The precision NBH2084 model boasts an astonishing failure: 20-84mm compact casing with 360° indexable insert carrier that makes multi-edge cutting for superior effectiveness more convenient. Along with strong pumpping pressure of 70 bar supplying the internal coolant channels that flush deep berry effeciently, the spindle’s stringent runout of 0.003mm guarantees perfect hole straightness. It surpasses swiss precision standards making it suited medical, aerospace and critical swiss components.

Frequently Asked Questions

What precision can boring heads achieve?

They achieve hole tolerances of ±0.005mm and surface finishes Ra≤1.6μm via fine-thread adjustment (0.5mm pitch) and carbide-tipped inserts for aerospace engine blocks and hydraulic valves.
They accommodate hole diameters from 5mm to 500mm, with adjustable cutting edges for both manual and CNC milling/boring machines (BT, HSK interfaces).
