Screw-in head with internal cooling EXN02R High Feed | Small diameters | Ø8-Ø17 - LNMU0202 inserts

Screw-in head with internal coolant EXN02R High Feed | Small diameters | Ø8-Ø17 - LNMU0202 inserts

EXN02R head - a small-diameter solution for fast feed on hardened materials.

Made of 42CrMo steel with internal coolant, ensures high material removal rate.

Thanks to a maximum cutting depth of 0.5 mm and 4-fold LNMU02 inserts, it effectively replaces traditional solutions.
