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.

As usual, product was perfect for the job and it arrived almost before I'd had a chance to hit the Order button. REALLY appreciate the Adams Bits catalog which tells you the suitability of each bit on every type of material! A REAL time saver!
