Review: Works great for signmaking with the Rockler State Park kit - Love this bit and it does a great job in conjunction with the Rockler State Park sign kit. I used a standard rounded router bit previously but this one with a flat "bottom" works better and looks great!
Review: So far they’ve performed well and remained sharp. - I’ve only used the bits for a couple of signs so far. I’ve routed through some oak, pine and maple. Also through some wood I repurposed from an old pallet. So far they’ve performed well and remained sharp.
