02-06-2025Looks like a quality bit, but cut quality is terrible. Not sure if I just got a bad one, but it’s useless unless you want to sand forever.

> 3 dayI really hate having to say anything negative about SpeTool as I have used plenty of their products in the past and have been generally very satisfied, but this thing was a very fast waste of money. Decided to test it out in a thin piece of pine at low feeds and shallow doc, and the end mill snapped within the first 30 seconds! Most likely will not buy again!

THE O FLUTE ROUTER BIT
Why choose O Flute
Compared to other flute styles, the cuts are cleaner, plunges are deeper and chips are easily directed up or down, depending on the type of spiral you choose. If you work primarily with plastic or aluminum, you’ll be happy to learn that heat is dispersed more easily with the O flute bit and it stops weld back
When choose O flute
If your material has a low melting point, a Single Flute Plastic Cutting End Mill is a good option. This tool has a larger flute valley than its two flute counterpart which allows for bigger chips. With a larger chip, more heat can be transferred away from the material without it melting
