Angle grinders are essential tools in metalworking and construction, but with regular use comes a risk that’s often overlooked: Hand-Arm Vibration Syndrome (HAVS). This condition, caused by prolonged exposure to vibration, can lead to tingling, numbness, and permanent damage to your hands and arms. It’s a serious issue that affects thousands of workers globally, yet it doesn’t get the attention it deserves.

At FEIN, we believe that the tools you use shouldn’t come at the expense of your health. That’s why choosing the right angle grinder is about more than just performance—it’s about finding a tool that’s safe, comfortable, and built to last. In this guide, we’ll walk you through what to consider when selecting an angle grinder, while highlighting two exceptional options from FEIN: the Protago Safety Angle Grinder and the CG 15-125 BL.

Why HAVS Should Influence Your Tool Choices

Hand-Arm Vibration Syndrome (HAVS) is a progressive condition caused by long-term exposure to the vibrations emitted by power tools. Symptoms often start small—tingling or numbness in the fingers—but can escalate to pain, loss of dexterity, and even permanent damage to nerves and blood vessels.

For professionals who rely on tools like angle grinders daily, HAVS isn’t just an inconvenience; it’s a potential career-ending condition. That’s why reducing vibration exposure should be a priority when choosing your equipment. FEIN’s angle grinders, like the Protago and CG 15-125 BL, are designed with advanced vibration-reducing technology, helping you work safely without sacrificing productivity.

How to Choose the Right Angle Grinder

Finding the right angle grinder means balancing performance with safety and comfort. Here are the key factors to consider:

1. Prioritise Low Vibration Levels

The best way to combat HAVS is to start with the right tool. Look for grinders specifically engineered to dampen vibration, allowing you to work longer and safer. FEIN’s Protago and CG 15-125 BL are industry leaders in minimising vibration impact.

2. Opt for an Ergonomic Design

A grinder that feels comfortable to hold and use can make all the difference during long jobs. Lightweight, well-balanced tools with adjustable handles reduce fatigue and help you maintain control.

3. Match the Grinder to Your Job

The size and disc diameter of your grinder should suit your application. For versatility, a 125mm grinder like the CG 15-125 BL offers precision and power, while smaller grinders are ideal for detailed work.

4. Check for Safety Features

Modern grinders come equipped with features like soft starts, anti-kickback systems, and automatic shut-offs to keep you protected while working.

5. Consider Dust Protection

Dust from grinding can damage your tool and pose a health risk. Grinders with sealed components and efficient dust extraction systems are better for both you and your equipment.

Protago Safety Angle Grinder

The Protago Safety Angle Grinder puts user protection at the forefront:

CG 15-125 BL

The CG 15-125 BL combines durability, comfort, and precision:

  • Low HAVS Levels: Keeps vibration exposure to a minimum for safer, longer operation.
  • High-Performance Brushless Motor: Provides excellent power while reducing maintenance.
  • Compact and Versatile: Perfect for confined spaces and detailed work.
  • Advanced Dust Protection: Extends the life of the tool by keeping components clean.

This grinder is a reliable companion for demanding projects, offering a balance of power and safety.

FEIN CG 15 BL - LASTS MUCH LONGER, BUT COSTS MUCH LESS!
  • The fully enclosed brushless FEIN PowerDrive motor provides the perfect protection from aggressive ceramic and mineral dusts. Sooner or later, these dusts will destroy universal motors. The new innovative FEIN motor concept reliably prevents this from happening and thereby extends the tool’s life by more than 60%.
  • The technology in the FEIN PowerDrive motor manages without carbon brushes. This translates into few wearing parts, longer service intervals and lower maintenance costs. The extremely efficient 1500 W motor consumes 200 W less power and yet is more effective than a 1700 W universal motor, which cuts energy costs.
