Bolt cutter is a tool designed for cutting through hard materials like bolts, chains, padlocks, and wire fences.
Product Specifications
Bolt cutters are characterized by several key specifications that determine their performance and suitability for different tasks:
Cutting Capacity: This refers to the maximum diameter of material the cutter can handle.
Soft wire up to Ø 6 mm
Medium-hard wire up to Ø 5.2 mm
Hard wire up to Ø 4.0 mm
Piano wire up to Ø 3.6 mm
Blade Hardness: High-quality bolt cutters feature induction-hardened blades with a hardness of approximately 62 HRC (Rockwell C scale) for durability.
Handle Design: Modern bolt cutters often have ergonomic multi-component grips for comfort and better handling. Some models feature slim grips without collars for easier transport.
Common Types of Bolt Cutters
Compact Bolt Cutters: Designed for portability and ease of use in tight spaces. The size is 8''.
Heavy-Duty Bolt Cutters: Used in industrial settings for cutting large bolts and nuts.
Manufacturing Process
The production of bolt cutters involves precision engineering and quality materials:
Material Selection: High-carbon steel or chromium-vanadium alloys are commonly used for their strength and durability. The material choice affects the tool's performance and lifespan.
Hnadles are usually made from the Steel Pipe by giving required shape at the ends to fit with jaws. A soft rubber grip is always fitted on the end of handles for easy gripping.
Forging: The basic shape of the cutter is created through hot forging, which aligns the metal's grain structure for increased strength.
Machining: Critical components like the cutting edges are precision-machined. As with screwdriver bit production, this stage often uses automated CNC machines for consistency.
Heat Treatment: The cutting edges undergo induction hardening to achieve the desired hardness (around 62 HRC). This process increases wear resistance while maintaining toughness.
Surface Treatment: Jaws are usually sand blasted and coated with antirust oil for corrosion resistance and aesthetic appeal. Handles are usually painted. Rubber grips comes win different colors.
Assembly: Handles are fitted with multi-component grips for comfort, and all components are assembled with precision joints for optimal leverage.
Quality Control: Each cutter undergoes rigorous testing to ensure it meets specifications for cutting capacity and durability.
