WORX WX801L 20V 3-inch Mini Cutter: problems, parts and running costs
Checked: 2026-10-19
Summary
A compact 2.4 lb cordless 3-inch mini cutter with no reported model-specific failure modes — the known limits are a brushed motor, a small 1.5 Ah battery and no dust collection that makes concrete cutting a silica-dust concern. Running costs are replacement 3-inch discs and, if the included battery is too small, a larger Power Share pack; no subscription exists. It is a good buy at the $89.99 WORX direct kit price (2026-10) for owners already in the Power Share ecosystem, and weak value above $110.
Common problems and fixes
- Brushed motor with no published power figures — WORX publishes no wattage or torque for this model, and the 19,000 RPM is a no-load speed with no loaded figure from WORX or any independent source. There is no fix; it is a spec gap to weigh before buying. [1]
- Wrong guard for the disc type is a safety issue — the metal grinding guard (rated to 1000°F) and the plastic cutting guard (rated to 205°F) are for different discs; both adjust tool-less. Match the guard to the disc. [1]
- Price variance between retailers — the same kit is $89.99 at WORX direct and $119.99 at Acme Tools; buy direct. [1][5]
Parts and consumables
Yearly running cost
No yearly total is published in the sources. There is no battery subscription and no proprietary consumable lock-in beyond the Power Share battery platform; charging electricity is not quantified in the sources.
When it is a good buy
October 2026 prices: WORX direct lists the kit at $89.99 and the bare WX801L.9 at $89.99 regular, with some configurations at $114.99; Acme Tools lists the kit at $119.99. [1][3][5]
- $90 or less: reasonable for light-duty cutting in tight spaces, especially for owners already in the WORX Power Share ecosystem; the 3-year warranty and the included battery and charger add value.
- $91–110: fair value.
- $111–130: weak — at $119.99 larger brushless cordless angle grinders become reachable.
- Above $130: poor value for this tool class.
Named alternatives:
- WORX WX812L 4-1/2-inch angle grinder — $189.99 at WORX direct, 2026-10; the better pick when you want a brushless motor and full-size grinding power instead of one-handed tight-space work. [1]
Warranty: 3-year limited. [1]
