We are running down our stock of uncoated 1 flute aluminium cutters and eventually will only be stocking DLC coated cutters. DLC coated cutters cut faster, longer and cleaner than uncoated and can be found >>here<< If we no longer have a size in uncoated, we will be shipping the DLC version.

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.

Perfect cutting in Brass

Posted by Jorden Baker on 26th Apr 2021

I had been struggling for so long to try and cut small brass gears and pinions. Not being able to afford a lathe, these 1 Flute cutters have been amazing. They have opened up all sorts of new possibilities for me. Great quality at a great price.

Best Bang for Buck Bits.

Posted by Theo Nestora on 25th Mar 2021

I've been using Adams bits exclusively for the past 9 months. Best Bang for Buck by far. Dimensionally stable bits with zero run out. Highly recommended.

Router End Mill

Posted by Philip on 22nd Feb 2021

I machine aluminium using a CNC router and was paying upwards of $60 for each solid carbide, single flute end mill. Adam's bits do the same job for a quarter of the price and have saved me a lot of money over the past four years.

Geat Quality

Posted by Daniel Williams on 18th Dec 2020

I've been cutting with them for a number of weeks now and have had no issues, broke a few bits, but that was due to machine issues

Single flute up cut bit for Aluminium

Posted by Murray Macpherson on 28th Oct 2020

I tried some single flute bits from Adam's bits on polycarbonate which is my preferred plastic for CNC work. Very impressed with how clean the result was. These single flute bits will be my go to bits from now on!

1 flute upcut for aluminium

Posted by Peter Crowder on 26th Aug 2020

Thanks Adam, We are new to the world of CNCing and cutting our aluminium plate with clean cuts and hole was a horrible experience before we found Adams bits.
