Small-Diameter Round-Shank Boring Lathe Tools




These are the smallest boring tools we offer. Use them to enlarge existing holes to precise diameters. Made entirely of micrograin carbide, which outperforms C2 and C6 carbide when cutting difficult-to-machine metal, such as stainless steel or titanium. It provides a good finish on most materials. Tools have flats on the shank for quick alignment.
Style 3 tools have an extra long shank for boring in deep holes.
