Radius Boring Bars

Enhance your machining capabilities with our high-performance Radius Boring Bars, available in both coated and uncoated options. The AlTiN+ coating extends tool life and improves wear resistance, while the polished flute face ensures optimum performance for smooth chip evacuation. The strategically designed corner radius provides superior strength, better surface finishes, and improved cutting efficiency. B050 and B060 tools require a 3º side clearance for optimal operation. Perfect for high-speed, precision machining, these tools offer exceptional durability, consistent results, and reliable performance across a variety of materials. Whether you need extended tool life or superior surface finishes, our radius boring bars deliver the quality and performance needed for demanding tasks.
