DeWalt DWE4517 (7 in. 4 HP Corded Angle Grinder, 8,500 RPM)

Power and ergonomics

The DWE4517 is built around a 15 A motor rated at 4 HP maximum — peak, not continuous — output spinning at 8,500 RPM. Steel-cut gears in a low-profile gearcase drive a 7-inch wheel, and at 12.13 lb net (14.66 lb assembled) and 19.3 in long it is a two-handed tool. The trigger has a lock-on button, and there is no variable speed.

Home Depot owner reviews praise the power and trigger control: “Tought power, comfortable grip & trigger. Zero issues.” Another says: “Trigger control makes it easy to use. The size is perfect for grinding concrete and cutting brick.” Those are individual reviews, not measured results — no independent instrumented test of this exact model was found, and nobody has published vibration or noise numbers.

What’s in the box and running costs

DeWalt lists two included items: a 7-inch Type 27 guard, pre-adjusted at the factory to the gear case hub diameter, and a 2-position side handle. No grinding wheel, flange nuts or wrench are listed, so the real out-the-door cost runs past the sticker price. Any accessory you fit must be rated above the 8,500 RPM tool speed; over-speed accessories can fly apart.

Recurring costs are 7-inch Type 27 grinding and cutting wheels, flap discs, wire brushes and replacement brushes. There are no battery or charger costs. The manual recommends plugging into a dedicated electrical circuit: on a shared one, performance decreases.

Age, safety and owner complaints

The instruction manual (Type 5, N190393) is dated 2012 and covers this grinder alongside the 9-inch DWE4519. The age shows: the DWE4517 predates DeWalt’s PERFORM & PROTECT features, so there is no E-Clutch to stop the wheel on kickback and no brake to stop it quickly. DeWalt’s current lineup has largely moved to cordless large angle grinders and newer corded models with those features.

Owner complaints are isolated but consistent in theme: one Home Depot reviewer bought the tool twice and says both units needed parts, with bad customer service; another says a unit arrived without the bracket needed to mount a blade. These are individual reports, not defect rates. Retailer pages also disagree on wattage — Acme Tools lists 3,450 W maximum, Shipton’s Big R lists 3,000 W out — and Acme’s copy once described the grinder with 9-inch wheels, a retailer error on a 7-inch tool.

Warranty and service

DeWalt backs the DWE4517 with a 3-year limited warranty on defects in materials and workmanship, a 1-year free service contract that replaces normal-wear parts free in year one, and a 90-day money-back guarantee. The warranty applies only to the original end-user purchaser and only when bought from DeWalt or an authorized seller; claims from unauthorized sellers may be rejected.

Service runs through 20 factory-owned locations and more than 600 authorized independent repair shops in the US, with customer care at 1-800-4-DEWALT (1-800-433-9258), 7 AM to 11 PM ET daily. Automatic turn-off brushes shut the tool down when the brushes need replacement, a brush window speeds the swap, and exploded diagrams in the manual support DeWalt dealers and factory service centers.

Which model this is

This page covers the DeWalt DWE4517, the 7-inch, 15 A, 8,500 RPM corded angle grinder (UPC 885911278355). Do not confuse it with the DWE4519, a 9-inch, 6,500 RPM grinder that shares the manual, or with the DWE4559N and smaller 4-1/2-inch DeWalt grinders. The exact-model Amazon listing is ASIN B007A5YWSO.

At the $229.99 Shipton’s Big R asked in October 2026 (in-store pickup, no shipping), it suits a buyer who wants a corded 7-inch DeWalt with full warranty support. A buyer open to cordless or a newer corded grinder with a brake and E-Clutch will find weaker value at that price.
