KEUE CNC Precision 0.01mm Miniature Carbide 3-8mm Diameter 2-Flute Boring Cutter MCR SBCR Inner Hole Fine Chamfering Boring Tool
This SBCR micro boring and chamfering tool is made of solid tungsten carbide alloy. It adopts 45‑degree special geometric structure, with multiple complete size options for small inner hole machining. It works perfectly on CNC lathes and Swiss‑type automatic lathes for inner‑hole chamfering and fine boring.
Precision‑ground cutting edges deliver stable cutting performance for steel and stainless‑steel workpieces. Optimized tool geometry reduces vibration during small‑hole processing, creating clean chamfer surfaces and accurate hole dimensions while maintaining smooth chip removal for consistent finishing results.
High‑rigidity integrated tungsten‑carbide shank supports reliable performance for deep small‑hole chamfering and fine boring. It extends tool service life, lowers frequent tool replacement and machine downtime, helping users cut tooling costs and improve overall mass‑processing productivity.
