Kreg frez prosty 1/4" - trzpień 1/4"

I was skeptical a 1/4" bit could handle repetitive grooving without burning, but the carbide tips stayed sharp through a whole shelf unit’s worth of dadoes. Shank fit my compact router perfectly with zero wobble, and the cuts came out clean enough that sanding was barely necessary.

Took this little bit out for some dado work with my trim router and the 1/4" shank locked in perfectly with the guide. Cut clean, no burning, and the carbide edge still looks fresh after a good run. Exactly what I needed for edge routing without swapping tools.

The carbide tip cut through my oak shelf like butter when I was routing a groove for the shelf pins, and the 1/4" shank fit snug in my compact router without any wobble. It's held up through a full set of dadoes without burning the wood, which is more than I can say for my last bit.
