## Description

SICWOOD Slab Flattening Router Bits 1/2 Shank, 2-3/8”Cut Dia, 12*12*1.5mm Insert, CNC Spoilboard Surfacing Router Bits, Planing Router Bits, for Flycutter/ Slab Leveler/ Rabbeting

Review: The picture shows the aftermath of creating a 1/2" slot against a 2x4 framing to secure the 1/2" PVC bead & board panels for the front steps I'm building currently. Because this panel design was an afterthought, some of the 2x4 pieces were too secured to use the table saw to create the channel. With that said, I took out some wood screws where I had to make the channel and by accident, I missed a few and instead of the cutter head getting demolished, it ate through the screws heads that weren't taken out. So there were some chipping that occurred on the blades, but this is after zipping through 4-5 epoxy coated screws. I was very pleased with the results. I also love this design like the spiral head cutter on a planer as I can rotate it. And the cutters are replaceable so it's well worth the money. I'm using this also on Bosch router. Important: I'm not sure how people are destroying the cutterheads fast but I made 3-4 passes to reach the 1/2" depth. You never want to cut anything deeper than 1/8" at a time as it can grab the piece hard or make it go in different directions. Speed was at the maximum (7 on my Bosch). Considering this was relatively wet pressure treated wood, I'm very satisfied with the results! Very durable router bit 👍
Review: Very pleased with this bit. I have been using a standard 2 flute bit to flatten slabs with decent results but this bit far exceeds anything I've seen.

Worked great on my walnut slab. Clean cut and stayed sharp. I will probably get a larger one to cut down time.
