Wood Owl has specialized in drill bits since 1923 in Miki, Japan, and this is their Tri-Cut auger in the compact 7-1/2-in length. Each bit is milled and ground from a solid steel blank rather than cast or forged, so it runs perfectly concentric with almost no wobble.
Three precision-ground flutes, cutting heads, and spurs work together: the spurs score the hole rim before the cutters clear the waste, leaving smooth, accurate holes with minimal blowout. The shorter length is easier to control and lives happily in a drill bag, and it comes in fifteen diameters from 3/8 to 1-1/2 in.
