Highly reliable, accurate machining

• Optimal balance of the central insert and peripheral insert dramatically suppresses the vibration that occurs when the drill engages and penetrates the material

Supports a wide range of work materials and applications

• Indexable inserts come with 3 types of chip breaker to accommodate a wide range of work materials, from general steel to difficult-to-machine materials, which often present problems related to chip removal
• One tool handles everything from normal drilling to hole expansion, counter boring, external machining, and more

Long tool life

• 4-cornered insert for superior economic efficiency
• New material and new ultra-thin multi-layered coating for longer tool life
