The Groz Center Square is designed to locate the centers of round stocks or parts. The knife edge is made from high-quality spring steel, hardened and precisely ground for durability and reliability. The hardening process makes it resistant to wear and tear, while precise grinding ensures that it maintains its sharpness even after repeated use. With its compact size and easy-to-use design, the Groz Center Square is the perfect tool for machinists who are always on the go, whether they are working on a lathe or at a bench.
