Amana ToolSpektra Coated Solid Carbide CNC Carbon Graphite Carbon Fiber Panel Cutting Router Bit Down-Cut, 46008-K, 1/8 D x 1/2 CH x 1/4 Shk x 2 L

Finally found a bit that cuts carbon fiber well. Cutting 5mm without a problem, edges are left better than any other bit I have tried.

Got this for a little hobby milling station I'd been piecing together so I can cut carbon fiber for my rc stuff I was using a dremel and an ez cutoff wheel which works fine until you need to straighten your cuts out which can be a pain to do by hand u really need some kind of mill setup so you can get precise cuts and this bit is great makes short work of anything you through at it it's little to big for doing finer details but I plan on ordering a different Amana bit for that I have to say this is the most expensive bit I've ever bought and it's on the cheaper side of any decent mill bits and you can really see the difference between this one and the same style dremel bit that and it lasts way longer I go through dremel bits like crazy and I mainly cut carbon fiber and carbon fiber / Kevlar but I also do aluminum and steel and several different types of harder plastics and I havnt had to replace it yet.

I've killed many a bit on 3 and 4 and 5mm carbon, this on is going strong and showing no signs so far of giving up!I'll buy another when it does.

Worked great for cutting fiberglass recesses for new thru hull fittings

Perfect end mill for cutting carbon fiber.

did a great job !!
