Ingco AKH012 Bi-Metal Hole Saw Set, 12 Pieces, 20-50mm

Our review

This Ingco AKH012 kit is a 12-piece bi-metal hole saw set covering ten cutter sizes from 20mm up to 50mm, which spans the diameters most often needed for pipe, conduit, cable glands and general installation work. Two arbors are included: a 1/4-inch round shank arbor sized for the smaller cutters up to roughly 1-3/16 inch, and a 7/16-inch hex shank arbor for the larger sizes from about 1-1/4 inch upward. Because the set is bi-metal, it is intended for cutting materials like wood, plastic and thin metal rather than masonry, so it suits electricians, plumbers, fitters and DIY users who drill mixed materials. Before ordering, confirm your drill chuck accepts both shank types and that the sizes you use most are in the range. Compare against single hole saws or smaller sets if you only need one or two diameters, and check whether you already own a suitable arbor. Available on Sokonia.
