1. Cutting Capacity This 8 inch bolt cutter is designed for cutting softer materials up to 6 mm (15/64 inches) thick when the material hardness is up to HRC 20. For harder materials with hardness up to HRC 40, the maximum cut thickness is 4 mm (4/25 inches). Not recommended for lock locks. 2. Material and construction Jaw and body are made from high quality CR-V steel. The jaws have a hardness of HRC 60-62, delivering excellent wear resistance and superior cutting performance. The knife resists breaking or deforming, supporting long-term use. 3. Efficient leverage Classic lever design paired with a strong knife provides substantial cutting force while reducing required effort, improving work efficiency. 4. Compact and portable 8 inch size with a built-in handle lock for convenient storage. Easy to carry in a tool bag and suitable for a variety of tasks in different locations. Use scenarios - General maintenance and light fabrication: Cut soft steel bolts, fasteners, or other components up to 6 mm thick if the material is within HRC 20, enabling quick disassembly or repair work on equipment and fixtures. - Higher hardness but within limits: When dealing with materials up to 4 mm thick and up to HRC 40, this tool supports efficient cuts for maintenance tasks where stronger metals are involved. - On-site and field use: The compact 8 inch form and built-in handle lock make it easy to transport and store, allowing you to perform tasks on job sites, in workshops, or around the home without bulky equipment.
