HSS-XE Core Drill Nitto/Uni Shaft Usable Length 30 mm

Product details:
Core drill bit made of HSS-XE special steel + DURABLUE coated.
In hard use, only in the rarest cases can be taken into account optimal speeds and cooling. The Karnasch Durablue coating makes the core drill significantly more resistant. Ultimately, this significantly increases the life of the drill.

Features:
Shaft diameter d2: 19 mm / (3/4 inch)
Drill diameter d1: selectable from 12 - 60 mm.
Nitto/universal shaft.

Other sizes, quantities or shaft types on request!

Made of high-alloy HSS-XE special steel. For extreme hardness at the tips [up to 68HRC] Thus, high wear resistance and service life.
Our highest quality core drill bits get the unique and patented DURABLUE coating.
Extreme surface hardness and smoothness result in extreme service life, even under inoptimal working conditions such as "overhead working", dry drilling, etc.
Few manufacturers are able to manufacture hardened core drill bits in steps.
For us, this is "standard". As a result, we achieve extremely hard tooth tips [68 HRC] yet a flexible core drill.
Seven different cutting geometries, optimised depending on the diameter and cutting depth of the core drill, resulting in the highest cutting performance.
Completely sanded from the full material. This fine grinding increases the cutting performance while reducing friction.
For a longer service life.

Use:
The HSS-XE drill bit with the best value for money for all steels up to 1100 N strength, as well as stainless steel and copper, brass, aluminium, GRP, CFRP, grey cast iron.
