Good quality and value for money
I wish I used these before to surface my projects before starting the CNC carving. For the time it takes to surface the project, it makes such a difference when using rough sawn timber. They also fit both my 1/4" and 1/2" hand held routers too, when using the supplied sleeve for the 1/2" router. For the hobby user and the DIY user these are ideal, the price and quality of the product reflect this. Professional and industrial users would obviously opt for a more expensive and higher quality router bit.
