IWISS iCrimp Hexagonal Ratchet Crimper for End Sleeves & Ferrules 0.5-16mm2 AWG 20-5

Overview

Meet the IWISS iCrimp Hexagonal Ratchet Crimper, a compact tool designed to deliver reliable, repeatable crimps on end sleeves and ferrules across a broad wire range. Its hexagonal crimping profile uses six serrated surfaces driven by six synchronously paired jaws, helping the tool seat neatly into round terminals often found in circuit breaker panels and power distribution setups.

The self-adjusting ratchet mechanism automatically scales to the terminal diameter, promoting consistent results with every squeeze. The ergonomic handle, paired with soft-touch TPR grips, provides comfortable operation even during longer tasks. The carbon steel body is built for durability, while an anti-rust finish helps it withstand busy workshop environments.

Durability and range

The tool features multi-hardening and a corrosion-resistant finish, ready for daily use. Its capacity spans 0.5-16 mm2 (AWG 20-5) end sleeves and ferrules, making it suitable for a wide array of applications—from industrial electricians to hobbyists and DIY enthusiasts.

What you can accomplish

Use cases include quick connections in screw terminals, equipment switches, relay power supplies, car audio wiring, lamps, and speaker installations. The design emphasizes secure, repeatable crimps without excessive force, helping you work efficiently.

• Six serrated surfaces provide a stable grip on round shapes for consistent contact.
• Self-adjusting ratchet ensures the correct diameter without guesswork.
