Great value cuts ply, MDF plasterboard easily, bought for down lights but has been used for several other projects due to size, great for making a hole in a stud wall to feed stuff through that you can get both hands inside, cuts clean and easy to put cut piece back in a fill over, go slow and don't push hard or wobble as gets jammed but just restart and cuts through great

Excellent did the job.

Good value!

Seems very well made and strong. Did the job no problem when cutting holes in the bathroom ceiling to fit spotlights/droplights in; whatever they're called. Slots right into a normal drill, so no need to buy a big corded one etc. Very handy.

The desription says it will cut metal, well it doesn't. I am trying to cut 0.5mm sheet metal. It just scratches the surface.

Did job perfectly. Would purchase again .

Bought this to cut a hole in a polyurethane ceiling rose, to fit up a new led ceiling light. Did the job accurately and cleanly.

does what i need it for.
