11Pcs HSS Bi-Metal Hole Saw Set

It contains six saws at 22, 29, 35, 44, 51 and 64mm, and then the parts that make them usable: two arbors, one covering 14 to 30mm saws and one covering 32mm and above, an adapter, a hex key and a flat file, all in a blow moulded case.

Buying saws and arbors separately is where people come unstuck, because arbors are sized to bands of saw diameters and a customer who buys a set of cups alone frequently finds he has one arbor and six saws that do not all fit it. Two arbors covering both sides of the range solves that, and it means every saw in the case can actually be mounted.

The file is the item people ignore and it is genuinely useful. Bi-metal teeth dull with use, and a hole saw that has gone blunt does not announce itself; it simply takes longer, gets hotter and burns the edge of the hole. A few strokes of a flat file in the gullets, keeping the original tooth angle, restores a good deal of the cut. It will not rescue a saw with teeth stripped off it, but it will extend the life of one that is merely tired, and given what hole saws cost that is worth the two minutes.

Being bi-metal, high speed steel teeth on a tough alloy body, these cut steel sheet and section as well as timber, board and plastics, which is what separates them from the high carbon steel wood kits.

Buyers are electricians, plumbers, air conditioning and refrigeration fitters, panel builders, maintenance departments and hardware shops selling a complete starter set.
