Achieve maximum rigidity and precise center height positioning during heavy external turning, facing, and profiling operations with industrial-grade Turning Toolholders (CNC lathe block holders). Engineered with precision-milled mounting faces and robust clamping plates, these heavy-duty tool blocks securely clamp standard square-shank turning tools. Outfitted with high-tensile locking bolts and integrated internal coolant nozzle ports, they deliver rigid tool support and targeted fluid delivery directly to the cutting insert, eliminating deflection and extending tool life across demanding turning applications.
