Why Choose a Relief Head Cutter?
Unlike a standard taper head, a relief head has additional material removed from the sides of the cutter head, allowing you to reach underneath components and into recessed areas that would otherwise be difficult to access. This makes relief head cutters especially valuable for dense electronic assemblies, intricate jewelry work, and other precision applications requiring maximum accessibility.
Frequently Asked Questions
What is the difference between the 5700 and 7700 Series?
The 5700 Series features standard handles for a compact feel, while the 7700 Series uses long ergonomic handles that provide additional leverage and help reduce hand fatigue during extended use.
What is the difference between Flush and Razor Flush® cutters?
- Flush cutters produce a clean, flat cut suitable for most precision applications.
- Razor Flush® cutters create the cleanest possible cut with minimal protrusion, making them ideal when a nearly flush finish is required.
What materials are these cutters designed for?
These cutters are intended for soft copper wire and similar non-hardened materials within their rated cutting capacities. They should not be used on hardened steel, music wire, memory wire, or other materials that exceed their specifications.
What is the benefit of the extra-long jaws?
The longer jaw design provides improved reach into tight assemblies and can make it easier to trim multiple component leads efficiently.
Are these cutters ESD safe?
Yes. Tronex cushion grips are manufactured from static-dissipative material, making them suitable for ESD-sensitive electronics work.
Where are Tronex cutters manufactured?
Tronex precision cutters are proudly manufactured in the USA using premium materials and are individually inspected to ensure exceptional quality and performance.
