The Greenlee Intelli‑PUNCH LS100X11SB4 battery‑hydraulic knockout tool is engineered for fast, accurate hole punching in electrical installation and fabrication work. Its pressure‑sensing auto‑retract technology detects punch completion and retracts automatically to protect tooling and improve cycle efficiency. The compact, ergonomic design allows one‑handed operation, while the rotating head supports punching at virtually any angle. Slug‑Buster punch geometry splits material for easier slug removal, supporting cleaner results and reduced downtime for professional electricians and maintenance crews.
