The DeWALT 7 in. 4HP Angle Grinder (DWE4517) is a heavy-duty corded grinding tool engineered for demanding material removal tasks, surface preparation, and cutting applications where consistent high-speed performance is essential. Powered by a 15 Amp, 120V motor delivering 4 HP and 8,500 RPM, this large-disc grinder is built to push through tough grinding jobs with speed and durability. Whether you are working through thick metal stock, aggressive surface work, or heavy-duty abrasive applications, this DeWALT corded angle grinder provides the sustained power and operator-focused design features needed to get the job done efficiently.

Key Features

• High power 4 HP (maximum motor HP) 8,500 RPM motor with overload protection - provides higher operating speeds under load, so the grinder maintains consistent cutting and removal rates even during demanding continuous use rather than bogging down under pressure.
• Epoxy coated field and armature - provides long service life against abrasion from airborne debris, protecting internal motor components from grinding dust and particulate that would otherwise degrade the motor over time.
• Low-profile gearcase - allows for work in tight areas, giving operators access to confined work zones where bulkier tools simply cannot reach.
• Automatic turn-off brushes - shut down the tool when brushes need to be changed to avoid tool damage, preventing costly motor burnout and protecting your investment by alerting you before wear becomes catastrophic.
• 2-position side handle - provides improved ergonomics for specific applications, letting the operator position the handle for maximum control and comfort depending on the orientation and direction of the grind.
• 8,500 RPM with a 7 in. wheel diameter - provides optimal material removal with 7 in. grinding wheels, maximizing the surface speed at the wheel edge for aggressive and efficient stock removal.
• Brush window - allows for quick brush replacement, reducing tool downtime and making maintenance straightforward without requiring a full teardown of the grinder housing.
• Lock-On switch with spindle lock - the lock-on trigger reduces operator fatigue during extended grinding sessions, while the spindle lock simplifies wheel changes so you spend less time swapping discs and more time working.
• AC/DC power compatibility - this tool runs off of AC/DC power, offering flexibility across a wider range of power supply conditions on the jobsite.
• Plastic housing - keeps overall tool weight manageable at 12.800 LB, reducing fatigue during sustained use compared to heavier all-metal housings.

Why This Product

• Built for heavy material removal without stalling - the combination of a 15 Amp draw, 4 HP output, and thermal overload protection means this grinder is engineered to sustain high-speed performance under real load conditions, not just at no-load RPM. Operators tackling thick metal or prolonged grinding runs get consistent results rather than interrupted work cycles.
• Designed to protect both the tool and the operator - automatic turn-off brushes prevent motor damage when brush replacement is due, while the epoxy-coated field and armature resist the abrasive particulate that fills the air during grinding work. These are durability-focused design choices that extend the useful life of the tool.
• Maintenance is straightforward, not a project - the dedicated brush window means brush replacement does not require disassembling the tool body. For a grinder that sees regular use, this translates directly into less downtime and lower maintenance burden over the tool's service life.
• Ergonomics matched to how the work actually happens - the 2-position side handle lets the operator adapt grip orientation to the task, whether grinding overhead, at an angle, or flat on a surface. Paired with the lock-on switch that eliminates the need to hold the trigger continuously, this grinder is built for extended sessions without unnecessary fatigue.

Frequently Asked Questions

What size grinding wheels is this angle grinder designed to use?

This DeWALT angle grinder is designed for use with 7 in. grinding wheels. The arbor size is 5/8 -11 UNC, which is the standard thread specification for mounting compatible 7 in. grinding and abrasive wheels. The 8,500 RPM motor speed is specifically optimized for optimal material removal at this wheel diameter.

Does this angle grinder have any motor protection features?

Yes. The DWE4517 includes both overload protection and thermal overload protection, which help prevent motor damage during sustained high-speed operation. Additionally, automatic turn-off brushes shut down the tool when brushes need to be changed to avoid tool damage, and the epoxy coated field and armature provide long service life against abrasion from airborne debris.

Can the operator change the side handle position on this grinder?

Yes. The grinder includes a 2-position side handle that provides improved ergonomics for specific applications. This allows operators to reposition the handle to best suit the orientation and direction of the grinding task, whether working flat, at an angle, or in tight spaces where the low-profile gearcase provides additional reach.

Does this angle grinder offer variable speed control?

No. The DWE4517 operates at a fixed maximum speed of 8,500 RPM and does not include variable speed functionality. It uses a Lock-On switch type, which allows the trigger to be locked in the on position to reduce operator fatigue during extended grinding work rather than requiring the operator to hold the trigger continuously.
