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.

Great Upcut

Posted by Dennis on 23rd Jun 2022

Adams Bits don't let you down, every bit I've purchased and used has performed well. Clean sharp cuts, can push them into the hardest timbers and they just cut through, leaving a crisp clean finish.

Spiral Up Cut

Posted by Paul on 1st Jun 2022

Perfect smooth cut everytime even after heavy use. I cut hardwoods predominately and even after significant use have not yet replaced a bit for being dull. Highly recommend!

good product for the price

Posted by James Vagg on 31st May 2022

have not worn one out, the only way i have damaged the end mills is to drop or forget to turn the spindle on.

I bought several sizes including giant 6mmx 62. I use the 22mm heaps for 19mm cuts. They all run well with good clean cutting.
