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

Thanks Adam for the advice prior to me making the choices of bits. this one performs like you said and I am happy with the results. I'll be calling on you again in the near future when I'm ready to increase my arsenal of bits.
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.
Awesome quick service. Items arrived within days. Very impressed.
Very quick delivery. Good product, works well. Very helpful with enquiries.
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.
Thanks again for some very nice cutters... Perfect cut and just in time :) Nicely presented and Great service!
I love this bit. It cuts beautifully, including through one of my aluminium clamps. I think I'm a convert to four flutes
great all around cutter for mdf and marine ply good price and fast delivery times
