CMT 806.690.11B Flush Trim Bit with Double Bearing, 2-Inch Cutting Length and 1/2-Inch Shank

I wanted to put smooth edges on oak stock that I was using to make red oak mission style chairs. The back legs are 1 1/2x 1 1/2, with a angle about half way. Several of the cross pieces have an arch cut. I made a template of 1/4 mdf. I cut the pieces on the band saw, cutting about 1/8 outside the lines. I got this two bearing CMT cutter, installed them in the 2hp router mounted in owner made router table. It is an awesome, serious, massive bit. The length handled the 1 1/2 stock plus the 1/4 template and took the saw blade marks out, leaving a smooth finish, no sanding needed. The two CMT bits I ordered came in a sturdy bit holder and a heavy clear plastic storage box. Once you get used to the large size, you should enjoy using these bits. They are well made, sharp carbide cutters, smooth ball bearings, the bottom bearing is removable, when one needs to make a over cut with hand held router. I am a hobbyist, not a pro, but for what I wanted, these bits suit me very well. I am looking forward to using them some more, they are fun to run.

Does everything we needed it to do. This seems to be a very sturdy bit. Worth every bit of money we spent.

This chewed through some 2x4s I needed to trim very easily and with no splitting.

I bought this bit for template routing to make some back chair legs. I was VERY surprised at how well this thing was able to cut down a 2x4. Super smooth and hasnt dulled at all after a fair bit (no pun intended) of usage. It is a large, solid, well-built router bit and it got the job done!

Gets the job done. Has maintained its edge throughout many passes on 1.5 cherry.

The bit made nice clean cuts. One thing I didn’t consider is that I thought the extra length compared to other bits was a plus, but the bit is so long that it can’t be lowered enough for the top bearing to ride on the template when cutting 3/4” stock using my Bosch router and Bosch router table.

I used this bit to shape some ash. It did the job, but afterwards I checked the bit and half of it was severely damaged. I want trying to push too much wood through. One and done I guess.

Exactly what I needed for smooth edge trimming. Staying down grain for the best pass when traimming.

This is a large bit, so you need to reduce router speed when using it. The top and bottom bearings make it suitable for pattern following and/or edge trimming. Generally CMT makes excellent bits, so I expect this to last. I am retired and a DIY woodworker and I am in my shop pretty much every day, so my tools and bits are used frequently. Not a production shop, but not quite a weekend warrior either.

Dead on accurate. It’s a long bit make sure your router or router table has enough travel to get the bearings against the template
