4-Pc. Three-Flat Step Drill Bit Set, High Speed Steel, 31 Hole Sizes, 1/8 In to 1-3/8 In is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from This set says that it drills holes up to 1/38” but doesn’t include a bit that has that capability of drilling that size hole, the largest largest hole it can drill is 1 1/8” so please read the fine pint before ordering if you have the need to be able to drill 1 1/3” holes for 1” conduit
