Aug 27, 2014· One strategy that we’ve found to be effective for milling threaded holes in acrylic consists of a one-two punch helix drilling first and thread milling second. As an example, we recently helix drilled an acrylic part with a 2mm single-flute end mill at 20,000 RPM and a feed rate of 10 inches per minute with 1.0mm Z infeed.
Acrylic End Mill. In addition to our proven single-flute end mills with polished flutes, DATRON now offers a wide range of form end mills. These polished milling tools allow achieving highly transparent milling results for the most diverse applications. Just try them out!
These carbide-tipped end mills provide a sharper, harder cutting edge and better wear resistance than high-speed steel without the brittleness of solid carbide. Their teeth are angled on both sides so you can make top and bottom chamfer cuts without having to flip the workpiece.
You will never get the best results using wood bits to cut acrylic as cutting and chip removal is key. We recommend using a bit that is specifically designed for cutting acrylic. We found that we get the best results using an “O-Flute” end mill. If you read online, many posts will have you use the largest diameter end mill that you can.
Compression end mills combine the best of both worlds and produce a smooth surface on both ends of the workpiece when cutting. Starter Pack End Mills. So what type of end mills do you require for general milling applications? For hardwoods, plywood and aluminium: High quality 2-flute (slot drills) up-cut and down-cut end mills.
Plastic and Wood Cutting End Mills for Improved Finish, Prevent Workpiece Lifting Upcut End Mills & Down Cut End Mills for Wood/Plastic. Upcut End Mills for Cutting Plastic and Wood provide maximum chip clearance for chip evacuation to prevent chips from sticking or packing in the flutes.
Typically with Acrylic, the wider-diameter the mill, the glassier the finish. I took a 2-flute 1/2 inch bit through acrylic and it came out looking magical. I recommend getting the Onsrud Catalog (honestly love their bits too, personally). Towards the bottom, you will see charts for various types of material.
Ideal feedrate for cutting Acrylic is typically 75-300 IPM, depending on the size of your bit. For example, an 1/8" bit work better on the low end (75-100) while a 1/2" bit would work well at 200-300. This is for the sake of the bit as much as the material. Again, the larger the bit the better.
May 16, 2015· Acrylic is hard to cut! I’ve mainly been working on clear acrylic. So far, I’ve had the best results using the straight 2 flute bit (the one sold here on Inventables and included in my End Mill Starter set) at a feed rate of 40in/min, 0.02" deep passes.
A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing them
Plastic and Wood Cutting End Mills for Improved Finish, Prevent Workpiece Lifting Upcut End Mills & Down Cut End Mills for Wood/Plastic. Upcut End Mills for Cutting Plastic and Wood provide maximum chip clearance for chip evacuation to prevent chips from sticking or packing in the flutes.
Feb 03, 2016· “We were having trouble finding a plastic-specific cutter with enough flute length to cut this 2" thick acrylic, and HarveyTool was the only source we could find that even made one large enough

Oct 16, 2018· This is the strongest end mill style. A fully rounded cutting edge has no corner, removing the mostly likely failure point from the tool, contrary to a sharp edge on a square profile end mill. An end mill profile is often chosen by part requirements, such as square corners within a pocket, requiring a square end mill.
Ideal feedrate for cutting Acrylic is typically 75-300 IPM, depending on the size of your bit. For example, an 1/8" bit work better on the low end (75-100) while a 1/2" bit would work well at 200-300. This is for the sake of the bit as much as the material. Again, the larger the bit the better.
After trying a large single flute upcut on acrylic I knew I had to get a smaller plastics upcut for the acrylic letters we produce. It did not disappoint at all, producing nice chips, not melting or welding the acrylic The smaller size meant the table had a better chance at keeping the small shapes held down and the edge finish is perfectly
May 31, 2014· If its a run of the mill "plastic" not a reinforced thing (I hear that PEEK stuff is a mother.. ) Moderate speed, heavy ish feed. If it melts back down the speed, if its then happy, up the feed. I have yet to break a chip in "plastic", keep that in mind. Feed, HARD, I drilled some UHMW a
