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

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!

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!

Only 1 cut so far but almost no cleanup after first cut

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

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.

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.

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.

Works perfectly on plastic routing
