SN-58B Ratchet Crimping Tool 0.25-1.5mm²

Achieve consistent, professional-quality crimps every time with the SN-58B Ratchet Crimping Tool, a precision hand crimper built for open-barrel and insulated terminals in the 0.25-1.5mm² (AWG 23-16) wire range. Combining the functions of the popular SN-28B and SN-48B crimpers into one tool, it handles a wide variety of common connector pitches without needing to switch between different crimpers.

The tool’s ratcheting mechanism won’t release until a full, uniform crimp cycle is complete, eliminating the inconsistent, under-crimped connections that come from manual squeeze-style crimpers. Its four double-crimp jaw stations crimp both the wire conductor and insulation grip in a single action, supporting common terminal pitches including 2.54mm, 2.8mm, 3.96mm, 4.8mm, and 6.3mm, covering Dupont, JST, Molex, and similar open-barrel connector styles. EDM-machined jaws deliver precise, repeatable crimps, while the carbon steel body and comfortable dual-material handle grips hold up to extended use without fatiguing your hand.

This crimper is a go-to tool for hobbyists and makers working on Arduino projects, 3D printer wiring, PCB jumper cables, ATX/EPS/PCIe/SATA power pins, RC electronics, and general automotive or DIY wiring repairs. Its self-releasing lock mechanism and marked jaw stations make it easy to identify the correct crimp cavity, speeding up repetitive terminal work.
