A 1 flute down cut end mill is a type of cutting tool that is suitable for cutting a variety of materials, such as aluminium composite material (ACM), plastic, and wood. This type of end mill operates in a similar manner as a 2-flute down cut, but it has a single cutting edge. The design of this end mill forces the chips back down into the material being cut, which can be useful for achieving a clean, precise cut. It's specially designed for the materials that are prone to chip out during cutting. And also, due to its design it's best suited for relatively softer materials with lower cutting forces.
Suitable for
- Plastics (ABS, acrylic, HPDE etc)
- Aluminium Composite Materials
Adam’s Tips
When cutting aluminium composite panel with a CNC machine, the number of passes needed can depend on the rigidity of the machine. Depending on the rigidity of your CNC machine, you may be able to cut the material in one or two passes.
Another consideration when cutting aluminium composite panel is the diameter of the end mill bit. If you find that using a smaller diameter bit (such as 2mm) results in an excessive amount of plastic chips packing back into the slot, you may want to try using a 1-flute up cut end mill for aluminium. This type of end mill forces chips up and away from the material being cut, which can help to reduce the clean-up time. Keep in mind that the up-cut bit will put the chips on top of the material, which may create a mess if not handled properly.

Very happy with the clean top edge on plywood

1 flute down cut.
Have been using this bit to cut 3mm Aluca-panelling and 16mm Melamine Cutting had nice, clean edges with no burrs.

Excellent results in MDF
Have an Openbuilds C-beam DIY mill with a Bosch trim router as a spindle. Runs at 33,000 RPM. When cutting small parts found an uncut bit worked best for roughing and drilling holes. Got a perfect, clean edge when using this down cut bit for finishing.
