Frequently Asked Questions
What is the difference between the 5400 and 7400 Series?
The 5400 Series features standard handles for a compact feel, while the 7400 Series offers long ergonomic handles that provide additional leverage and greater comfort during repetitive cutting.
What is the difference between Flush and Razor Flush® cutters?
- Flush cutters produce a clean, nearly flat cut that balances cutting quality with edge durability.
- Razor Flush® cutters create the cleanest possible cut with virtually no remaining pinch, making them ideal for high-precision finishing work.
What is a relief head?
A relief head has material removed from the sides of the cutter head, allowing easier access underneath components and into recessed areas where conventional cutter heads may not fit.
What materials are these cutters designed for?
These cutters are designed for soft copper wire and similar non-hardened materials within their published cutting capacities. They should not be used on hardened steel, memory wire, music wire, piano wire, or other materials beyond their rated specifications.
Are these cutters ESD safe?
Yes. All Tronex miniature taper relief cutters feature ESD-safe cushion grips, making them suitable for static-sensitive electronics manufacturing and assembly environments.
