Product Overview
Engineered for ultimate toughness and precision cutting, our Industrial Heavy-Duty Cr-V Combination Pliers Series (Models: W28449, W28450, W28451) are built to handle the most demanding mechanical, electrical, and construction jobs. Drop-forged from premium Chrome Vanadium (Cr-V) steel and subjected to overall heat treatment, these pliers feature induction-hardened cutting jaws that reach an exceptional hardness of HRC60. Capable of cutting hard metals up to HRC45 hardness, this tool delivers high leverage, effortless cutting performance, and long service life.
Key Features & Performance Highlights
- Drop-Forged Premium Cr-V Steel:
Drop-forged from high-grade Chrome Vanadium steel with complete body heat treatment, providing exceptional structural rigidity, anti-deformation strength, and superior fatigue resistance. - HRC60 Induction-Hardened Jaws:
Precision-machined cutting edges undergo localized high-frequency induction hardening, reaching an extraordinary hardness of HRC60 for clean, long-lasting sharpness without edge chipping. - Powerful Cutting Capacity up to HRC45 Material:
Specially engineered leverage and jaw geometry allow operators to cut through tough wires and hard metallic rods with a hardness up to HRC45 easily, saving time and physical effort. - Optimal Ergonomics & Jaw Geometry:
Features deep jaw depth (up to 34mm) and wide opening capacity (up to 37mm) with anti-slip ergonomic handles for maximum gripping force and comfort.

FAQ
Q1: What does the HRC60 rating on the cutting edge mean?
A1: HRC60 indicates the hardness level of the cutting edge achieved via high-frequency induction quenching. This high hardness level ensures the jaws remain sharp and resistant to wear or denting over long periods of heavy use.
Q2: What materials can be cut with the HRC45 cutting capacity?
A2: A cutting capacity of HRC45 means these pliers can cut hard metallic materials such as hard steel wire, medium-hard springs, iron nails, and steel cables up to HRC45 hardness without damaging the tool.
Q3: Which size should I choose among 160mm, 180mm, and 200mm?
A3:
- 160mm (W28449): Compact and lightweight, suitable for precision wiring and light maintenance.
- 180mm (W28450): The standard universal size for electrician and general maintenance work.
- 200mm (W28451): Maximum length and leverage, ideal for heavy-duty industrial cutting and clamping.
Q4: What is the packaging setup for bulk export shipments?
A4: All three models are packaged with 5 pieces per inner box and 50 pieces per export master carton, optimized for secure stacking and container space saving.
Q5: Can we request custom handle colors and laser-engraved branding?
A5: Yes, we offer full OEM services including custom handle color matching (TPR/PVC), laser logo engraving on the pliers head, and custom packaging.
