I am amazed at how well these bits cut. We recently started cutting thin aluminum sheets on our CNC router (0.025 inches thick). We were having issues with our expensive, name-brand uncoated carbide bits loading up with aluminum and destroying the cut edges of the parts. I did a bit of research and came across mention of TAC coated bits being the best for aluminum. I decided to order one of Spetool's TAC coated 1/4 inch O flute upcut bits to test out. This bit has blown me away. I have never used a bit before that goes through aluminum so easily and cleanly. I have cut hundreds of feet of .025" anodized aluminum with the same bit, as well as some 3/4" MDF. It is still razor sharp with no visible wear on the edge or the coating. I am cutting it on a vacuum table, with no coolant and no air blast. I can grab the bit immediately after cutting up a sheet and the bit is cool to the touch. The large o-shaped flute never clogs and the surface of the bit is so smooth and slippery that not even painter's tape will stick to it when I run through a strip of it.I am running the 1/4 inch bit at 15,000 RPM and feeding at 60 inches per minute, step cutting parts out in two equal passes and have had no issues whatsoever. I'm sure it can go faster, but I did not want to push it on a project close to deadline. Oh, and it's about a third of the price of the bits we normally buy. Buy this bit. You will be happy that you did.

Bought this for a spare just to have on hand. The first one is still cutting well.

Very high quality sharp bits that cut super smooth. Cut 1-1/2" thick hard maple solid wood in 1/8" CNC step-downs and got a mirror finish!

I have had good luck with the quality of SpeTools endmills. I mainly machine acrylic, resin, and micarta. Works great for the application. Buyer beware of the tool size as they are not true, they are advertised as 1/16" or 1.6mm endmills, the pack i received measured out to 1.25mm so make sure you are adjusting cutter comp for the size and measure each endmill individually.

This bit is the only one, besides the 1/4 inch version that will consistently cut through aluminum like butter. It leaves perfect machining marks as well, and doesn’t clog. I’ve found these cut smoother on plastics and wood as well. I’m a single flute guy now.

Purchased to make edge lit acrylic signs. Cuts well and leaves a nice finish on the edge walls. There are better bits, but for the price these will do well for my use case (18000 rpm. 100 ipm, xy feed, 30 ipm. plunge.Quick delivery on Amazon (got to love prime).

Endmill arrived pretty quick and I have it mounted in my router. I like that spetool now has tool libraries to use in fusion 360. Makes it ALOT easier to make stuff.

These SpeTool bits are superb. They are cut beautifully. Durability is hard to determine quickly, but I'm very happy. There are speeds and feeds available on their website.For the novice CNC'er, I can't think of a better tool brand to invest in.

Holy smokes these things are nice. I've never used a cutter that just flows through aluminum like its foam. Highly highly recommended!!

I needed to rout a channel in hardwood for the wire of a cheese slicer that I was making. In the past I used a table saw but I no longer have one
