1 Flute UP CUT End Mill (for Aluminium)

(13 reviews) Write a Review
4-4-SP-1F-12-Al [A5]
Suitable Material:
Aluminium / Plastics
Cutter Profile:
1 flute up cut
Suitable Use:

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.

Suitable for

  • Soft Metals (Aluminium & Brass)
  • Plastics (ABS, acrylic, HPDE etc)
  • Aluminium Composite Materials

Adam’s Tips

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.

    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!

    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.

    Purchased 4 & 8mm cutters last week and they cut like a dream on 5083 and 6061 Aluminium on my Multicam router. Would highly recommend.

    I've been doing clearing passes on aluminium for weeks with this now and it's still cutting as if i'd only just started using it.
