SpeTool 1/16 inch Cuting Diameter Spiral UP Cut Router Bit with 1/4 inch Shank 2 Flute Plunge CNC End Mill

Great

I bought these bits for some acrylic and wood CNC projects. Wow, these are some cheap junk! They broke off almost immediately. Even a very shallow and slow passes.

Very sharp. So far so good. I use these in my CNC in soft woods and keep the speeds and feeds pretty low.

I was actually surprised how well it worked on my project i did today was kinda waiting for it to snap in half any minute but it actually did really well through out the cut I ran it at 55 ipm wuth no issues

Its small and cuts cleanly. I cut slots in roasted maple guitar tops, 1/4-inch thick tops, and the slots are perfectly routed by this bit. Its long enough to cut through the thickness, and does the job easily. Highly recommended.

Broke after 30 minutes of use

Snapped in half cutting a 1:16th tool path at 175 mm/min which is below Rex speeds/feeds will not buy this brand again
