SpeTool Single Flute (O Flute) Spiral End Mill Aluminum Cutter Carbide Router 1 inch Cutting Length with 1/4Inch Shank for Aluminum Acrylic PVC MDF Plastic

This cutter has been great for me! I was able to do 14mm depth of cut, single pass, at 1500mm/min with no issues in HDPE. Aluminum I was able to cut 6mm depth of cut, single pass, at 400mm/min. I did get some chatter there, but a finish pass woulda fixed that. If I run a 2nd pass at 0.1mm depth, the finish is very reflective on aluminum, not using air-blast or coolant. Tool cutting ability all depends on how rigid your machine is. This cutter has no problems bogging down my dewalt router. Need a much more powerful spindle to truly push this cutter. Very impressed!

I used this to cut slots in an aluminum extrusion. It worked much better than Id expected.

Works perfectly on plastic routing

I really hate having to say anything negative about SpeTool as I have used plenty of their products in the past and have been generally very satisfied, but this thing was a very fast waste of money. Decided to test it out in a thin piece of pine at low feeds and shallow doc, and the end mill snapped within the first 30 seconds! Most likely will not buy again!

I run lots of different bits and this brand is one I can for the most part count on as being a decent bit. Not the best but not the worst brand. I have had pretty good luck with the brand but have had a few that didn’t last very long or just not up for the job. They are not super expensive but not cheap ether. With so many choices I can usually count on them. If i am doing a big job or something that is really precise i don’t use them I will use a brand I trust a bit more. Not saying this is a bad brand.

Looks like a quality bit, but cut quality is terrible. Not sure if I just got a bad one, but it’s useless unless you want to sand forever.

Carve like butter. This bit was surprisingly great on the xcarve. I had no issues.

Works with aluminum good

I ran this faster and deeper than I thought I would be able to. Ramp into your material, and use a nice cutting/cooling fluid, and go for it. Nice bit, really.
