Craftsman CMEW231: problems, parts and running costs
Checked: 2026-10-17
Summary
The CMEW231 is a corded 5-in random orbit sander with a 3.0 amp motor and a 12,000 OPM single-speed pad that starts at full speed, which one owner notes can gouge soft stock on first contact. The reported failure modes are hook-and-loop discs losing their grip after about 15 minutes and dust bags breaking off within a week. It sells at $79 at Ace Hardware and $84 at Acme Tools (2026-10), with sandpaper as the only steady running cost and a 3-year limited warranty.
Common problems and fixes
- Hook-and-loop discs lose their grip — a Lowe’s Q&A entry from June 2021 reports Craftsman hook-and-loop sanding discs stop attaching to the sander after about 15 minutes of sanding; the manual names the sanding pad as a consumable part that will occasionally need replacement, so a new pad is the fix path. [4][12]
The 3-year limited warranty is listed as 36 months parts and labor, and replacement parts come through the Craftsman support site. [1][2][8]
Parts and consumables
- Sanding pad — the manual names the pad as a consumable part that will occasionally need replacement. [4]
- Belt — a replaceable belt sits between the sanding pad and the sander body; the manual names it as a consumable part. [4]
- Dust bag — one ships in the box, and replacement bags are a listed recurring cost. [1]
Yearly running cost
The sander is corded, so there is no battery or charger to buy. The steady cost is sandpaper: 5-in hook-and-loop sheets in the 8-hole pattern, with finer work burning through more of them. The belt and sanding pad are occasional replacements through the Craftsman support site, and the dust bag may need replacement. No prices for any of these were published in the sources, so a yearly dollar figure cannot be computed. [2][4][8]
When it is a good buy
At $79 at Ace Hardware or $84 at Acme Tools (2026-10) it is a fair budget buy: 3.0 amp motor, 12,000 OPM, two dust collection options, a 3-year warranty and a real parts network. [6][7]
- SKIL SR211601 — variable speed at about $32, which The Spruce tested; the better choice if you need to slow down for finish work, since the CMEW231 has no speed control. [19]
- Makita BO5041 — about $129, and the Bosch ROS20VSC about $69 per Pro Tool Reviews; these are the alternatives to weigh once the price rises past $100, where variable speed and independent test data become available. [18]
