Jonathan's Hot Take:

Compression flush trim bits have quickly become my absolute favorite type of spiral bit. It gives you super clean edges on both the top and bottom, which is amazing for flush trimming. These are great for getting into tight turns and have a spiral for every occasion.

Typically, companies have had a tough time making a flush trim bit this size because of the bearing limitations. Bits&Bits and I came up with these special bearings to combat that problem.

These bits provide the HIGHEST VALUE because the Astra Coating makes them last at least 2-4x longer than uncoated bits. This is one of those times that spending a little more upfront saves you a lot of money down the line.

Spiral bits perform 100x better and 100x longer than straight bits. I recommend staying away from straight bits in general, because they dull so much faster and their aggressive cutting profile can be much less safe.

Check out the video in additional resources for more info.

These solid carbide flush trim router bits feature compression flutes, which combine up cut and down cut action into one bit

    Awesome product!

    I recently used it to build some toys for Christmas. 16 toy cars (hard maple and cherry), the bit went through the wood like butter and stayed sharp the whole time. Great product, one of my favorite bits to use. The length is really good, and considering how thin it is (which is why I got it, to pattern tight curves) I couldn't notice any flex whatsoever.

    It's "Astra Coated"

    This 1/4" flush trim bit is unbelievable! It just glides along flawlessly. It produced a nice clean, crisp edge with a perfectly smooth cut along the face. Impressive!

    Very good router bit

    Overall I really like this bit. Cuts cleanly without effort and very smooth bearings. My only reason for not giving it five stars is that it struggled a little with anything over 1/8" of material. Easy fix is to get the 1/2" version of this bit, which I did.
