GUHRING Carbide Coating Drill Carbide Small Diameter Drill Alumina Coat Blade Diameter 1.71mm 3899 001.710 GUHRING

[Features]
By using ultra-fine particles (DK460UF), we have achieved stable blade strength, rigidity, breakage resistance, and a high-quality blade shape with little variation.
The alumina coating ensures a long life and stable machining.
The shank diameter is standardized to 3 mm for ease of use.
Ideal for ultra-small diameter metal processing and high-precision small diameter drilling for electronic devices, etc.

[Applications]
Workpiece materials: general structural steel, carbon steel, alloy steel, stainless steel, cast iron.
