| Speed (RPM) | Higher RPMs mean faster cutting. Some grinders have variable speed for material flexibility. | Match the speed range of the grinder to your most common materials. |
| Safety Features | Consider features like brake systems (for rapid disc stopping), restart protection, overload protection, and vibration control. | Safety should be a top priority. These features can prevent serious injury. |
| Ergonomics | Grinders can be heavy. Consider the weight, handle design, auxiliary handles, and balance of the tool. | Comfortable tools mean you can work longer and more safely. |
| Battery Compatibility | If you own other cordless tools, choosing an angle grinder in the same battery system offers convenience and cost savings. | Can save you money long-term and reduce the number of batteries/chargers you need. |
| Additional Features | Look for features like tool-free disc changes, spindle locks, dust protection, and soft-start for convenience and longevity. | These can make your life easier and extend the tool’s lifespan. |
Power and Performance
For most DIY tasks, a 4 to 6-amp battery-powered angle grinder will work great. Higher amperage means more power, so go for an 8 amp or more model if you plan to use it frequently or for demanding jobs like cutting steel. RPMs indicate how fast the disc spins – higher RPMs will cut faster, while lower RPMs provide more control. A tool with multiple speed settings gives you the most flexibility.
Battery and Charger
Look for a lithium-ion battery that provides enough runtime for your needs. Higher amp hour (Ah) ratings mean longer run times. A charger that fully recharges in under an hour is ideal. Some models offer swappable battery packs so you can keep working.
Disc Size and Safety
For most people, a 4 1/2 or 5-inch disc size is the most versatile. Larger discs cut more aggressively but the tool may be harder to handle. Look for safety features like a paddle switch, locking button, or trigger guard to prevent accidental start-ups. An adjustable guard helps contain sparks and debris.
Ergonomics and Design
Hold a few different models to find one that feels balanced and comfortable in your hands. A compact, lightweight design is easier to maneuver in tight spaces. Some angle grinders feature vibration-reducing designs and padded grips for more comfortable extended use.
Additional Features
Useful extras include a spindle lock for quick disc changes, tool-less guard adjustment, onboard wrench storage, and LED work lights. Dust extraction ports allow you to connect a vacuum for a cleaner work area. Some models offer tool-free disc changes for added convenience.
By considering these factors, you’ll find a safe, high-performing battery angle grinder suited to your needs and budget. Time to get grinding!
Cordless vs Corded Angle Grinders: Pros and Cons
When shopping for an angle grinder, one of the first decisions you’ll make is whether to go cordless or corded. Each type has its advantages and disadvantages, so consider which factors are most important for your needs.
Cordless Angle Grinders
- Portability: Work anywhere without being limited by cords or power outlets. Great for remote job sites or awkward angles.
- Safety: Less tripping hazard compared to long cords.
- Convenience: No tangled cords to manage, easy tool switching with compatible battery systems.
- Limited Runtime: Batteries eventually run down and need recharging, potentially interrupting your work.
- Generally Less Powerful: Compared to top-tier corded grinders, battery-powered versions may lack some raw cutting power.
- Higher Cost: Usually more expensive than corded equivalents, plus the cost of batteries and chargers.
Corded Angle Grinders
- Unlimited Power: Consistent performance as long as it’s plugged in. Ideal for heavy-duty, extended tasks.
- Often More Powerful: Many corded grinders deliver maximum power that exceeds cordless models.
- Lower Cost: Typically cheaper than cordless counterparts, especially when factoring in batteries.
- Limited Mobility: The working range is constrained by the cord length and the availability of power outlets.
- Trip Hazard: Cords present a trip hazard, especially in cluttered workspaces.
- Less Versatile: Not ideal for awkward positions or remote locations without power.
Cordless (Battery-Powered) Angle Grinders
Cordless angle grinders offer the ultimate in portability and convenience. Since they run on rechargeable battery packs, you can use them anywhere without being tethered to an outlet. Battery life and power have improved a lot in recent years, but cordless models still can’t match the raw power and extended run times of their corded counterparts.
Cordless angle grinders are also typically more expensive, especially if you need to buy additional battery packs. However, for light to medium tasks where maximum power isn’t essential, a cordless angle grinder can be a great choice.
Corded (Electric) Angle Grinders
If you need an angle grinder for heavy-duty, extended use, a corded model is probably your best bet. Corded angle grinders provide virtually unlimited power and run time, as long as you have access to an outlet. They are also typically more affordable than comparable cordless models. The downside is that you are limited by the length of the power cord and how close you are to electrical outlets. For some people, dealing with a cord can also be inconvenient.
In the end, choosing between cordless or corded comes down to balancing power, convenience, and budget. For most DIYers and homeowners, a cordless angle grinder will handle typical light tasks efficiently and without hassle. For professional use or heavy-duty needs, a corded model is probably the way to go. The good news is, whichever you choose, today’s angle grinders are more powerful, durable, and affordable than ever before.
How to Use and Maintain Your Battery Angle Grinder
Charging the Battery
The first thing you’ll want to do is fully charge the battery for your cordless angle grinder. Plug the charger into the wall and connect the battery, then leave it charging until the indicator light turns green. Most batteries take 3 to 5 hours to reach maximum capacity. Be sure to charge the battery after each use to keep it ready when you need it.
Installing the Grinding Disc
With a fully charged battery in place, you’re ready to install your chosen grinding disc. Loosen the spindle lock or disc nut in the center of the grinder, place the disc over the spindle, and hand-tighten the nut. Then press and hold the spindle lock button or lever, and use the included wrench to securely tighten the nut. Release the lock button and ensure the disc spins freely without wobbling.
Adjusting the Guard
The guard on your angle grinder protects you from debris and sparks. Loosen the guard adjustment nut or lever and slide the guard into place over the disc, leaving about 1/4 of the disc exposed. Tighten the nut to secure the guard in place. Ensure it’s snug enough that the guard won’t shift during use.
Using the Angle Grinder
With a charged battery, grinding disc, and properly adjusted guard in place, you’re ready to use your cordless angle grinder. Grasp the handle firmly and place the grinder at a 45-degree angle against your workpiece. Squeeze the trigger to start the grinder spinning, and slowly apply pressure as you move it across the material using smooth, controlled strokes. Release the trigger to stop. Be very careful, as the disc and grinder will be extremely hot during and after use.
To keep your battery angle grinder in good working order, blow out the vents with compressed air to remove built-up dust and debris after each use. Check grinding discs for wear and cracks before each use and replace them as needed. With regular maintenance and care, your cordless angle grinder will serve you well for many projects to come.
Best Battery Angle Grinders FAQs
How long do the batteries last?
The runtime of battery angle grinders depends on the amp hour (Ah) rating of the battery. Higher Ah batteries, like 5.0Ah or higher, will typically last 30-45 minutes of continuous cutting or grinding. Lower Ah batteries may only last 15-30 minutes. The actual runtime also depends on the power draw of the grinder and the material you’re cutting. Harder metals require more power and reduce runtime.
How long do the batteries take to recharge?
Most battery angle grinders use lithium-ion batteries that can recharge in 30-60 minutes. However, for maximum battery life, it’s best to not discharge the battery fully before recharging. Look for grinders with fast charge times, around 30-45 minutes. Some higher-end models may offer dual charging ports so you can charge two batteries at once.
Are battery angle grinders as powerful as corded models?
Cordless angle grinders have come a long way in power and performance. Top battery-powered models now rival the power of mid-range corded grinders, with no cord to get in the way. High-output lithium-ion batteries and efficient brushless motors provide plenty of power for cutting and grinding metal, concrete, and stone. For professional, high-intensity use, a corded grinder may still have a slight power advantage. But for most DIYers and homeowners, a battery grinder will handle the job.
