TRIANGLE TOOL KEY MILESTONES
Triangle Tool was established in 1968 by Roy Luther, whose vision laid the foundation for the company’s enduring reputation in precision toolmaking.
In 1988, having outgrown its original building, Triangle moved to its present home on the northwest side of Milwaukee, where it continues to operate today.
Building on decades of growth and stability, Triangle entered a new chapter in June 2021 when it was acquired by TPC.
