Helical Boring Bars
Achieve superior machining results with our helical boring bars, designed for both mill and lathe applications. The "A" minimum bore diameter ensures precise hole sizing when rotated on the centerline, delivering accurate and consistent performance. Made from premium submicron grade carbide, these tools offer exceptional durability and strength. Available in uncoated and coated versions, the AlTiN+ coating enhances wear resistance while providing a smoother surface finish for high-quality results. Upgrade your machining capabilities with helical boring bars engineered for precision and versatility.
