High Gloss SBFR50 200R020-D6 Tungsten Steel Carbide Parts Centering Machine Small Hole Boring Tool for Stainless Steel/Steel
This SBFR50 200R020‑D6 small‑hole boring tool is specially built for Swiss‑type CNC lathes. Made of solid tungsten carbide with high‑aluminum nano‑coating, it delivers great hardness for machining steel and stainless steel materials up to HRC50, ensuring solid basic cutting performance.
Precision‑ground cutting edge supports high‑gloss finishing for tiny inner holes. Optimized chip‑breaking geometry helps smooth chip removal inside narrow bores. It effectively reduces built‑up edge and tool wear, producing smooth mirror‑like surface finish on workpieces.
Compact and rigid tool body fits limited inner‑hole machining space perfectly. It maintains stable precision during long‑time continuous processing, lowers tool replacement frequency, saves production cost and improves overall working efficiency for small‑part mass manufacturing.
