well they dont come with extra points and dont fit pencil lead so WHY are the collets not tight?!? i then had the top part fall off from unscrewing in my toolbox. I thought thses would be great as i could use stainless steel 1/2" or 3/4" banding for my beam as you dont find wood 3/4"by 1 1/4" laying around that often, and a carryig a wood beam around on a contruction site is not feasabel and would get broken in toolbox. the odd part it that its beveled on one side and not other so i would have to cut into it with a hacksaw to hold that 22 ga. banding. oh..does anyone have a 24" compound square? otherwise..dividers would be alot easier. they dont open wide enough for a rule. If you were in a shop and had small steel bar could work out, but in that case i would get starretts or stanleys that have more surface area
