This 150mm bi-metal hole saw has been excellent for my DIY projects and some light professional work. The HSS teeth are sharp and durable; I’ve used it on wood, drywall, and even aluminium with smooth, consistent results every time. The cut edges are clean with minimal need for sanding or touch-ups afterwards. The 30mm cutting depth is more than enough for most domestic jobs, and the hole saw feels solidly built—no flexing or wobble during use. Attaching it to my drill was easy, and it stayed secure even under heavier loads. If you need a reliable large-diameter cutter for extractor fans, ducting, or large pipework, this tool is a great investment. It’s held up well after repeated use, and I’d definitely recommend it to anyone needing a quality hole saw for various materials.

A good hole saw at a very fair price. Have used it to cut holes in marine ply, epoxy/glass matrix and GRP and it has remained sharp throughout.

Cut the hole in the van roof just fine

Cuts ok only used on plastic and wood the spring waste push out unit did not work on the materials and thicknesses that I was working with ( making nest boxes)

A great little hole cutter with the added bonus of a central spring which makes removal of the cutout as simple and easy as possible.

To be honest for the price little thing cut well, I only cut out 5 holes and it stayed the course.. for price I’d buy another

but the teeth seemed to burr off when cutting a tap hole in a graphite sink...to be fair it doesn't state it's intended for cutting this material and it eventually got through and left a very tidy hole so for the money it's done the job for minimal outlay.
