Pliers are one of the most essential tools in any toolbox—whether you’re a mechanic, electrician, machinist, HVAC tech, or a weekend DIY builder. At CEM Industrial Supply, we carry professional-grade pliers designed for real job-site demands: gripping, cutting, twisting, bending, pulling, crimping, and more.
If you want to understand which pliers you need — and why — this guide breaks down every major type, what they’re used for, and how to choose the right pair.
What Are Pliers? (Quick Definition)
Pliers are hand tools designed to grip, bend, twist, pull, or cut materials using leverage. They’re made of hardened steel with specially shaped jaws optimized for different tasks.
They give you precision, force, and control that fingers simply can’t.

How to Choose the Right Pliers
Choose by Task

Look for High-Quality Steel
Industrial users should prioritize:
- Chrome-vanadium steel

- Spring-loaded options for repetitive use
Pro Tips from the CEM Industrial Supply Team

- Locking pliers are perfect when you need a “third hand.”
- Choose insulated handles for any electrical application.
