That old-time standby, the ratchet drill, hasbeen displaced almost entirely by the electric powerdrill, except for emergency use and for certain classesof repair work. It has been found that the power drillwill cut the cost of track work in its sphere at least75 per cent over hand methods. By cutting down thenumber engaged on drilling the power drill has alsoreleased a large number of men for other work. Inci-dentally there is a saving in drill bits and cost of sharp-ening due to the uniformity of working conditionscreated by the use of the power machine. In hand workwith ratchets there is apt to be distortion in positionof bits and other parts created by careless handlingwhich lead to rapid breakage of bits. In connection with power drilling it should be notedthat there is a new type of power-operated ratchetdrilling device which is available for use wherever. A great crane that literallyeats up the work pneumatic tools are used in track work. This devicehas the compactness of the hand-operated ratchet andis available for use in cramped space at joint repairswhen the electric drilling devices cannot be used with-out destruction of a considerable area of pavement tomake room in which the apparatus can work. Regardless of the nature of the drilling device, thedrill bits receive very rough treatment, and the high•carbon steel rails in general use are particularly difficult to drill even with the highest grade of special tool-steeldrill bits. At this point the special tool-grinding ma-chinery of the portable type comes into service. Bymeans of special tool holders, any type of bit can beresharpened by the average laborer and the bits willdo better work than if sharpened by the average ma-chinist at a shop. There is no lost time waiting forfresh bits and a smaller stock can be carried, which isan item of moment whe
