When cutting soft metals like aluminium & brass, there is nothing easier to use and more suitable than a high grade 1 flute up cut. An 1 flute has the best chip ejection and heat dissipation which avoids jamming due to the gummy nature of soft materials. An 1 flute also has the capability to operate effectively with widely varied feeds and speeds as compared to 2 & 3 flute when slotting. For peripheral cutting, a 2 or 3 flute for soft metals is ideal for the side & bottom finish.
- Soft Metals (Aluminium & Brass)
- Plastics (ABS, acrylic, HPDE etc)
- Aluminium Composite Materials
You will get a different finish on the side of your material depending if you use a climb or conventional cut. Do some test cuts and check which side comes out the best and adjust your toolpath accordingly. These bits are great on plastics as they are really tough but do not have a sharp edge. You will be able to run these bits faster on plastic compared to a 1 flute (for plastics) bit but depending on the finish you require, might only be suitable for cutting all the way through.
