iCrimp Self-adjustable Crimping Tool Plier for AWG20-5 - Precise

In this review of the iCrimp Self-adjustable Crimping Tool Plier the bottom line is straightforward: this is a well-made hand crimper for electricians and hobbyists who need consistent, solder-free ferrule terminations. The tool's automatic self-adjustment and full-cycle ratcheting mechanism produce repeatable hexagonal crimps without guessing connector size, making it especially useful when working across a range of cable cross-sections from AWG20 to AWG5. It reads like a pro tool but remains light and easy to operate for extended use.

Key Features

• Self-adjustment: The jaws automatically set to the connector cross-section so users do not need to switch dies or estimate sizes.
• Ratcheting mechanism: A full-cycle ratchet ensures each termination is fully crimped before the tool releases for consistent results.
• Hexagonal crimp profile: Six synchronously driven jaws create a serrated, six-surface crimp that improves mechanical and electrical contact.
• High-tensile construction: All stressed parts are made from oil-hardened, tempered special steel for durability under repeated loading.
• Lever action: Optimum transmission of force reduces hand fatigue, making it practical for repeated crimps on longer jobs.

Who It's For

This tool is aimed at electricians, control panel builders, and serious DIYers who regularly terminate ferrules or bootlace end-sleeves and need consistent, factory-like crimps without soldering. It is particularly useful when working with multiple wire sizes because the automatic adjustment saves time and reduces errors.

People who need precision bench crimping for very large terminals, or those who rarely crimp and prefer an ultra-low-cost one-off tool, may want to consider alternatives; heavy industrial presses or simpler single-die crimpers could be a better fit for those niche needs.

Pros & Cons

Pros

• Consistent crimps thanks to the full-cycle ratchet and precisely calibrated factory setting.
• Wide capacity range (AWG20-5) that covers common small to medium conductor sizes without die changes.
• Comfortable lever action and light weight reduce fatigue during repetitive work.
• Durable construction with hardened, tempered steel parts for long service life.

Cons

• Not intended for very large industrial terminals beyond the stated AWG range, so capacity is limited to 20-5 AWG equivalents.

Frequently Asked Questions

Does this tool require die changes?
No, the tool automatically self-adjusts to the connector cross-section across the AWG20-5 range, so manual die changes are not required.

What crimp shape does it produce?
The plier creates a hexagonal crimp profile with six serrated surfaces for secure mechanical and electrical contact.

Is it suitable for heavy industrial terminals?
It is calibrated for AWG20-5 (about 0.5 - 14 sq mm); for very large industrial terminals outside that range, a larger press or dedicated crimper is recommended.
