Hi, the helix cutters are listed as drills. Do you want to drill or rout? G.
I need to mill/rout however I have noticed that all their bits are called drills if there mills or drills :S
The helix cutters need to have a sharpened edges at the bottom and are usually referred to as end mills. If you want to try one, PM me your address and I will send you one. G.
I've used these for cutting PCBs to size. Gave a very clean finish. However I've been told that carbon fibre leaves luch more fine abrasive dust than glass fibre. In that case the tool apparently wear very fast and a burr type is better.

Slightly on topic, where can you buy the sheet FR4 or similar fibreglass?
