Best Electric Sander for Metal (2026)

Compared on paper

Specifications are as published on each listing and collected 1 November 2026. Speed figures come from the titles and bullets, and warranty terms are quoted only where a listing states a term.

How the points were given

Each sander is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A safety score above zero needs a stated safety feature or listing, and none of these listings states one, so safety earns no points across the picks. A warranty score above zero needs a stated term, and only the ThinkLearn listing states a term. The compare table shows each raw total.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

Every listing here states a speed figure and a sandpaper kit, and every corded listing states amps while the cordless listing states battery figures instead. Dust collection varies: a dust bag, a detachable dust box, and a dust box with a vacuum adapter all appear, while the cordless listing states no dust collection at all. Warranty terms are thin across the set, with a stated term on the ThinkLearn listing and a warranty card mentioned without a term on the GALAX listing. For metal work, the strongest signals are a high speed figure, a dust setup that keeps the bench clear, and a grit range that covers paint removal and fine finishing.

How to pick the best electric sander for metal

Speed figures

Speed figures here run from 3500 RPM on the cordless pick to 14,000 OPM on the HYCHIKA pick, with the GALAX and ThinkLearn picks stating a 13,000 figure. A higher figure suits paint stripping and rust removal, while a lower figure still handles light polishing and small panels. Compare the stated figure for each pick rather than assuming corded and cordless figures mean the same thing, since the cordless pick states RPM and the corded picks state OPM.

Power and cord

Corded picks state 1.6 amps, 1.1A and 1.2A with 140W on the ThinkLearn listing, so corded power is easy to compare across the set. The HYCHIKA cord measures 2m and the ThinkLearn cable measures 5.9-ft, so check outlet placement before starting a panel. The cordless pick trades corded power for freedom of movement, with a 14.4V, 2000mAh battery, up to 20 minutes of continuous runtime and a 3 hours recharge.

Dust collection

Metal dust belongs in a bag or a box, not across the bench. The HYCHIKA pick uses a dust bag with a 6-hole system, the GALAX pick uses a detachable dust box, and the ThinkLearn pick pairs a 6-hole dust box with a vacuum adapter sized at 32 mm for a household vacuum cleaner. The cordless pick states no dust collection, so plan for cleanup after sanding.

Sandpaper kits

Kits here include 12 sheets, 15 sheets, 20 sheets and 36 sheets, with grits from P60 to P320 across the set. Coarse grits suit paint removal and rust, medium grits suit smoothing, and fine grits suit finishing, and the HYCHIKA listing groups its sheets as coarse, medium and fine. The HYCHIKA and ThinkLearn listings state hook and loop fitting, which makes sheet changes quick.

Weight and grip

Weights here run from 1.65 pounds on the cordless pick to 2.5 pounds on the GALAX pick, with the ThinkLearn pick at 2 pounds and the HYCHIKA pick at 2.2 pounds. A lighter body tires the hand less on long panels, while a rubber grip helps on the GALAX and ThinkLearn picks, which both state a soft rubber grip. Compact bodies suit small panels and edges.

Garage Fit Check

• Bench space: detail sanders suit small panels and tight corners, so clear a bench area that fits the panel plus the sander body.
• Power: corded picks need an outlet within reach of a 2m cord or a 5.9-ft cable, while the cordless pick needs a charged 2000mAh battery.
• Storage: keep sandpaper kits sorted by grit, since kits here span P60 to P320 and mixing grits wastes finishing sheets.
• Before the first job: check that the dust bag or dust box is fitted, and that the vacuum adapter is seated on picks that include an adapter.

FAQ: garage tools

What speed figure matters for metal sanding?

For paint stripping and rust removal, a higher figure helps: the HYCHIKA pick states 14,000 OPM, the GALAX and ThinkLearn picks state a 13,000 figure, and the cordless pick states 3500 RPM. Match the figure to the job, with higher figures for removal and lower figures for light polishing.

Does a cordless sander suit metal work?

It can, for small panels and short sessions: the cordless pick states 3500 RPM, a 14.4V, 2000mAh battery, up to 20 minutes of continuous runtime and a 3 hours recharge. For long paint-stripping sessions, a corded pick avoids the recharge pause.

What grit range should a metal sanding kit cover?

Look for coarse grits for paint and rust removal, medium grits for smoothing, and fine grits for finishing. Kits here span P60 to P320. The cordless kit covers that full span, and the other kits cover narrower ranges within it.

How does dust collection differ across these picks?

The HYCHIKA pick uses a dust bag with a 6-hole system, the GALAX pick uses a detachable dust box, and the ThinkLearn pick pairs a 6-hole dust box with a vacuum adapter for a household vacuum cleaner. The cordless pick states no dust collection, so plan cleanup separately.

Is a warranty stated for every pick here?

No. Only the ThinkLearn listing states a term, a 1 Year Manufacturer Warranty. The GALAX listing mentions a warranty card without stating a term, and the remaining listings state no warranty term.
