New Carbide3D coated cutter

Are the new coated cutters ; #102Z .125" Zrn Coated Flat Cutter ; conductive ? For those who probe tool length using alligator clip on tool. Googled ZrN cutters with no mention of conductivity. Thanks

Yes they are conductive. I have been testing them for a few months, and probe with them all the time.


Ah Ah! Your secrets are slowly being revealed.

Thank you for reply and your efforts Richard

PS These new cutters are amazing; nothing stickes to them!

I have machines miles in Aluminum without a drop of WD40 (and I’m on the same cutter, it just doesn’t get dull.

Look at me Harley Mini Floorboards for my latest project with this NEW 1/4" End Mill.
