Multi-cutter deep hole drilling with internal chip evacuation. Coolant flows between tube and hole wall; chips exit through the hollow tube. Diameters 12–500+ mm.
Single-lip precision drilling with internal coolant. Chips evacuate via external V-groove. Best surface finish, tightest tolerances. Diameters 0.5–50 mm.
Dual-tube system using venturi suction for chip removal. No pressure head needed; retrofittable on conventional CNC. Diameters 18–200 mm.
Tool that guides itself via guide pads bearing against the bore wall, not solely by the machine spindle. Creates low straightness deviation.
Combined finishing process — carbide blades create a round bore, then rollers cold-work to mirror finish (Ra 0.05–0.4 µm). Replaces honing for hydraulic cylinders.
