Which carbide insert to get

[grz5]

I got a hold of some SS stock and I turned and milled it to size. Now I'm trying to decide which insert to get.

My options are:

For Titan Spiral Shear Heads -- 15mm x 15mm x 2.5mm - 4-edge - 8 Radius

AND


For "Byrd" Shelix ® Journal (Helical) Heads -- 15mm x 15mm x 2.5mm - 4-edge - Radius Faces

Basically the 2 options that the woodpen pro have.

Is there a difference between the two inserts or does it not matter?

Here's a link to the site.

Carbide Insert Knives - Global Tooling


Please let me know if one is better than the other.

Thanks,
Garrett

The one on the bottom of your post is the ones that I use. They have BT on them.

I use the Byrd inserts from Global as noted above in my Woodchuck. They work fine.
