Ratchet Cable Cutter | HS-520A HS 325A

HS-520A / HS-325A Ratcheting Cable Cutters

The HS-520A and HS-325A cable cutters deliver professional-grade performance for cutting thick, high-strength materials with precision and minimal effort. These tools combine rugged construction with a powerful ratcheting mechanism to handle demanding cutting tasks across electrical, telecom, and industrial environments.

Designed for High-Force Cutting

This series stands out for its mechanical advantage. The integrated ratcheting mechanism multiplies hand force, allowing users to cut extremely hard materials through a sequence of controlled squeezes rather than one excessive burst of force. As a result, operators achieve cleaner cuts with greater safety and less fatigue.

Common Applications

Electrical Utilities and Contracting

• Cuts ACSR, AAC, and AAAC overhead conductors

• Suitable for heavy-gauge power transmission and distribution work

Telecommunications

• Handles large copper cable bundles

• Cuts armored and reinforced telecom cables

Industrial Maintenance and Fabrication

• Cuts thick copper busbars

• Handles steel wire rope, bolts, and metal rods

Salvage and Demolition

• Cleanly cuts rebar, chains, and other tough metals

• Designed for repeated use in harsh environments

Key Safety and Usage Guidelines

• Never use on live lines. Always confirm that circuits are fully de-energized before cutting.

• Seat the cable completely in the jaw throat before applying pressure.

• Use the ratcheting action as intended—allow the mechanism to do the work rather than forcing a single cut.

• Clean and lightly oil the blades to prevent corrosion and maintain smooth operation.

• Inspect the tool before each use for cracks, blade damage, or ratchet malfunction.

Construction and Materials

Blades

The cutters use forged alloy steel blades, often chrome-plated for corrosion resistance. Users can replace the blades to extend tool life and maintain cutting performance.

Handles

Long handles with insulated comfort grips improve leverage and control. The insulation typically carries a 1000V rating for low-voltage work, though standard safety practices always apply.

Build and Weight

With a typical weight of 3.5–4.5 kg (8–10 lbs), these cutters prioritize durability and stability for heavy-duty applications.

Brand and Model Overview

These cutters are commonly associated with HUBIX, a Korean manufacturer known for professional-grade tooling, though similar designs exist across other brands. The model numbers (HS-520A and HS-325A) generally reference maximum cutting capacity in square millimeters for copper or aluminum conductors.

Cutting Capacity

• Copper cable: Up to 520 mm² (1000 MCM) or 325 mm², depending on standard

• Aluminum cable: Up to 620 mm²

• Soft/stranded copper: Up to 520 mm²

• Hard-drawn copper: Up to 325 mm²

• Steel rod: Up to 16 mm diameter
