2, 3 & 4 Flute UP CUT Carbide End Mill

1/8-1/8-SP-2F-22 [C1]

A spiral fluted up cutter sports a number of cutting edges or “teeth” which means that for every rotation of the bit, that number of edges will be cutting your material. These bits are like a traditional drill bit in which the spirals direct chips up. A benefit of a spiral fluted up cut is that you can drive your bit faster in feed than a single flute. For example, with 2 flute you are able to go 2x faster than a 1 flute, 3 flutes 3x and 4 flute 4x. These cutters are primed for high efficiency cutting on woods but do leave a slight burr on the top of your material and a clean finish on the bottom side.

Suitable for

  • Plastics (ABS, acrylic, HPDE etc.) - 3 & 4 flute not suitable
  • Wood (MDF, hardwood)
  • Wood (Ply & softwoods)

Adam’s Tips

Up cuts have a tendency to pull up the material you are cutting. Ensure that the you are using suitable hold down methods such as double sided tape, masking tape + super glue or clamps over a small area. Also watch out for cut parts popping up if you are using a dust boot.

    I used this bit recently for the first time to carve some intricate flat bottom grooves in timber and found it work well and left a nice smooth finish. Another quality Adam’ Bits product and certainly recommend.

    Tough stuff!

    Posted by Daniel Gamble on 3rd Dec 2019

    I'm still fairly new to the CNC universe and was playing with aluminium for the first time. Not only did this end mill cut clean but it did so after it had survived more than a few poor decisions on my part and before I had my speeds, feeds and plunge rates dialled in properly.

    I love this bit. It cuts beautifully, including through one of my aluminium clamps. I think I'm a convert to four flutes
