An IWISS IWS-2820M ratcheting crimp tool for small connector terminals, covering 0.08 to 0.5 mm², which is AWG 28 to 20.
A crimp is a gas tight cold weld, or it is nothing. Taken to full compression with the right die, the terminal and the conductor deform into one piece of metal with no air between them, and the joint outlives the cable. Done with pliers, it is a mechanical grip that looks identical, passes a tug test, and fails eighteen months later once moisture has found its way in. Signal circuits are where this hurts most, because the currents are too small to reveal a poor joint until it becomes an intermittent fault that takes a day to find.
The ratchet is the feature, not a convenience. It will not release until the crimp has reached full compression, so every terminal comes out the same regardless of who squeezed the handles.
Terminal families that look alike often need different dies. This one covers the JST VH, XH and NH series plus Molex KK and PicoBlade, which between them account for most small connector work on controllers, sensors and BMS harnesses.

Features
- Ratcheting action that will not release until the crimp is complete
- Covers the JST and Molex families used across controller, sensor and BMS harnesses
- Repeatable results across a whole loom, not just a careful first few
- Nylon handles, sized for repeated use rather than occasional
Compatibility
For JST VH, XH and NH, Molex KK and PicoBlade terminals on 0.08 to 0.5 mm² conductors.
It is a small signal tool. It does not crimp high voltage terminals, battery lugs or anything from 4 mm² upwards, which need a hydraulic or heavy ratchet crimper with hex dies.
Check a test crimp before you do a batch. Crimp one, cut through it, and look: a correct crimp shows solid metal with no visible voids and the insulation grip closed separately from the conductor grip.
