As a result of using this product, I found that it greatly improved the precision of my milling operations. The flute speed steel is of high quality and is durable enough to withstand the demands of industrial and scientific settings. It cuts smoothly and helps prevent vibration during operation. However, the product can be a bit pricey compared to other options in the market.
Pros
Improved precision, high quality and durability, smooth cutting, prevents vibration.
Cons
Price can be a bit high compared to other options.
Great price for it. They cut well. Machining low carbon and some harder steels with shallow depths of cut. I've already broken a flute through my own fault.
I have these 3 out of 5 because they do what they are supposed to, just not well. I've tried milling steel and it's really not very good. I would suggest them for aluminum or something softer. Came very sharp and in a nice wooden holder.
