Thin-film diamond tools CVD diamond coated tools, using sp³'s patented "DIAbide" process. Tools include: endmills, profiling endmills, premium moldmills, drills, indexable inserts, profiling inserts, grooving, cut-off and threading inserts. sp3 also offers a custom coating service for customer-furnished cutting tools, wear parts, seals, and other carbide items.

Thick-film diamond tools sp³'s new “TFd” indexable inserts feature a cutting surface of pure diamond with no binder. TFd inserts provide a wear life 2 to 3 times that of PCD, and maintain edge sharpness longer. Absence of binder avoids chemical interaction with coolant or workpiece material.

Polycrystalline diamond tools PCD inserts, PCD and PCBN brazed cartridges, screw-on inserted cartridges. Also custom tools and a comprehensive tool refurbishing service.
