The ESCO Tool Company was founded in 1954 and developed the first portable end prep tool for the Trident Nuclear Submarine program. Always solutions-oriented, ESCO developed the first narrow body I.D. clamping tool in the 1970s to satisfy the needs of the boiler industry. We design and build robust gear drives and housings, select the best components available in the world, incorporate self-centering draw rod assemblies that rigidly mount to the tube or pipe I.D., and feature the EscoLockTM wedge-style blade lock system with TiN (titanium nitride) coated cutter blades that direct heat away from the tube or pipe surface. Providing torque-free operation, these tools pull a continuous thick chip without cutting fluids.
