Upcut Spiral Flush Trim Router Bit, 1/4 Inch Shank Solid Carbide Flush Trim Router Bits Spiral with Nano Coated by EANOSIC (1/4 Shank Up-Cut)

It worked great for cutting out windows in drywall.

This bit is a great value. Good quality and leaves a great finish. I like the coating.

I used this to cut starboard and after probably 20+ feet of cutting seems to still be sharp and the bearing has not failed

If youve never tried them, seriously, get one now. Ive always used flush cut bits. Decades, still used flush cut bits. Until I decided to try one of these. Ill never go back to regular flush cut bits. These are amazing. Ive run dozens of passes using these bits, and they still throw perfectly blade shaped chips like slicing a potato. The correct up/down bit will hold your work against the surface if youre using an overarm router or fixed base router. In a word, the right bit, and theyre perfect. Only suggestion I can give for outstanding performance is to trim whatever youre working on as close to the final shape as you can. They will cut with full contact like going through a board to cut out a pattern. But, trimmed close they glide through like butter and wont pull away from what youre working with. I bought several of each, and Ill never go back to straight flush cut bits.

A well made router bit. Not sure what the blue coating does but the bit holds up the job well. Tens of meters of trimming so far. Nice :) I will buy it again when the next project pops up.

Ended up using this to work with some cutting board cutouts. This worked pretty well to template and cut. It was also not nearly expensive as more premium brands. Seemed to cut just fine!!!

This bit cut fantastic for about three pieces, on the fourth piece it broke. I’m disappointed and now my projects are behind. If the seller could contact me, I would appreciate that. I bought this about 8 months ago but just started using it a couple days ago.

I usually use less expensive bits but Im glad I went with this one. It cuts very smooth and clean. Great Bit!!!!

i was very impressed, but only used it for one small project.

What an awesome trim bit. I use it for cutting tabs off of CNC carvings and also for template routing and it leaves absolutely smooth lines on the cuts. I would highly recommend this bit to anyone who is in need of a trim router bit.
