Great Bit!
I use this on my Genmitsu PROVer Xl 4030 with a Dewalt 610 pocket router as my spidle. It cuts awesome at 24,000 rpms. A nice clean cut. I'm very happy with it. This bit replaced a more expensive bit and works better. This bit is in Carveco's tool database. I rounded this clock with this bit.

Clean cut, no rip out or tearing
I purchased this to cut a 3 ft circle out of plywood. Made two passes and no rip out. Very happy with results as it was for a school project for kids and didn’t want them to get splinters. Light sanding to softened edges.

No problems, good quality
Perfect bit for my application. Well made and good quality. Appears durable and was good at cutting my TREX decking to tidy up my picture frame corners

Sharp bit that does a clean job
Used this bit to cut a 1/2 inch deep trough in a very hard oak tree trunk cookie. Cut was clean and smooth using a hand held battery operated cut out router. Not really the tool to use for such a thing but the bit made it happen and made fast work of it...

Good Roughing bit for wood
I use my CNC machine about 50 hours or more a week. So far this bit alone has lasted a week. It's still cutting. I will end up buying allot. I like how they cut.

Great bit! Great price! No issues at all!
Amazing product so far! I use this bit on my Shapeoko XL and needed a new 1/4” bit for cutting out profiles. As you can see in the picture, this bit was used on the left plaque and my older Amaña 1/4” downcut bit was used on the right plaque. As you can see the difference, if you zoom in, this new bit is far superior to the amana. But the amana bit is older and most likely slightly dull as well as being a downcut only bit. But I’d have to say that I’m very pleased with this “Spetool” compression bit. Perfect bit!

Great Performance
This bit performs exceptionally well on plywood, was totally amazed by it's smoothness of cut. Use their 1/4 DC bit as well, will definately continue using this brand.

Buy something better….
Cuts nice and clean….for a bit. Then they just lose edge and burn. Not worth it. I purchased three and as a hobbyist using them maybe a couple hours per week total they’ve failed.

Im using on my palm router. It cut wood like butter . Buy it for your router its better than the actual router bit.

Tried this as a less expensive alternative to a name brand bit and very impressed with the results. After about 15 hours of cutting the bit is still sharp, producing clean defined edges. No chatter, even deeper cuts on maple. Tried in a variety of soft and hard woods, all with great results. Definitely recommended for any CNC application.
