Industrial holesaws with unique features and benefits. Cut wood, plastic and metal including stainless steel (with coolent). Made in Bosch's Swiss factory, the toothed edge is made with extremely hard wearing 8% cobalt alloy and the teeth cut with Bosch's unique progressive tooth geometry. These holesaws will give virtually unrivalled performance in a wide variety of materials, even stainless steel, cutting depth of all holesaws is 45mm. The holesaws simply click into the arbor, changing from one size to another can almost be done in a fraction of a second. No more holesaws jammed or seized on the arbor. Arbors available separately.

Worked for meBought a set of these for odd jobs and they have worked very well. I've used the 38mm saw to cut 3 holes in a steel beam 6mm thick and the teeth are still as sharp as at the beginning. Used a little oil and slow speed (about 250 to 300 rpm) and each took only a minute or two to cut. The only nuisance with these is that they are slightly too short to cut a hole in 45mm timber wall studs without having to knock the plug out for the final few mm. Also when cutting wood you need to clean the teeth out regularly and then they cut very quickly - don't just lean on them harder!

Don't bother - get an IrwinI hae used a set of the bi-metal hss holesaws for plenty of wood and plastic jobs. I bought them (not cheap) as I am a plumber and the fact that they advertised them as able to cut stainless/mild steel etc. 2 cuts of 6mm mild steel with the 15mm holesaw and the teeth are wrecked. I used a proper pillar drill set at the normal slow cut speed for steel (I also do steelwork/welding). I had to go out and try to replace the cutter but could only find the Irwin equivalent which I bought (the job had to be finished). Fantastic - did the job and has continued to do more mild steel without compromising the teeth. I won't bother with the Bosch ones again. As they wear out (which shouldn't take too long if the last one was anything to go by) I will replace them with Irwin tools.

A league of their ownWhen making small items in stainless 316L, for deck hardware and such, these holesaws are the only ones that will not wear out instantly. Do use a pillar drill and lots of cutting fluid, of course.
