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.

4 Flute 6 mm Upcut Bit
It's a great bit with plenty of cutting power for roughing. Since I've moved from two flutes to four flutes, I've had far fewer problems with the bit biting in and wandering or causing stoppages. I only use it for wood (pine and oak), so I don't have any coolant. Even on the pine, the bit heats up significantly, causing bit discolouration and accelerating the dulling (~20 hours of use, 1.6 mm stepdown). It's still really great for the price.

Extra long endmills
The extra long endmills look great, but I haven't used them yet, but I have bought quite a few other CNC router bits from Adam and they all have been very good quality and perform very well.

Bought a few of these at once because I've had them break too easily but so far these are working great! Delivery was quick too so couldn't be happier.
