When cutting soft metals such as aluminium and brass, a high-grade 1 Flute UP CUT Carbide End Mill for Aluminium is an excellent choice. This type of end mill is specially designed for cutting soft materials and has several benefits. First, it has the best chip ejection, which helps to prevent jamming that is common when cutting gummy materials like aluminium and brass. Second, it has excellent heat dissipation, which further reduces the risk of jamming and prolongs the life of the tool. And also it is more capable of operating with a wide range of feeds and speeds when slotting as compared to 2 and 3 flute end mills. However, if you're looking for a better surface finish on the sides and bottom of the material, using 2 or 3 flutes end mills is recommended. These end mills tend to produce a smoother finish on the perimeter of the cut.

Suitable for

Soft Metals (Aluminium, Copper & Brass)
Plastics (ABS, acrylic, HDPE etc)
Aluminium Composite Materials

Adam’s Tips

When cutting aluminium sheet, the type of cut that you use, whether it's a climb cut or a conventional cut, can affect the finish on the side of the sheet. It's recommended that you do some test cuts and evaluate which side has the best finish, then adjust your toolpath accordingly.

High-grade 1-flute up-cut carbide end mills are also suitable for cutting plastics. They are robust, but they don't have a sharp edge, which allows you to run them faster on plastic materials than a 1-flute end mill for plastics. However, it's important to keep in mind that this might only be suitable for cutting all the way through the material, and depending on the finish you require. On the other hand, a 1-flute end mill for plastics can give you a better surface finish but at a lower cutting speed.

1 Flute UP CUT End Mill (for Aluminium)

Posted by Damon SIgns on 8th Dec 2022

I love Adam's Bits. When I first found them I was like "oh yeah another *yawn* bit supplier", but I soon saved the Catalog, with all its useful information, to my drive for constant reference. The 'Good For', Great For', etc info is so useful. And the bits themselves, NEVER a problem. They seem to last a lot longer than certain other popular brands I've used, and zero breakage. Can't praise the hardware, or service, enough.
