TE-H 11/8 in. Hex Self-Sharpening Chisels offer a polygon design and inductive hardening process so the tool stays sharper longer. A permanently sharp chisel blade makes normal resharpening and rehardening associated with standard chisels unnecessary, allowing users a high level of chiseling performance. The chisel increases efficiency and removal rate by up to 30% compared with an unsharpened chisel. The polygon design helps prevent it from jamming in the base material.
