I need a router set to create long grooves for joining biscuits without a special biscuit joining tool. This set of blades has the ones I needed, specifically a size 5/32, which is the standard size for #1 biscuit joint. I used these to attach a maple footboard to a bench seat, and the blade made a nice, even, clean cut. with my hand mill. The blades can be stacked to make wider/custom cuts making this set particularly useful. This is a set of blades that are used a lot in my woodworking…
