a cut-,ting face V% in. wide and tapered back back at flie rate of .007 in. per inch oflength. Such a cutter is capable of doingvery rapid and heavy roughing work. Wheel Boring Tool This is a heavy tool or rather too
