Customer Reviews

1/4 in. Down Spiral Bit is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Fantastic Cut - effortless !!!! Outstanding results after trying other bits that really labored doing the same job. I used mine for making 3/8" deep slots in rail and stiles for flat panel doors using a Kreg jig. It was important to get a super clean cut and to be able to dive in and stop and pull out. No Issues - like butter. The other note is I was using a fairly small inexpensive router (1/4" collet) and table so the bit shined on its own. Really impressed and it got the job done with ease!!!!
