Our Radial Relief Boring Bars, available in both coated and uncoated options, are designed for precision and durability.
Made with premium submicron grade carbide, they offer exceptional strength and wear resistance.
The radial relieved cutting clearance ensures maximum cutting strength, while the polished flute face optimizes chip flow for superior performance.
The AlTiN+ coating extends tool life and improves surface finishes, enabling higher cutting speeds for increased productivity.
Ideal for a wide range of applications, these boring bars deliver the reliability, precision, and efficiency required for demanding machining tasks.
