A problem solver for holes below 24 mm (0.945 inch) diameter. This complementary tool is optimized for unstable conditions, providing increased process security and stability for smaller hole diameters.
Excellent choice for unstable conditions
Robust drill-body concept and insert design
Good choice for non-rotating applications
Plunge milling is an effective method for roughing out cavities. It makes a deeper hole or cavity through repeated axial cuts. Coromant U drill can be used in broad machining conditions.
High tool body strength enables demanding plunge drilling operations
Power efficient, productive solution with high metal removal rate
T-Max U stack drill is optimized for stack drilling–a method used for drilling large numbers of holes through thin plates. When the drill breaks through a stacked plate, it creates a minimal disc that is evacuated along the chip channel.
Productive stack drilling
Efficient chip evacuation
Indexable insert drill
