Professional Double Flute Straight Router Bits 1/4 Inch Shank, Flush Trim Router Bit Set, Cutting Diameter Respectively 1/4", 5/16", 3/8", 1/2".

These bits were used to trim the edges of composite deck boards, which can be notoriously finicky and subject to damage. The varied sizes made it easy to tailor my work to the difficult thicknesses I encountered on landings, stairs, and the deck body…every size executed smooth cuts, even after extensive use. These have become some of my new favorite tools…I often use them for cutoff jobs where I previously used saws and then had to finish the edge…now I get a smooth finish in one motion.

I needed a flush trim bit in a hurry and Amazon offered next-day delivery on these. I didn't expect them to be of very good quality given the price. However, I was quite surprised. These did the job and did it well. The cutting edges held up very well showing no signs of wear. The bearings ran smooth and quiet and did not heat up. I was cutting tempered masonite with these and the cuts were extremely clean.

These look like they are built well but I have not used them yet that's why they get a 4. Blades are sharp

These were just what I needed. Nice and sharp and I needed the extra depth for my project. Very happy with these and at the right price. I recommend them.

Worked well.

Dull right out of the box wouldn’t even clean cut OSB plywood. Try to put any pressure on the router it would bog down and turn off. Then two minutes into using it the bearing fell off the top and router went crazy. Save yourself a headache and get a nicer set.

These bit were excellent during my recent project.

Excellent value for what you get. Not as sharp as the big box store ones but they also cost four times as much for one.
