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.

    1 Flute for Acrylic

    Posted by Waqas Qureshi on 6th Jan 2021

    Can't say much about the bit itself yet as (due to my own stupidity) I keep breaking them. Sometimes I drill it right down into wasteboard screws, sometimes simply trying to set the Z axis and moving the router way too much). When I manage to get it right, it does what it is supposed to do, however I am still trying to find out the right settings for Acrylic. But, my experience so far has been more than excellent with Adam. Both in terms of speedy delivery, quality of the products and most importantly for me, being extra helpful, answering all my newbie questions and guiding me along. I highly recommend Adam's bits as well as the CNC machines (BlueCarve).

    I know it's my first end mill, but it's great. Tested on MDF and it gives sharp, clean cuts all the way through.

    OK on Aluminium

    Posted by Don on 7th Feb 2020

    Good value. Arrived fast. Works fine on Aluminium with no lube using shallow cuts and multiple passes. 2mm bit chatters if deeper cuts attempted. Probably better with lube, but I didn't want the mess on my hobby CNC Router.

    I have used this end mill on MDF with a fairly high feed rate, the cutter performed well leaving a very clean cut. Highly recommend.

    Down cut done the job with out excess chipping

    Job Aboriginal Art, engraving 3mm x3mm deep line and concentric circles with a space of 3mm between cut with cross hatching, it left the cross hatching areas cutting clean, on iron bark, slow but doing the job Thanks Michael
