SUPERMILL, originally founded as Primary Cutter Grinding in 1990 in Berlin, Connecticut, started as a regrind and recondition facility for the aerospace, defense, and firearm manufacturing industries.
Recognizing a market need, SUPERMILL introduced high-performance solid carbide endmills and has since built a nationwide network of distributors and end-users.

Joining the IMC Group (International Metalworking Companies) has provided enhanced support and guidance, advancing SUPERMILL’s manufacturing technologies and maintaining top-tier customer service and technical support.
This partnership marks a significant milestone, accelerating SUPERMILL’s growth in the dynamic solid carbide endmill market.
SUPERMILL’s product lines now feature Ultra performance endmills with
specialized geometries and in-house PVD tool coatings for specific applications and maximum productivity.
