Bevel the bowden tube ends

I use a very convenient tool to deburr/countersink/bevel the bowden tube ends. I found it by chance and it is very cheap. Now I use it everywhere (it also will deal with aluminium by the way).

There are two reasons to use it on bowden tube ends in my opinion :
  • it reduces friction of the filament on the tube square edges
  • it makes the tube softer so that it can be applied with progressive force against the PEEK for example, for a better seal
Before buying the tool I used my biggest drills, but it was much harder to do a proper job.

To remove the hairy results afterwards, quickly rotate a big philips screwdriver in the bevel


  1. Sorry I can't help... I found it by chance in a hardware shop, among a pile of unsorted cheap stuff. I paid a few euros if I remember. I can't help either with the name as I don't even know it in French :s

  2. Sold as a "3 in 1 Countersink Set" at Jaycar in Australia...

  3. Found again at 5.55€ in Castorama, France.

    Full ref is: Wolcraft 4315, e.g http://www.wolfcraft.com/en/products/p/hand_countersinks/1_hand_countersink/s/p/index.html

  5. Thanks Nic. I hope I'll get the chance to visit the surroundings of any Australian city at some time ;)
