For light work, this is perfectly adequate. For heavy work, I'd choose something better.I needed to cut a whole through a railway sleeper. I know this is not intended for such heavy work, but I was ready for drilling, then chiselling, drilling again, chiselling again etc. I managed it, but the saw bit is now blunted.And the "clever ejection spiral" (it's a spring!) flew off after the first cut. I don't think it was exactly essential though.This is perfect for plasterboard, or thin wood, but no more than that.

happy with quality & carried out task required for

Strong sturdy design, works better with Bosch pegged arbour.

Does a good enough job of cutting holes. I used it to cut holes in wooden desks for cable routing, only criticism is that there is no way to 'lock' the cutter in place and it has a tendency to fall off the mandrel as the hole breaks through.

Cuts perfectly on ceiling plaster and prepares it for fitting downlights.

Perfect for the job. Very pleased.

Quick Delivery. Cut clean holes without difficulty. Unfortunately, the centre drill is very brittle and sheared the third time of use. Easy to replace

Only needed for 1 hole in plaster and a through a bit of ply it did it’s job and will do several light work jobs. DIY
