FAQs

What makes the Excelta 7142E different from other cutters?

The 7142E is part of Excelta’s premium Lazer Line® series and carries a 5-star precision rating, the highest in their line. Its medium oval head provides stability while cutting, making it easier to achieve consistent flush cuts. Unlike general-purpose cutters, the 7142E leaves no pinch marks on soft wires, which is critical in electronics and laboratory work where clean connections and precise results are required.

Its medium oval head provides stability while cutting, making it easier to achieve consistent flush cuts. Unlike general-purpose cutters, the 7142E leaves no pinch marks on soft wires, which is critical in electronics and laboratory work where clean connections and precise results are required. The Excelta 7142E is engineered to cut soft wire ranging from .001" to .042" in diameter. This includes copper, gold, aluminum, and other soft alloys typically found in electronics and fine assembly work. It is not recommended for hardened steel or piano wire, as using it outside of specification can damage the induction-hardened cutting blades.

What does ESD-safe grip mean?

The cushioned grips on the 7142E are designed with electrostatic discharge (ESD) protection rated at 10¹⁰ ohms/sq. This ensures that static electricity is safely dissipated through the tool instead of being transferred to sensitive electronic components. For technicians working on circuit boards, microchips, or semiconductors, this feature helps prevent costly damage from static discharge.

Why is CNC machining important for this tool?

The 7142E is CNC-machined to ensure perfect joint alignment between the cutting blades. This precision machining reduces friction, allows smoother cutting action, and ensures the blades meet correctly over time. The result is a tool with longer life expectancy, consistent performance, and less operator fatigue, even with repeated use.

How should I maintain the 7142E cutters?

To maximize the lifespan of these precision cutters, keep the blades clean and free of debris after each use. Avoid cutting materials beyond the rated capacity (.042" soft wire). Store them in a protective case or tool holder to prevent accidental blade damage. A light application of oil on the joint can help maintain smooth action over time, especially in high-use environments.

Who typically uses the Excelta 7142E?

These cutters are most commonly used by electronics technicians, lab researchers, and precision assembly specialists. They are ideal for anyone requiring clean, flush cuts on delicate wires, such as in circuit board work, fine soldering preparation, jewelry making, and laboratory prototyping. Their ESD-safe grips and flush-cut capability make them especially popular in electronics manufacturing and cleanroom settings.
