The DeWALT 4-1/2 in. (115mm) Small Angle Grinder is a professional-grade corded grinding tool built for demanding jobsite applications. Powered by an 11 amp AC/DC motor that delivers 11,000 RPM, this compact angle grinder is engineered to remove material fast while keeping weight and size in check - making it a reliable choice for metalworking, surface preparation, and heavy-duty cutting tasks. With a paddle switch design, tool-free wheel changes, and a protective dust ejection system, this DeWALT grinder is designed to help professionals push through tough workloads with less downtime and greater confidence.

Key Features

• Next generation 11 amp AC/DC 11,000 RPM motor provides the best power to weight/size ratio available - so you get maximum material removal without excess bulk slowing you down on the job
• Auto-off brushes shut the tool down when the brushes need replacing to avoid tool damage - protecting your investment and alerting you before costly internal wear occurs
• Paddle switch with safety lock-off prevents accidental start up - keeping the grinder stationary and safe when not actively in use
• Matching wheel flanges allow the use of common accessories - giving you flexibility to work with a wide range of standard grinding and cutting wheels
• Dust Ejection System provides durability by ejecting damaging dust and debris particles that enter the tool - extending the operational life of the grinder in dusty environments
• Over-sized brushes provide 2 times the brush life of the previous model (D28402) - reducing replacement frequency and keeping the tool running longer between service intervals
• Large spiral bevel gear provides long transmission life - delivering consistent power transfer and reducing mechanical wear during extended use
• One-Touch guard allows for 360 deg. rotation of the guard with a single action - letting you quickly reposition protection without interrupting your workflow
• Quick-Change wheel release allows tool-free wheel removal without need for a wrench - saving time during wheel swaps and reducing the need to carry extra tools
• Top-mounted and protected spindle lock button maximizes depth-of-cut without compromising durability - giving you deeper access in tight applications while maintaining tool integrity

Why This Product

• Built for heavy professional use - the 11 amp motor running at 11,000 RPM delivers aggressive material removal for metalworking and surface grinding tasks where speed and power both matter
• Engineered for longer tool life - the combination of auto-off brushes, over-sized brush design (2x the brush life of model D28402), and the Dust Ejection System means fewer interruptions and less wear on the tool in tough jobsite conditions
• Designed for quick transitions - the One-Touch guard and Quick-Change wheel release work together to minimize downtime when changing accessories or repositioning the guard, keeping productivity high
• Safer operation by design - the paddle switch with safety lock-off and the protected top-mounted spindle lock button reduce accidental activation risks while also supporting deeper cutting reach on the job

Frequently Asked Questions

What size grinding wheel does the DWE402 accept?

This grinder accepts 4-1/2 in. (115mm) wheels with a 5/8-11 UNC arbor. The matching wheel flanges also allow the use of common standard accessories without adapters.

Do I need a wrench to change the wheel on this angle grinder?

No - the Quick-Change wheel release allows tool-free wheel removal without the need for a wrench, speeding up accessory swaps on the jobsite. A wrench is included in the box for situations where you prefer to use one.

What safety features does the paddle switch provide?

The paddle switch includes a safety lock-off feature that prevents accidental start up. This means the grinder will not activate unintentionally if the switch is bumped while the tool is set down or being carried.

How does the Dust Ejection System protect the tool?

The Dust Ejection System provides durability by ejecting damaging dust and debris particles that enter the tool during operation. This helps prevent internal wear from abrasive particles and extends the working life of the grinder in dusty cutting and grinding environments.
