DEWALT DW758 Bench Grinder Review — 8-Inch Corded Shop Grinder

What the Research Shows

The DEWALT DW758 is an 8-inch corded bench grinder positioned as a workhorse shop tool for sharpening, deburring, and general metalworking tasks. Published retailer listings from Home Depot and Lowe’s confirm the DW758 as a well-established model in DEWALT’s stationary tool lineup, and independent published assessments — including Bob Vila’s buyer’s guide coverage of the bench grinder category — reference DEWALT’s 8-inch bench grinder as a benchmark “Best Overall” pick, praised for power, stability, and user-friendly operation relative to competing models.

Research across woodworking and metalworking forum communities, including detailed discussion threads on garage and workshop forums, confirms the DW758 has a long track record of shop use, with owners weighing in on both its strengths and specific quality-control considerations that are important to communicate transparently.

Grinding Performance

As an 8-inch bench grinder, the DW758 provides a larger wheel diameter than the more common 6-inch class, which published assessments note translates to a larger effective grinding and sharpening surface and generally better heat dissipation during extended grinding sessions — a meaningful consideration for shop tasks like sharpening lawn mower blades, chisels, drill bits, and other edged tools where sustained contact with the wheel generates heat. The stationary, bench-mounted design provides the stability needed for precise, repeatable grinding angles that handheld grinders cannot match.

Published assessments position 8-inch bench grinders generally as the preferred choice over 6-inch models for shop owners who do frequent or heavier grinding work, since the larger wheel mass and surface area reduce the rate of wheel wear and provide more consistent performance under sustained use.

Build & Design Considerations

Independent published forum discussions, including a detailed Reddit r/Dewalt thread and a garage workshop forum discussion specifically about the DW758, provide a more nuanced picture than a simple star rating alone. Multiple published owner reports describe the 8-inch DW758 units as having noticeable wheel wobble on first run — a quality control issue that a subset of owners experienced requiring wheel truing or, in some cases, wheel replacement before the grinder ran smoothly. Community discussions note that this appears to be a specific pattern with the 8-inch version of this DEWALT grinder line, with some forum participants suggesting DEWALT’s quality control on this model has been inconsistent across production runs.

At the same time, other published owner reports in the same discussion threads describe long-term satisfaction with the tool once initial wheel-balance issues were addressed, and comparisons to alternative brands like Jet and older American-made grinders come up frequently in these discussions, with some forum participants recommending buyers compare options carefully rather than assuming any single 8-inch grinder is without tradeoffs.

Where It Falls Short

Research identifies this as a case where transparency about mixed feedback is especially important. Multiple independent published forum sources specifically report wheel wobble as an out-of-box issue on a portion of DW758 units, which may require the buyer to true or balance the wheel before achieving smooth operation — an inconvenience that should factor into purchase expectations. Community discussion threads describe DEWALT’s quality control on this model as inconsistent across individual units, with experiences ranging from fully satisfied long-term owners to those who experienced early issues. Buyers considering the DW758 should research current owner feedback at the time of purchase and be prepared to true the wheel if wobble is present upon setup, a common but not universal experience reported in published community sources.

Value Assessment

At approximately $159, the DEWALT DW758 sits at a reasonable mid-range price point for an 8-inch bench grinder, and its inclusion in the DEWALT lineup and coverage in independent buyer’s guides support its general positioning as a capable shop tool for sharpening and grinding tasks. However, research surfaces a genuine and recurring quality-control theme in published owner and forum discussions — wheel wobble on a portion of units — that we believe is important to disclose directly rather than omit. For workshop owners and DIYers who want a larger 8-inch grinding surface and are comfortable performing basic wheel-truing if needed, the DW758 remains a reasonable option backed by DEWALT’s brand support; buyers who want the highest confidence in an unbalanced-wheel-free experience out of the box may want to compare additional current reviews or consider alternative brands referenced in community discussions, such as Jet, before purchasing.
