When cutting soft metals such as aluminium and brass, a high-grade 1-flute up-cut carbide end mill 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.
- Soft Metals (Aluminium, Copper & Brass)
- Plastics (ABS, acrylic, HDPE etc)
- Aluminium Composite Materials
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.

Very fast delivery, excellent quality item very happy and will be purchasing all my milling bits from here from now on
Excellent quality product. Lasts longer than other alternatives & is available locally!
These End Mills are great value!
Thank you so much Adam, these drill bits are prefect and last well! we will be ordering again! :)
Whilst I only use this bit for HIPS plastic it provides excellent results for this application
excellent bit cut my aluminum job easily
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.
Excellant service in speedy turnaround
Have done quite a bit of cutting with this bit in brass and it performs nicely. Adam's Bits is a reliable source for end mills.
