Buying Guide: Motor Power, Included Accessories, Build Quality and Budget
How much motor power do you really need?
The biggest difference between the models here is amperage. The lineup spans from 6.2 amps (Metabo HPT) to 10 amps (the 10 Amp model). A higher amperage means the motor can maintain speed when you lean into the cut.
For light tasks like sharpening blades or cutting thin sheet metal, a 6-amp grinder works fine. For cutting rebar or heavy steel plate, the 10-amp motor is worth the extra weight. The DEWALT sits in the middle at 7 amps, which is adequate for most general tasks if you pair it with sharp wheels.
If you're the kind of person who keeps a spare wheel handy and works methodically, any of these will do. But if you often grind for extended periods without letting the tool rest, consider the 10-amp model.
What's included in the box matters
One of the biggest differences between these grinders is what you get besides the tool itself. The AVID POWER 7.5A includes a grinding wheel, a cutting wheel, a flap disc, and a side handle. The Metabo HPT includes five grinding wheels and a hard case.
The budget AVID POWER 750W includes a wheel, a cutting disc, and even a pair of gloves. The 10-amp model and the DEWALT include nothing but the tool and a side handle. If you don't already have a stash of wheels and a storage solution, the Metabo HPT or the full AVID POWER kit save you an extra trip to the hardware store.
Compare what you'd spend on a case and a pack of wheels before deciding.
Build quality and long-term durability
The DEWALT DWE4011 is the clear winner for toughness. Its glass-filled nylon housing and sealed switch are designed for daily abuse. The Metabo HPT also uses quality materials from a respected brand.
The two AVID POWER models and the 10-amp grinder are more budget-oriented plastic constructions. They'll survive normal home use, but a drop from a workbench onto concrete might crack the housing on the cheaper models. For a shop that sees heavy use, spending a bit more on the DEWALT or Metabo HPT is an investment in longevity.
If you're a weekend warrior, the AVID models offer excellent value. Remember to consider routine maintenance: keep the air vents clean and occasionally check the brushes on the brushed-motor models.
Making the final call on budget
The price spread across these five models is modest, but the value equation changes based on your needs. The budget-friendly AVID 750W gets you a functional grinder at the lowest entry point. The AVID 7.5A adds more power and useful accessories for a small step up.
The Metabo HPT adds a hard case and brand cachet. The DEWALT is the premium pick for build quality. The 10-amp model is the specialist for raw power.
Think about how often you'll use it and for what material. For odd jobs around the house, the budget options are fine. For regular metal fabrication, jump to the DEWALT or the 10-amp.

Who Should NOT Buy Best Angle Grinder under 100
This category is the wrong purchase for three kinds of buyers. Here's who they are, and what to look at instead.
You Need a Cordless Grinder for Portability
If you work on a roof, a remote job site, or anywhere without a power outlet, a corded grinder is a leash you don't want. These models all require a 120V AC outlet and an extension cord. Look at cordless 4-1/2 inch grinders from DEWALT, Milwaukee, or Makita that run on their respective battery platforms.
They cost more upfront because you need batteries and chargers, but the freedom of movement is worth it for mobile work.
You Need to Cut Thick Concrete or Tile
A 4-1/2 inch grinder with a standard wheel is not the best tool for cutting deep into concrete slabs or thick stone. The wheel size limits the depth of cut to about 1 inch with a standard blade. For concrete cutting, consider a 7-inch or 9-inch grinder, or a dedicated concrete saw.
For tile, a wet tile saw gives cleaner cuts. These angle grinders are best for metal and light masonry work with a diamond blade.
You Need a Variable Speed Grinder for Polishing
None of the models in this roundup have variable speed control. They all run at a fixed 10,000 to 11,500 RPM. If you want to polish stainless steel or work with paint removal using a soft pad, a fixed speed grinder can be too aggressive.
A variable speed model (often with a dial on the back) lets you slow down for polishing and speed up for cutting. Brands like Bosch and Makita offer variable speed grinders for a higher price.
Final Verdict
The DEWALT DWE4011 takes the top spot for best overall build quality and the One-Touch guard that actually saves time. If you want the best value with accessories included, the AVID POWER 7.5A gives you everything you need at a fair price.
Need the most raw cutting power for heavy steel? The 10 Amp Angle Grinder has the strongest motor. Want a hard case and a trusted brand name?
The Metabo HPT covers that niche nicely.
If none of these fit your needs, check the Who Should NOT Buy section above before spending anything. The right tool depends on your specific work style.
FAQ
What's the best Angle Grinder under 100 overall?
The DEWALT DWE4011 is the best overall option for its build quality and one-touch guard. If you want included accessories, the AVID POWER 7.5A is a close alternative.
Can I use these grinders for cutting tile?
Yes, with a diamond blade. But the 4-1/2 inch size limits depth to about 1 inch. For large tiles, a wet saw or larger grinder is preferable.
How do I change the wheel on an angle grinder?
Unplug the tool. Press the spindle lock button to hold the shaft. Use the wrench to loosen the flange nut.
Remove the old wheel, place the new one, and tighten the nut. Never overtighten.
Are these grinders suitable for removing rust?
Yes. Use a wire cup brush or a flap disc for rust removal. The AVID POWER 7.5A includes a flap disc, making it the best starter for this job.
Do I need to use a side handle?
Yes, always. Angle grinders can kick back with significant force. The side handle gives you a second point of control and reduces the risk of losing grip.
What safety gear should I use with an angle grinder?
Always wear safety glasses, a face shield, heavy gloves, and a dust mask. Hearing protection is also recommended. Never remove the guard.
