Expansive Bit 22-76mm
This was cheap, but very poor. Bought for cutting holes in 1/2 inch chip board- shredded the board to bits. Tried on hardwood with same results. Avoid.

I bought this bit specially for a project that I have not started yet. This expansive bit is not well designed. In fact it will be impossible to use in thick pieces of wood. My intention was to drill holes through beams to put a wash hand basin waste pipe under the floor rather than round the walls. At the desired size the tail of the bit will not pass through the hole that is drilled so you will never get through the wood. Nothing a good angle grinder will not cure.
