Spiral Flush Trim Router Bit 1/4 Shank by PROMSA, Ultra-Performance Compression Top Bearing Router Bit, Solid Carbide Trim Router Bits, Flush Cut Router Bit for Wood Trimming, Up-Down Cut

This bit has helped me with tear out when routing the edge of boards. I was using a straight edge trim blade and often experienced wood chipping especially at the edges. This bit is very sturdy and does exactly what I need it to do.

I have a lot of flush trim bits but, since I work with a lot of hardwood, they dull easily. This one rips through hardwood with ease and, since you can replace the blades, should be useful much longer.

This is a great bit. There are two cutting blades that can be rotated 90º when one side gets a little dull. At first I thought they were the same as the blades on my Wen Planer (would have been convenient) but they are slightly smaller. Still, you can rotate the blades so you have four edges to work with before needing to replace them. The bit works as described and does a great job!

Love this router bit for making wood patterns for making wood signs.

So, yes, out of the box the cutter did excellent. I rough cut a couple of boards to shape and used a quarter inch thick template and this carbide insert flush trim to finish them off. For me personally this bit will have limited use in my shop since the cutting length is so short, just under half inch. I have many other flush trims, solid carbide, up/down cuts, compressions, etc, all of which are over 1 inch length and make template cutting much faster for thicker lumber. Overall, I cant complain about the bit, because Im sure there are folks who need to flush trim signs and other thin material all day long, but if you are looking for good, versatile flush trim, that will work on thick and thin material, there are much better options out there.
