Complete Guide To Choosing Cable Cutters : Ratchet vs. Regular Types, Force Saving Principles, And On Site Selection Tips

With the rapid growth of electrical engineering and automation equipment, cable cutters have become essential tools for switchboard assembly, electrical installation, and substation maintenance. However, the market offers a wide variety of cable cutters, and many technicians often ask :

“ What’s the real difference between regular cutters and ratchet cutters ? ”
“ Why can others cut large-gauge cables so easily while my hands get inflamed ? ”

Choosing the wrong cable cutter not only reduces work efficiency but also increases the risk of occupational injury and cable deformation. This guide explains the force-saving mechanism, space limitations, and cable size considerations to help you fully understand the differences between regular cable cutters and ratchet cable cutters, and select the right tool for your job.

(１). Regular vs. Ratchet Cable Cutters :

To choose the right tool, you must first understand their structure and design logic.

Regular Type : Long handles → Relies entirely on human force → Best for small wires & open spaces.

Ratchet Type : Internal gear teeth → Segmented mechanical advancement → Best for thick cables & confined spaces.

1. Regular Cable Cutters : Classic And Simple.

Working Principle : Fully dependent on human force and the lever action of long handles.

Advantages :

Simple structure.
Durable and less prone to damage.
Affordable.
Fast opening and cutting speed.

Disadvantages :

Requires significant grip strength for large cable diameters.
Handles must be opened wide to bite into the cable, consuming a lot of space.

2. Ratchet Cable Cutters : Modern, Efficient, And Force-Saving.

Working Principle : Built-in ratchet mechanism.

Advantages :

Each squeeze advances the blade one step while locking the previous position.
Converts one large force output into multiple small squeezes.
Reduces overall effort by more than 50% .

Disadvantages :

Cutting a single cable takes slightly longer due to segmented advancement.
Higher cost.

(２). Specifications & Real-World Comparison :

Comparison Item	Regular Cable Cutters	Ratchet Cable Cutters
Force Saving	Labor-intensive, relies on arm strength	Extremely easy; even women can operate with one hand
Max Cable Size	Typically limited to ≤ 50 mm²	Easily handles 250 ~ 500 mm² and above
Handle Opening Angle	Requires > 90° to bite the cable	Only slight handle movement needed
Cut Surface Quality	Large cables may deform due to uneven force	Mechanically uniform advancement; smooth, round, burr-free cuts

(３). Three Key On-Site Selection Factors : Which One Should You Buy ?

1. Workspace Determines Tool Type :

Manholes, cable trays, switchboards : Extremely tight spaces. Regular cutters cannot open fully. → Choose ratchet cable cutters.
Open construction sites or ground work : Space is not limited; if mostly cutting small wires → Regular cutters offer faster cutting speed.

2. Cable Specification & Diameter :

≤ 50 mm² (control wires, flat white cables) : → Regular cutters are sufficient, fast, and economical.
≥ 50 mm² (high-voltage power cables) : → Strongly recommended : Ratchet cable cutters. (Using regular cutters may deform the cable and cause wrist injuries.)

3. Usage Frequency & Fatigue :

Daily continuous work : Ratchet cutters significantly reduce fatigue and extend career longevity.
Occasional maintenance / DIY : Regular cutters are a high-value basic option.

(４). Important Safety Notes For Ratchet Cable Cutters :

Even though ratchet cutters are force-saving tools, pay attention to the following to extend tool life :

Do NOT Cut ACSR Or Steel Wires.

Ratchet cutters are designed for copper and aluminum cables only. Cutting high-hardness steel will cause blade chipping and gear damage.

Maintain The Sear Teeth Regularly.

The ratchet mechanism consists of fine gear teeth. Clean metal debris after use and apply anti-rust lubricant regularly to ensure smooth operation.

(５). Conclusion : The Right Tool Makes The Work Right.

There is no universally “ best ” tool—only the one most suitable for your job site.

Fast cutting, limited budget, mostly small wires → Regular Cable Cutters
Confined spaces, large cables, wrist protection → Ratchet Cable Cutters

Investing in a high-quality ratchet cable cutter not only boosts on-site efficiency but also ensures perfectly smooth cut surfaces, providing a solid foundation for subsequent terminal crimping.
