SpeToolW05003CNC router bit comes with 4 wings and can be cut within 2-½ inches diameter. Though the shank size is similar to the previousW05002router bit, its cutting diameter is larger than that.
A hard surface doesn’t mean a wooden surface only. Its cemented carbide blade can flatten every wooden surface including soft and hardwoods, MDF, plywood, laminate, and many more.
Key Features:
The blades are suitable for timber surfaces.
Its extremely low vibration increases the cutting efficiency.
It doesn’t leave any burn marks on the surface.
Contains two cutting flutes and two up-shear scorers, which provide a smoother finish at the bottom of the cut than traditional two-knife style router bits.
Blades are replaceable and can be used for a long time.
Instead of making my own, I purchased this because of the lower price, adjustable height, low weight, quick set-up, and easy storage. It was delivered well packaged and directions (along with their video) made assembly fairly straightforward. To date I’ve only flattened one 8 foot slab. I took the time to make a base out of 2x4s and use sawhorses. The router plate didn’t fit my Bosch router so I had to drill holes. It did as advertised.
My disappointments are the slight flexing of the aluminum extrusions while routing, and the amount of sawdust build-up under the wheels. I’m hoping to improve on this. I did use compressed air often. Overall, it meets expectations for an entry-level sled.
Four stars
I had hand surgery right after I ordered the fly cutter so I haven't been able to use it just yet. But the balance and the way it was designed I think it will work good. Here in about 2 weeks I'll be able to try it and will add to this review.
The price and delivery were good. I used this bit on my small CNC to surface some ash slabs about 2' x 2' x 4" thick that were chainsaw cut. I was not cutting end grain. It worked very well at 18k, 0.10 deep with 24% stepover. After cutting 4 of these faces I could tell the cutter was probably dulling a little because there was more heat in the cut. I did clean the carbide cutter surfaces after each cut. I would purchase this bit again.
