WORKPRO 20V Cordless Angle Grinder (125 mm) with 4.0Ah battery, fast charger and 5 cutting wheels
Reviews
Product description
Overview
A cordless angle grinder is one of those tools that only feels “optional” until you try doing metal grinding or cutting without it. The WORKPRO 20V Cordless Angle Grinder is aimed at exactly that everyday sort of work: cutting, grinding, polishing and general material cleanup, with a 125 mm disc and a 7500 RPM speed for brisk action.
On paper, the deal here is a practical kit rather than just a bare tool. You get the grinder, a 4.0Ah lithium-ion battery, a fast charger, an extra handle, and five 125 mm cutting/grinding discs, plus the protective hoods and a spanner for changing discs. It’s not trying to be a pro corded replacement for everything—more a convenient, portable option for jobs around the workshop, garage or property where flexibility matters.
One thing to keep in mind: the included battery runtime is stated as working time ≥20 min, with charging time of about 100–120 min. So if your job is long and continuous, you may find yourself wanting to plan breaks or consider extra batteries (not listed here).
What to know before you buy
This model uses a battery indicator and a charge indicator, which is the sort of small detail that helps you avoid mid-job surprises. It also includes a couple of safety and convenience touches: a spindle lock for quick disc changes, and a safety switch that requires two-step activation to reduce the risk of accidental starting.
The protective cover is described as adjustable without tools. That matters in use because it can help you position the guard the way you’re working, rather than treating it as a fixed “set-and-forget” part.
Key takeaways on performance and control
The listed 7500 RPM and the 125 mm disc size are the headline specs for fast, efficient cutting and grinding. The included 4.0Ah lithium-ion battery is described as offering more power and extending service life, with working time stated as at least 20 minutes.
Control-wise, the grinder is positioned as comfortable to hold and manage. The body is slim, and it weighs only 1.75 kg (as stated), which helps if you’re doing overhead work or longer sessions. There’s also an additional handle that can be mounted in 3 positions—useful when you’re switching between cutting, grinding, or polishing angles.
Is it perfect? Probably not for everyone. If you’re expecting sustained, uninterrupted grinding for big projects, the stated charging time (100–120 min) and runtime (≥20 min) suggests it may feel more like a “tackle the job in sessions” tool rather than a continuous workhorse.
Everyday use: where it fits best
If you want a cordless tool for typical “messy” tasks—rust removal on metal, trimming and polishing, or shaping/grinding smaller sections—this kit is built for that kind of versatility. The base description also mentions stone grinding, burr grinding, and cutting stone/wood, along with metal cutting.
For a concrete example: imagine you’ve got a metal offcut with a rough edge from fabrication. You could swap to one of the included 125 mm metal grinding discs, loosen/remove it using the spindle lock for a quick change, set the guard without tools, then take the edge down in short passes. The two-step safety switch also means you’re not likely to trigger the grinder by accident while re-positioning.
What stands out (and what’s a limitation)
What really stands out is the “kit thinking”: battery + fast charger + discs, plus both protective hoods and the additional handle. For many buyers, that’s the difference between getting started immediately and having to source essentials separately.
The limitation is mainly about energy planning. With working time stated as at least 20 minutes and charging time stated as 100–120 minutes, you’ll likely want to work in bursts. Also, the runtime depends on load and material, and that’s not something the description quantifies beyond the stated ≥20 min.
Finally, it’s listed as a 20V cordless angle grinder, so if you already do heavy, long grinding sessions, you might find a higher-capacity battery setup or a different power approach more suitable—this one looks more like a practical cordless kit than a full-time production tool.

Should you buy it?
It makes sense if you want a cordless 125 mm angle grinder kit that you can use straight away, with a battery, a fast charger, an extra handle for control, and five included discs for cutting/grinding tasks. If your typical work is rust removal, trimming, polishing, deburring and general DIY workshop jobs, the flexibility of a cordless tool is likely to feel like the main advantage.
You may want to skip it if you need long, continuous sessions, because the stated working time (≥20 min) and charging time (100–120 min) point to a “pause and recharge” rhythm. It might not be a great match if you’re aiming for uninterrupted productivity or you already know you’ll burn through discs and battery capacity quickly.
Before buying, it’s worth checking that 125 mm discs are what you actually want to run, and reviewing the battery care guidance in the manual—charging after use and charging at least once every 3 months for battery health is mentioned.
Box contents and compatibility notes
The package content is clearly listed and includes: 1 x 20 V angle grinder, 1 x 4.0 Ah lithium-ion battery, 1 x quick charger, 1 x additional handle, 5 x metal grinding discs (125 mm), 2 x protective hoods, 1 x wrench, and an operating manual.
If you’re comparing this to buying a bare tool separately, the included discs and guards are the main reason it feels more ready to use straight away. Just be aware that compatibility with your existing discs/accessories isn’t detailed here, so it’s best to stick to the 125 mm disc size stated.
Care & maintenance
Battery care matters here because cordless performance depends heavily on how you manage the lithium-ion pack. The listing specifically advises recharging the battery after use, and charging it at least once every 3 months to maintain battery health.
Also, since this is a cutting/grinding tool, proper disc handling and guard positioning are part of safe day-to-day use—adjusting the protective cover without tools is a helpful touch, but it still needs to be set correctly before work.

Is it safe to use around the workshop?
