Buy the DEWALT DW758 8-inch bench grinder (B0000224J4) if you want fast stock removal at 3,600 RPM from a 3/4 HP induction motor with a 12-1/2-inch span between the wheels for long tools; buy the WEN BG4286 8-inch slow-speed bench grinder (B097CKZY2R) if you sharpen knives, chisels and bits and want 1,750 RPM with a fine 120-grit finishing wheel so the edge stays cool, for about $42 less, and can live without the DEWALT's high-speed removal rate. The DEWALT concentrates on industrial removal speed: the maker describes a corded 8-inch (205 mm) grinder with a 3/4 HP induction motor running at 3,600 RPM, a rugged cast iron base and motor housing, precision-machined aluminum tool rests, rear exhaust ports in the wheel guards, and a 36-grit coarse wheel paired with a 60-grit medium wheel. The WEN concentrates on cool, controlled sharpening: the maker describes a soft-start 3-amp motor turning 8-by-1-inch wheels at up to 1,750 RPM, a 60-grit general wheel paired with a fine 120-grit finishing wheel, pivoting tool rests for angled grinding, and a sturdy base with pre-drilled mounting holes. On 09/16/2026 the exact DEWALT DW758 was In Stock on Amazon US at $159.00, shipped from and sold by Amazon.com with delivery as soon as Saturday, Sep 19, and the exact WEN BG4286 was available at $117.26 with only 16 left in stock (more on the way), shipped from and sold by Amazon.com with delivery as soon as Saturday, Sep 19.

Choose by your situation
| Situation | Model to consider | Main tradeoff |
|---|---|---|
| You regrind lawn-mower blades, axes and chisels with heavy stock to remove | DEWALT DW758 | 3,600 RPM removes fast but heats the edge; about $42 more than the WEN on 09/16/2026; no fine finishing wheel in the box |
| You hone kitchen knives, carving chisels and drill bits and fear bluing the temper | WEN BG4286 | 1,750 RPM is slow by design, so reshaping a damaged bevel takes longer; soft-start 3-amp motor, not an industrial-duty rating |
| You grind long tools and want room to maneuver both hands between the wheels | DEWALT DW758 | 12-1/2-inch wheel-to-wheel span per the maker; the WEN's observed pages state no equivalent span figure |
| You want the finest out-of-box edge: a dedicated finishing wheel plus angled rests | WEN BG4286 | 120-grit fine wheel included; the DEWALT's finest included wheel is 60-grit, so a fine finish needs a separately bought wheel |
| You want the longest stated warranty and a professional-duty positioning | DEWALT DW758 | 3-year limited warranty with 1-year free service and 90-day returns per the maker, against the WEN's 2-year warranty; warranty terms are maker statements, not a measured repair record |
Specifications that change the decision

|---|---|---|
| No-load speed, per maker and manual | 3,600 RPM (manual table lists DW758 at 3600 RPM; maker states 3,600 RPM) | 1,750 RPM no-load (manual specifications table and maker page) |
| Motor, per maker | 3/4 HP induction motor for industrial grinding applications | 3-amp, 120 V, 60 Hz soft-start motor; quiet yet powerful per the maker |

| Arbor, per manual | 5/8-inch (16 mm) arbors on each side for the DW758 | 5/8-inch arbor; the manual warns against wheels with an incorrect arbor size |
| Tool rests | Precision-machined aluminum tool rests to position work accurately | Pivoting work rests for angled grinding, including a grooved rest that cradles drill bits |
| Working room | 12-1/2-inch distance between wheels for larger and longer grinding applications | No between-wheel span stated in the observed maker or manual pages |

DEWALT DW758: the fast-removal pick
The DEWALT DW758 (US variant, manufacturer part number DW758) is the grinder to pick when the job is removing metal fast: mower blades, axes, chisels and deburring where a 3,600 RPM wheel and a 3/4 HP induction motor shorten the session. The mechanism is explicit in the observed maker and manual pages: the coarse 36-grit wheel hogs material, the 60-grit wheel refines, the 12-1/2-inch span keeps long tools clear of the opposite guard, and the manual pins the envelope down with a 5/8-inch arbor, a 3600 RPM ceiling to respect when buying replacements, and a 1/8-inch maximum wheel-to-rest gap. The weaknesses are just as explicit: at full speed an edge heats quickly, so quench discipline matters; the box tops out at 60-grit, so a polished edge needs a separately bought fine wheel; and at $159.00 observed it costs about $42 more than the WEN. The listing display (4.7 stars, 2,646 ratings, Amazon's Choice) signals a large installed base, not a lab result.
WEN BG4286: the cool-sharpening value pick
The WEN BG4286 (model and manufacturer part number BG4286) is the grinder to pick when the job is reviving edges rather than hogging steel: kitchen and shop knives, chisels and bits where 1,750 RPM plus the included 120-grit finishing wheel keeps temper-bluing heat away. The manual corroborates the headline claims instead of just repeating the box: 120 V 3-amp motor data, 8-by-1-inch wheels on a 5/8-inch arbor, above-1750-RPM replacement rule with ANSI B7.1 compliance, and a stated design purpose of sharpening and honing cutting tools with the appropriate accessories. The tradeoffs: reshaping a badly damaged bevel at half the DEWALT's speed takes patience; the 3-amp motor carries no industrial-duty positioning; and the stock picture (only 16 left, more on the way, at $117.26 observed) is thinner than the DEWALT's plain In Stock, so confirm availability before planning around it. The smaller review base (4.5 stars, 221 ratings) is a listing display, not a test result.
Mounting, guards and upkeep
Both grinders are corded bench tools that must be bolted down: the WEN base ships with pre-drilled mounting holes and the DEWALT manual instructs a firm bench fixing before use. Both ship with eye shields and spark deflectors, and both manuals demand real safety glasses plus hearing and dust protection on top; shields never replace glasses. Consumables differ by design speed: the DEWALT's 36-grit wheel wears fast under heavy pressure and its 60-grit wheel is the finest in the box, while the WEN's 120-grit finishing wheel gives the keener out-of-box edge but loads up if forced into heavy removal. Neither observed page prices replacement wheels with a live Amazon offer, so this comparison does not score running costs; WEN notes stocked replacement parts and DEWALT points to its service network instead.
Limits of this comparison
No independent grinding, heat, vibration or wheel-life testing was performed; speeds, grits, weights and warranty terms are maker and manual statements, and star ratings are listing displays, not measurements. Motor figures are not directly comparable across makers (3/4 HP induction against 3-amp soft-start), so treat them as positioning clues, not a measured power contest. Prices, stock, sellers and delivery dates move; every commercial fact here is dated 09/16/2026 and must be re-observed before any purchase decision is treated as current.
