Professional Ratchet for Mechanics

Klein Tools 65820 is a 1/2-inch drive hand ratchet forged from alloy steel with a durable chrome-plated finish. The 10-inch length provides solid leverage for automotive and maintenance tasks. A 72-tooth round head and classic dial switch allow quick direction changes. Corrosion-resistant construction supports long service life in professional environments.

Suited for Daily Workshop Use

This ratchet fits technicians who need a reliable 1/2-inch drive tool for general fastener work. The forged alloy steel body withstands repeated torque cycles. Buyers who require an insulated handle for electrical safety should look elsewhere. Users needing a longer handle for extra reach or a different drive size will need another tool.

The 72 geared teeth inside the round head deliver fine incremental engagement for efficient tightening and loosening. Male square 1/2-inch drive accepts standard impact and chrome sockets. Overall length is 10-1/2 inches (267 mm). California Proposition 65 warnings apply for cancer and reproductive harm.
