10% KEUE CNC SBFR MNR60200R020-D6 Tungsten Steel Small Bore Boring Tool Carbide Centering Machine 0.001mm Precision 3-Year
This SBFR small‑aperture boring tool adopts silicon‑containing nano‑coating on solid carbide substrate. It delivers outstanding heat resistance and wear resistance, perfectly processing steel and stainless steel within HRC50 hardness range. It effectively reduces tool wear and builds‑up edge during continuous finishing cutting for stable machining results.
Optimized 15° & 5° cutting‑edge geometry is specially designed for Swiss automatic lathe finishing. Smooth chip flute ensures smooth chip evacuation in tiny inner holes. It minimizes vibration in small‑diameter boring work, producing fine inner‑wall surface finish and keeping consistent dimensional accuracy for precision parts.
Model SBFR MNR60200R020‑D6 is dedicated to micro‑hole fine boring tasks. Rigid tungsten steel shank improves clamping stability and avoids chattering. Ideal for high‑volume precision production, it lowers tool‑changing frequency and raises overall processing efficiency for small‑size component mass production.
