Ratchet wrench 1/2" Adler 72-tooth Cr-V model 3552.2

Adler 1/2" ratchet wrench model 3552.2 is a hand tool designed for mechanical and automotive work. Constructed from chrome-vanadium (Cr-V) steel, the ratchet features a 72-tooth mechanism that enables fine-tooth indexing for precise tightening and loosening of fasteners in confined or hard-to-reach spaces. The tool accepts standard 1/2" drive sockets and is intended for routine maintenance, assembly and repair tasks.

Advantages

The 72-tooth mechanism reduces swing arc requirements, allowing incremental engagement and accurate torque application in limited-clearance areas. Chrome-vanadium construction provides a balance of strength and wear resistance suitable for repeated hand use. The 1/2" drive size is compatible with a wide range of sockets and accessories, making the wrench adaptable for general workshop and automotive tasks.

Suitable for

• Automotive repair and maintenance
• Mechanical assembly and disassembly
• Routine workshop and service tasks
• Working in confined or tight-access locations

Key specifications

• Drive size: 1/2" (square drive compatible with 1/2" sockets)
• Tooth count: 72-tooth fine-ratio mechanism for small swing angles
• Material: chrome-vanadium (Cr-V) steel body
• Function: reversible ratchet mechanism for tightening and loosening
• Typical use: manual hand tool for sockets and related accessories

How to use

Select an appropriately sized 1/2" socket and attach it securely to the square drive. Set the ratchet direction to either tightening or loosening using the reversible selector. Operate the wrench with steady hand force, using short swing arcs where clearance is limited to take advantage of the 72-tooth indexing. Periodically inspect the tool for wear and ensure sockets are fully seated before applying higher torque.

Usage recommendations

For prolonged tool life, avoid using the ratchet as a hammer or prying device, and do not extend the handle with cheater bars. Clean and lightly lubricate the mechanism occasionally to maintain smooth engagement, and store the wrench in a dry environment to reduce corrosion.
