Stainless steel’s nemesis revealed: the power of pliers

Stainless steel is known for its durability and corrosion resistance, making it a popular choice for various applications. However, working with stainless steel can present challenges, especially when it comes to cutting. Pliers are a versatile tool often used for cutting, but can they effectively handle stainless steel? This blog post delves into the capabilities and limitations of pliers when cutting stainless steel.

Types of Pliers

Various types of pliers exist, each designed for specific tasks. The most common types include:

• Combination Pliers: Feature a combination of a gripping jaw and a cutting blade.
• Diagonal Pliers: Also known as side cutters, designed specifically for cutting wires and thin materials.
• Needle-Nose Pliers: Have long, pointed jaws for reaching into tight spaces and gripping small objects.

Hardness of Stainless Steel

Stainless steel is a hard material, with a Rockwell hardness typically ranging from 40 to 60 HRC. The hardness of stainless steel can vary depending on its alloy composition and heat treatment.

Cutting Stainless Steel with Pliers

The ability of pliers to cut stainless steel depends on several factors:

• Plier Type: Combination pliers and diagonal pliers are the most suitable for cutting stainless steel.
• Plier Size: Larger pliers with longer handles provide more leverage for cutting.
• Stainless Steel Thickness: Thinner stainless steel can be cut more easily than thicker gauges.
• Stainless Steel Hardness: Harder stainless steel will be more challenging to cut.

Cutting Techniques

When cutting stainless steel with pliers, it is essential to use proper techniques:

• Secure the Stainless Steel: Clamp the stainless steel firmly in a vise or use a pair of locking pliers to hold it in place.
• Use Sharp Pliers: Ensure that the pliers’ cutting blades are sharp to avoid burring or tearing the stainless steel.
• Apply Gradual Pressure: Start by applying gentle pressure and gradually increase the force until the stainless steel is cut.
• Avoid Excessive Force: Using excessive force can damage the pliers or cause the stainless steel to break unevenly.

Limitations of Pliers

While pliers can cut stainless steel under certain conditions, there are limitations:

• Limited Cutting Capacity: Pliers are not suitable for cutting thick or hardened stainless steel.
• Burring: Pliers can leave burrs or sharp edges on the cut surface.
• Damage to Pliers: Repeatedly cutting stainless steel with pliers can dull the blades or damage the jaws.

Alternative Cutting Methods

If pliers are not suitable for the task, consider alternative cutting methods:

• Metal Shears: Designed specifically for cutting sheet metal, including stainless steel.
• Angle Grinder: A power tool that uses a rotating abrasive disc to cut through metal.
• Laser Cutting: A precise and efficient method for cutting complex shapes in stainless steel.

Conclusion: Evaluating Pliers’ Capabilities

Pliers can be used to cut stainless steel in certain situations, but their capabilities are limited. For thicker or harder stainless steel, alternative cutting methods should be considered. By understanding the limitations and using proper techniques, pliers can serve as a valuable tool for cutting thin or soft stainless steel.
