For small work, twist drills with square shanks for brace use should range in sizes from one thirty-second of an inch up to one-quarter inch, then every one-sixteenth inch up to one-half inch.
For boring screw holes in wood the quickest work is done with pod bits. Not many sizes are needed, but they are cheap, so that a half dozen, ranging from one-sixteenth to one-quarter inch or thereabouts, will be found very useful. Pod bits belong to the wood department, but on account of being used principally for screw sinking, they are just as useful in the iron working department as in the carpenter shop.
Sheet metal snips for cutting sheet metal properly belong with the iron working tools. Snips are from ten to fourteen inches in length. A medium size is best for miscellaneous work. If kept in good working order twelve-inch snips will cut 18-gauge galvanized or black iron. But a man would not care to do a great deal of such heavy cutting.
