Why Choose Heavy Duty Oval Head Cutters?

Heavy Duty Oval Head Cutters are the ideal choice when standard precision cutters do not provide enough strength. The larger oval head design adds material around the cutting area, improving durability and allowing these cutters to handle heavier gauge soft wire and cable. They are especially popular for wire harness work and applications where reliability and cutting power are essential.

Frequently Asked Questions

What is the difference between the 5811, 5812, 7811, and 7812 models?

The difference is the handle style and cutting edge:

• 5811: Standard handle with Semi-Flush cut
• 5812: Standard handle with Flush cut
• 7811: Long ergonomic handle with Semi-Flush cut
• 7812: Long ergonomic handle with Flush cut

What is the difference between Semi-Flush and Flush cutting edges?

A Semi-Flush cutter leaves a small tapered pinch on the cut end and provides excellent durability and cutting-edge life. A Flush cutter creates a flatter, cleaner cut while maintaining strong cutting performance.

What makes these cutters "Heavy Duty"?

These cutters feature a forged carbon steel construction with reinforced head and joint areas designed to withstand higher cutting demands than standard precision cutters.

What materials can these cutters cut?

These cutters are designed for soft copper wire and similar soft materials within their rated capacity. They should not be used on hardened steel, piano wire, memory wire, or other materials that exceed their specifications.

Why choose the long handle 7811/7812 models?

The long ergonomic handles provide additional leverage, making them a great option for repetitive cutting applications where reduced hand fatigue and increased comfort are important.

Are these cutters ESD safe?

Yes. The cushion grips are ESD safe, making these cutters suitable for electronics assembly and other static-sensitive environments.
