Meet the Aiderar 4-1/2-inch cordless angle grinder, a compact, high-performance tool designed for quick DIY fixes and small metal projects. Built to pair with your existing DeWalt 20V MAX batteries, this tool-only grinder brings reliable power, precise control, and a balanced feel to your project bench. Whether you’re smoothing welds, removing rust, or making clean cuts, this grinder is ready when you are—without the burden of extra batteries.

Power, control, and efficiency

The brushless motor delivers steady, efficient performance with less downtime and maintenance. You’ll notice smoother starts and consistent power under load, helping you stay productive from start to finish. The soft-start technology keeps the initial surge calm, reducing kickback risk and providing a safer, more controlled experience in tight spaces or at height.

• Brushless motor for longer runtime and durability
• Soft-start with a variable-speed trigger for smooth power delivery
• 3-speed settings cover a range of tasks from light sanding to heavy metal cutting

Designed for DeWalt 20V MAX users

This is a smart, cost-efficient bare-tool solution that works with DeWalt 20V MAX batteries and chargers you already own. For heavy loads, a higher-capacity battery (4.0Ah or more) is recommended to maintain performance without interruptions.

• Tool-only design saves on duplicate batteries
• Seamless compatibility with your existing DeWalt 20V MAX ecosystem
• Practical for hobbyists and light professional use

Safety, versatility, and guard options

two rugged metal guards allow quick task switching: keep the standard guard on for grinding and swap to the half-guard for cutting. This setup supports safer, cleaner results across jobs from rust removal to precise cuts.

• Standard guard for grinding and sanding
• Half-guard for cutting with safety in mind
• 5/8"-11 spindle compatibility with common discs
