Review on Precision Flute Straight Mills Cutter for Effective Home Tooling by Ahmed Rowe

I mill a lot of aluminum and these grooves are very good and not as expensive as the ones I've used but they haven't lasted any longer than these. The price is excellent, the durability is comparable to more expensive ones. I ordered an extra one because if I'm working on a project and it's a little chipped or worn I can just pop in another one and keep working. It's all a hobby for me, so the price is important.
