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)

I used this flush trim router bit to trim the lid of this jewelry box flush with the body of the box. See attached photo. Previously, I have used flush trim router bits with a straight cutting edge. This router bit has a spiral cutting edge and it seemed to have a smoother cut than my previous bits. Also the spiral cutting edge seemed to pull the workpiece down onto the table, also giving a smoother cut without any of the chatter you can see with a straight cutting edge. Overall this router bit does what its supposed to do and I highly recommend it.

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

Needed an upcut/ downcut 1/4 flush trim bit, bought one each. Only used the downcut so far, but it meet my expectations

Glad i bought the two pack and had an extra template. Failed after 6 cuts. The second but did fine for this 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.

It worked great for cutting out windows in drywall.

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.

This seemed like a good value for a template routing bit. I used it on three very small projects It cut through the oak like butter! But as I started the fourth small project the bit broke. No more cheap bits for me! Now I’m stuck

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

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.
