Understanding Angle Grinders for Metalwork

Angle grinders are versatile power tools that spin abrasive discs at high speed. The abrasive surface grinds away material or cuts through it. For metalwork, this means fast cutting through steel, efficient weld removal, and quick surface preparation.

For metal fabrication, angle grinders excel at specific tasks. Cutting through steel plate, rebar, and pipe happens in seconds. Grinding welds smooth creates professional-looking joints. Removing rust and paint prepares surfaces for welding or finishing.

The tool works by spinning an abrasive wheel at high speed, typically 8,000-12,000 RPM. For cutting, thin abrasive wheels slice through metal quickly. For grinding, thicker wheels or flap discs remove material and smooth surfaces.

Buying Guide: Choosing the Right Angle Grinder for Metalwork

Selecting the right angle grinder for metalwork requires understanding several key factors. The wrong choice means frustration, poor performance, and potential safety issues.

Corded vs Cordless for Metalwork

Corded grinders deliver continuous power without battery concerns. For fabrication shop use where outlets are available, corded models make the most sense. You’ll never deal with batteries dying mid-cut, and power output remains consistent.

Cordless grinders provide mobility that corded tools can’t match. On-site metalwork, outdoor fabrication, or working away from power outlets makes cordless essential. Modern brushless cordless grinders approach corded power levels.

For metalwork specifically, many fabricators own both. A corded grinder handles continuous shop work, while a cordless model serves for mobile tasks and quick jobs.

Power: Amps and Voltage Matter

For corded grinders, amps indicate power output. Higher amps mean more cutting power and better performance under load. Here’s what amp ratings mean for metalwork:

• 5-7 amps: Light sheet metal and thin tubing under 1/8 inch
• 7-9 amps: Medium steel, pipe, and rebar from 1/8 to 1/4 inch
• 9-11 amps: Thick steel plate and heavy fabrication from 1/4 to 1/2 inch
• 11-15+ amps: Industrial thick metal cutting over 1/2 inch

For cordless models, voltage matters more. 18V and 20V systems work for most metalwork. For heavy cutting, higher-voltage platforms like 40V or 60V deliver more power and runtime.

Safety Features for Metal Fabrication

Metal fabrication creates specific hazards that angle grinder safety features address. Kickback occurs when the wheel binds in the material, causing violent tool rotation. Kickback protection senses these events and stops the wheel.

Electric brakes stop wheel rotation quickly after releasing the trigger. This reduces injury risk and improves productivity. Paddle switches require two actions to activate, preventing accidental startup.

Dust ejection systems direct metal particles away from the motor. This extends tool life in metal fabrication environments where dust and debris are constant.

Size Selection for Metalwork Tasks

Angle grinder wheel sizes determine cutting depth and application suitability:

• 4-1/2 inch: Most versatile for general metalwork, fits in tight spaces
• 5-6 inch: Deeper cuts, more power for thicker materials
• 7-9 inch: Heavy fabrication, large diameter cuts, industrial use

For most metal fabrication, 4-1/2 inch grinders provide the best balance of versatility and power. Larger wheels cut deeper but are heavier and harder to control.

Switch Type: Paddle vs Slide

Paddle switches require constant pressure or feature a lock-on mechanism. They’re safer because accidental release stops the tool immediately. Most professionals prefer paddle switches for metalwork.

Slide switches lock in place for continuous operation. They can be trickier to operate with welding gloves. Some metalworkers prefer them for extended grinding sessions.
