The Tronex Miniature Oval Head Relief Cutters are precision cutting tools designed for delicate applications where maximum accessibility and control are required. Featuring a miniature oval relieved head, these cutters provide an extremely low-profile design that allows access into tight spaces while maintaining the strength and durability of an oval head cutter.
The relieved head design removes material from the sides of the cutter head, allowing easier access underneath components and into confined areas. These cutters are ideal for fine electronics assembly, miniature component work, jewelry applications, and precision manufacturing where visibility and accuracy are critical.
This product page includes the following models:
- 5312 / 7312 – Flush Cut
- 5313 / 7313 – Razor Flush® Cut
The 5300 Series features standard handles, while the 7300 Series includes long ergonomic handles for improved leverage and reduced hand fatigue during repetitive cutting tasks. Tronex precision cutters feature ESD-safe double cushion grips, protective tip caps, and carefully aligned cutting edges for reliable professional performance.

Why Choose Miniature Oval Relief Cutters?
Miniature Oval Relief Cutters are designed for situations where standard-size cutters are too large or difficult to maneuver. The smaller oval head provides better access and visibility, while the relieved profile allows the cutter to reach around and underneath components without sacrificing the strength needed for reliable cutting performance.
Choosing the Right Cut Style
Flush Cut (5312 / 7312)
Provides a clean, nearly flat cut while maintaining excellent cutting-edge durability. A great choice for general precision electronics and assembly applications.
Razor Flush® Cut (5313 / 7313)
Designed for the cleanest possible cut with minimal remaining wire protrusion. Ideal for applications where surface finish and minimal cleanup are important.
Frequently Asked Questions
What is the difference between the 5312/7312 and 5313/7313 models?
The difference is the cutting edge style:
- 5312 / 7312: Flush cut for a clean finish with excellent durability
- 5313 / 7313: Razor Flush® cut for the cleanest possible finish with minimal protrusion
What is the difference between the 5300 and 7300 Series?
The 5300 Series features standard handles for compact control, while the 7300 Series features long ergonomic handles that provide additional leverage and comfort during extended use. Tronex model numbers beginning with “5” indicate standard handles, while models beginning with “7” indicate long ergonomic handles.
What does "relieved head" mean?
A relieved head has material removed from the sides of the cutter head, creating a lower-profile design that improves access underneath components and in tight work areas.
What materials can these cutters cut?
These cutters are designed for soft copper wire and similar soft materials within their rated capacities. They should not be used on hardened steel, piano wire, memory wire, or other materials outside the specifications.
Are these cutters good for electronics work?
Yes. Their miniature head size, low-profile design, and ESD-safe grips make them especially useful for electronics assembly, PCB work, and other precision applications.
Are Tronex miniature cutters ESD safe?
Yes. Tronex cutters feature static-dissipative ESD-safe grips designed for use in electronics and other static-sensitive environments.
Do these cutters include a protective cap?
Yes. Tronex cutters include a protective tip cap to help protect the cutting edges and prevent accidental damage during storage.
