HKS Ratcheting Crimping Tool Set 8 PCS - Quick Exchange Jaws

In this review the HKS Ratcheting Crimping Tool Set 8 PCS is evaluated for electricians, installers and serious DIYers who need a single tool to handle a wide range of terminals. The bottom line: it excels at versatility and repeatable crimps thanks to a ratchet mechanism and seven quick-change dies that cover 20-2 AWG (0.5-35mm2). For users who routinely work with ferrules, heat shrink connectors or solar connectors, this set removes the need to juggle multiple hand tools while offering a robust steel construction that feels built for regular shop use.

Key Features

• Modular dies: Seven quick-changing dies allow fast swapping between terminal types so you can switch jobs without reaching for another crimper.
• Wide crimp range: Coverage from 20-2 AWG (0.5-35mm2) means the set handles small signal wires up to larger power conductors and ferrules.
• Ratcheting action: The adjustable ratchet delivers consistent pressure and only releases after a full crimp cycle, improving repeatability and safety.
• Ergonomic handles: A contoured grip reduces hand fatigue and makes repeated crimps easier, saving time on installation tasks.
• Durable construction: HR55 steel tool body and polished dies provide longevity and maintain crimp accuracy through extended use.
• Quick-release jaws: The quick-release design swaps dies in moments for a faster workflow when moving between insulated, non-insulated, open barrel and heat-shrink connectors.

Who It's For

This set is best for electricians, solar installers, and hobbyists who need a single, flexible crimper that covers ferrules, insulated and non-insulated terminals, open barrel connectors and heat-shrink terminals. The ratcheting mechanism and die modularity make it useful where consistent crimps and quick changeovers are important.

Those who should look elsewhere include users who only crimp one type of terminal and prefer a cheaper single-die tool, or technicians who require specialized factory-calibrated hydraulic crimpers for very large gauge or production-line work beyond 35mm2.

Pros & Cons

Pros

• Versatile die set covers a broad AWG range so one tool replaces several dedicated crimpers.
• Ratcheting cycle ensures consistent crimps and reduces the chance of under-crimping.
• Sturdy HR55 steel construction and polished dies contribute to long-term accuracy and durability.
• Ergonomic handles and quick-release jaws speed repetitive work and save effort.

Cons

• Some users report mixed results on connection accuracy and crimp strength depending on wire and terminal fit, so careful inspection is still needed.
• The set covers up to 35mm2 only, so it is not suitable for very large industrial conductors.

Frequently Asked Questions

Can it crimp ferrules and insulated terminals?
Yes. The included dies are designed to handle insulated and non-insulated ferrules as well as insulated terminals.

What wire sizes does it cover?
The crimping range covers 20-2 AWG, which is 0.5-35mm2.

Is the ratchet adjustable?
Yes. The adjustable ratchet sets the crimp pressure and completes a cycle before releasing for consistent crimps.
