KEUE CNC Precision Tungsten Steel Internal Boring Tool MQR 4R0.2 L15 for Small Bore Machining 2.5-8mm Diameter
This MQR solid carbide small‑bore turning tool is built from high‑grade integral tungsten carbide, available in right‑hand MQR and left‑hand MQL reverse‑cut versions. Its special 47‑degree tip angle is optimized for profiling, boring and chamfering on Swiss‑type CNC automatic lathes.
Precision‑ground cutting edges deliver stable cutting performance for steel and stainless‑steel workpieces. The optimized geometric angle reduces cutting resistance, guarantees precise profiling contours, reliable dimensional accuracy and excellent inner‑hole surface finish during continuous machining.
High‑rigidity one‑piece carbide shank improves anti‑vibration performance and extends tool service life. It meets diverse small‑hole profiling demands, lowers tool‑changing frequency and tooling costs, and effectively boosts batch‑processing productivity for precision parts.
