Crimping Tool for Strong, Safe Crimps

Our crimping tools ensure strong, uniform crimps while preserving the terminal insulation. Designed to align wire strands perfectly, they feature color-coded (or size-marked) die nests to help you choose the right connector slot. Our tools work with:

Heat Shrink Connectors

Non-Insulated Terminals

Ferrule Terminals

Butt Connectors

Two Crimping Tool Types

Fixed Die Crimpers: Ideal for heat shrink connectors, the most common type.

Interchangeable Die Tools: With a magnetic locking mechanism for quick, easy die changes. Customize your tool for each project.

Precise Ratcheting Mechanism

Our tools feature an automatic release when crimping is complete, ensuring consistent crimping force. Adjust the crimping force via the compression wheel, and lock the connector in place before inserting the wire to ensure a perfect crimp every time. If needed, the release trigger lets you quickly open the tool and release the connector.

Ergonomic, Comfortable Handles

Designed for comfort and ease, our cushioned, ergonomic handles prevent slipping, and allow for one-handed operation—ideal for tight spaces in automotive and marine work.
