Sonic Tools LP builds solid carbide end mills and custom carbide tooling in Ashland, Virginia. Sonic prides it's engineering solutions for solving problems around the constraints of the job, rather than being adapted from what already exists. We're trusted when the geometry doesn't exist in any catalog, or the tolerance a previous supplier said couldn't be met still needs to be, or when worn tools need end mill reconditioning to the same spec as new tooling. We solve the problems that others can't. Standard catalog and fully custom, on 5-axis CNC grinding machines, with engineering and production under the same roof. Aerospace, firearms, biomedical, power generation and more. Manufacturing tooling solutions in the USA since 2004
