Crimping Tool AWTools AW31570 — mechanical cable crimper for copper/aluminium terminals 6–50 mm²

The AWTools AW31570 is a mechanical cable crimper designed for reliable crimping of copper and aluminium lugs and terminals sized 6–50 mm². The tool uses a manual ratchet and mechanical leverage to apply consistent pressure across the crimp profile, producing secure electrical and mechanical connections for power distribution, control panels and grounding systems. Its range covers common conductor cross-sections used in residential, commercial and light industrial installations.

Advantages

The crimper delivers repeatable crimps through a robust mechanical mechanism and ratchet release that prevents incomplete crimps. It supports both copper and aluminium terminals and covers a wide 6–50 mm² range, reducing the need for multiple tools. The construction emphasizes durability and user control, with long handles to increase leverage and a compact head for access in confined spaces.

Suitable for

• Electricians performing terminations on power and distribution circuits
• Installation and maintenance of control panels and switchgear
• Grounding and earthing conductor connections
• Field service work where a manual, portable crimper is required

When it may not be suitable

The AWTools AW31570 is a manual mechanical tool and may not be suitable where very high-volume production or automated crimping is required; in such cases hydraulic or bench-top automatic crimpers are typically preferred. It also may not be ideal for very confined spaces where handle length prevents access or for terminal types and profiles outside the specified 6–50 mm² range.

Key specifications

• Supported conductor cross-section: 6–50 mm²
• Material compatibility: copper and aluminium terminals
• Operation type: manual mechanical crimper with ratchet mechanism
• Application: cable lugs and terminals for power distribution and grounding

How to use

Select the correct die or position on the crimp head for the terminal size, insert the prepared cable and terminal so the conductor is fully seated, then operate the handles until the ratchet completes the crimp cycle. Release the ratchet and remove the crimped connector. Ensure the conductor insulation is trimmed to the correct length and the terminal is appropriate for the conductor material (copper or aluminium) before crimping. Inspect the crimp visually and, where required, with a pull test or electrical continuity check to confirm a secure connection.

What to consider before purchase

• Confirm the tool's 6–50 mm² range matches the conductor sizes you will be terminating
• Verify compatibility with copper and aluminium terminals you intend to use
• Consider whether a manual crimper meets your throughput needs versus hydraulic or powered alternatives
• Check access requirements where the tool will be used to ensure handle length and head size are suitable

Usage recommendations

Use appropriate personal protective equipment and follow local electrical safety practices. For reliable results, match terminal type and size to the conductor, perform a visual inspection after crimping, and conduct a mechanical or electrical check when required by standards or site procedures.
