Suitable for general work, drill bits are not quite straight but suitable for rough work. I lost a box of countersinks when we were moving and didn't want to buy another expensive set as I figured I'd have to find them eventually. This is a good value for an all purpose set. The drill bits are not exactly straight but very functional for normal use in a hand drill. I used them in softwood and alder until I found another CS. I will keep them for general use.
