Go To Small End Mill

This is my "go to" small end mill. I can be pretty aggressive with my speed/feed and have never broken one of these. They have good cutting endurance, provide consistently smooth cuts and haven't let me down.

Speed and Feed!

Bit was as described and worked perfectly! Sharp and smooth cut

El wayo
excellent! great buy

love the material and excellent customer service! these are great! and for a good price!
I use them a lot for my small cnc projects, my personal fav is the compressions bits! wow! there amazing and strong!

worked very well

Product for now seem to work very good.

Quickly became my favorite bit in my Shaper Origin!

I like to cut signs (and intricate pieces of signs) with my Shaper Origin, and this bit can get into sharp corners much more effectively than other bits (like the 1/8th or 1/4 inch).
Ive started working with 2.7mm plywood, and this bit can easily cut it in one pass, and as its a down cut bit, it seems to minimize the sanding needed on the top edge (which is a big deal for me).
The bit is a little pricey, but this far Id say Worth every penny!
