55mm HSS-XE Annular Cutters, Nitto/Uni Shank, Gold Line

Annular cutter made of HSS-XE special steel + GOLD-TECH surface treatment.

Karnasch Gold-Line annular cutters are the most commonly used non-coated HSS-XE annular cutter.

Made of high-alloyed HSS-XE special steel. For extreme hardness at the tip of the tooth [up to 68 HRC]. This guarantees a high wear resistance and lifetime.

GOLD-TECH surface treatment: the special treatment for higher lifetimes.

Completely made FULLY GROUND. This refining rises the cutting ability with reducing friction at the same time. For an exceeded lifetime.

Only few manufacturers are capable of producing step-hardened annular cutter.
For Karnasch this is standard. Only this makes us produce extremely hard tooth tips [68 HRC] and yet a flexible annular cutter.

Seven different cutting geometries optimally adapted to the different diameter and cutting depths leads to high performance cutting results.

USAGE:

By special surface treatment GOLD-TECH + FULLY GROUND + special steel HSS-XE ideal for drilling in steel up to 900 N and even suitable for stainless steels.
