I'm just finishing up a 3rd door made with the MLCS set. I got the Katana bit,
since it came with the 1/2" cutter. Work great with my Milwuakee 3+ hp router.
The first door was a full 1 3/4 entry door, and I'm now doing several 1 3/8
interior doors to match up everything on the main level of our house. The bits
cut very clean, joints are well matched, and I'm able to make the cut in 2
passes - 1 heavyfollowed by 1 light to clean up the edges. The stick cutter is
one major hunk of metal - and needs to be run at the lowest speed (8000 rpms?).
Also, when changing out the 1/4" for 1/2" cutter, it seems to be pretty
critical to line up the cutters to minimize vibration (DAMHIK). The set was
pretty pricey (around $180 as I remember), but more than paid for itself in
just the cost savings on the entry door.
