5 Best Budget Angle Grinders under $100 – Reviews

1. DEWALT DWE402 – Top Pick

DEWALT DWE402

The versatile Dewalt DWE402 4-1/2″ Small Angle Grinder (“Dewalt DWE402”) is ideal for the budget-conscious user. Thanks to its many positive features and real-time operating benefits, this one earns our Top Pick label.

The DWE402 offers one of the best power to size ratios in its class, featuring an 11-amp AC/DC 11,000 rpm motor. It has a proprietary dust ejection system, oversized brushes for longer life, and numerous other durability features (e.g. a top mounted and protected spindle lock button, oversized threading).

You can choose the base grinder, a No Lock-On Paddle safety switch version, or the more robust grounded DWE402 for contractors. Each version includes the One-Touch Guard™ for 360-degree rotation and Quick-Change™ Wheel Release for easy wheel removal.

Regarding weaknesses, keep in mind that the Dewalt DWE402 is not meant for continuous, heavy-duty use. For example, if you’re looking for a welding grinder, please consider welding-ready grinders within the Dewalt family or other name brands.

As a high-performing budget grinder, your search can justifiably end here

Pros
  • Suitable for different types of cutting jobs.
  • Standard Dewalt warranty deal (3-years limited, 1-year free service).
  • Small gripping surface for optimal operating comfort.
  • Strong ergonomics, low operating vibration.
Cons
  • Switching occasionally a little rough.
  • Must approach Dewalt for specific cutting wheel guards.

2. Makita GA4030K – The Runner-up

Makita GA4030K

Makita’s GA4030K 4” Angle Grinder with Kit (“Makita GA4030K”) is a powerful contender in the economy-class category, offering top-quality functionality at a very low price point.

Fitted with a 6amp motor that delivers 11,000 RPM, the GA4030K’s ultra-small (2 ¼”) barrel grip is a category leader that you’ll appreciate. Its intricate construction, zigzag varnish, and thicker coil wires help extend tool life by preventing dust and debris entry. At 3.7 pounds, it won’t intimidate beginners or less-experienced DIYers.

Right out of the box, the Makita GA4030K comes with a grinding wheel, wheel guard, side handle, inner flange, lock nut, wrench, and a tool case (a bonus item).

Of the budget angle grinders under $100 reviewed here, the Makita GA4030K is the Dewalt DWE402’s closest competitor. In fact, it was almost our top choice. Why doesn’t it receive our highest recommendation? Well, switching isn’t always the smoothest, and extra effort is required to change the blade shield position.

Pros
  • Compact, lightweight with good power.
  • Electric cord made out of high-grade rubber.
  • Excels at wire-cutting, blade sharpening.
  • Adjustable for both left and right-handed use.
Cons
  • Lower amperage versus main competitors.
  • 4” grinding tool smaller than the 4.5” category standard.

3. Hitachi G12SR4 – Best for the Money

Hitachi G12SR4

The Hitachi G12SR4 6.2-Amp 4-1/2-Inch Angle Grinder (“Hitachi G12SR4”) earns the honor of being “Best for the Money” in the under $100 category. Leaving aside the really low price, it can give users the type of performance that almost makes cost an afterthought.

Coming with 5 depressed grinding wheels and a carrying case, it offers a 6.2. amp, 10,000 RPM motor that delivers 980 watts of maximum output power. Its small grip gives you more comfort and reduces fatigue during extended use. At 4.0 pounds with a slim gear case, the Hitachi G12SR4 allows users to negotiate tight areas for various cutting applications.

Hitachi is famous for aggressive pricing, so it’s easy to see why the G12SR4 is rated “Best for the Money” in our survey. However, its lack of power for some applications and the wheel guard’s iffy reliability prevent it from surpassing the above two choices.

Pros
  • Left-mounted slide switch with quick-off feature for safety.
  • Removable side handle for better control, for both right and left-handers.
  • Includes Wheel Guard, Side Handle, Spanner Wrench.
Cons
  • Slightly bulky.
  • Must purchase Dust Collection Attachment separately.

4. Bosch 1375A

Bosch 1375A

The Bosch 1375A 4-1/2” Angle Grinder (“Bosch 1375A”) merits some consideration as an economy choice. So, beyond price, what makes this particular Bosch grinder model stand out?

First off, its 6amp, 11,000 RPM (no-load) rated motor makes it well-suited for tough applications like metal fabrication, concrete restoration, and pipe fitting. A bevy of user-friendly features assures both comfort and control: the 1375A’s lightweight (3.75 pounds), lock-on slide switch, two-position side handle, and secure grip handle.

Unfortunately, the Bosch 1375A’s lack of power (680W) makes it a poor candidate for heavier use, and its California Proposition 65 warning will also deter potential customers who have many other choices. Also, with 14.4” L x 5.2” W x 5.2” H dimensions, this grinder is a bit heavier and bulkier than desired.

Pros
  • Epoxy-coated field windings help extends grinder life.
  • Two 4.5” abrasive grinding wheels included.
Cons
  • Newer power switch lock harder to operate.
  • Blue plastic casing not shatterproof.
  • Dust collection attachment doubles price if purchased separately.
  • Control button placement a bit awkward.

5. Jason’s Machine JM-6435

Jason’s Machine JM-6435

Founded in 1999, Jason Tools (a Chinese-based company) has entered the budget angle grinder market with its 4-1/2-inch Angle Grinder, the Jason’s Machine JM-6435.

On the surface, this grinder sports some interesting metrics. Powered by a 7.5 amp 11,000 RPM motor that produces a maximum of 900 watts, the base package includes a cutting wheel, an abrasive wheel, and a toolkit. Its short circuit protection stops the motor when problems occur. Its design—although boxier, with a cheaper looking handle—resembles that of its main competitors.

Apart from performance shortcomings (Zeroomade, the Amazon seller of Jason’s Machine JM-6435, recommends stopping the grinder at least once every 45 minutes), we question the support offered by both the manufacturer and Zeroomade. The Jason Tools website, not easily navigable, indicates that they’re not power tool specialists. Unfortunately, English correspondence is lacking, making us wonder about its North American support network when issues inevitably arise.

Pros
  • Streamlined design.
  • Basic purchase includes toolkit, wrench, side handle.
Cons
  • Too heavy (6 pounds).
  • Motor susceptible to frequent stoppages.
  • Lack of company history with power tools.
  • Where is the customer support?

Buyer’s Guide

Finding the best budget angle grinder under $100 demands still demands homework. Given that price range is limited, concentrate on other important criteria that can help you make the ultimate decision.

1. Unit size.

A bulky unit that doesn’t feel comfortable in your hands will bring you nothing but grief. The most reputable brand offerings tend to be well streamlined, weighing between 3 and 5 pounds.

2. Safety Features.

Safety should always be a major consideration when shopping for budget angle grinders. Most top competitors offer a bevy of safety features which include, but are not limited to, dust ejection systems, overcurrent circuit protection, and zero-voltage safety resets.

3. Disc Options.

Consider the disc’s thickness, historic wheel durability, and overall material make-up.

4. Grinder Disc Speed.

It’s important not to exceed the maximum speed rating (8-9,000 RPM) because discs can be easily stressed and warped, creating a safety hazard. At worst, they can crack, jeopardizing your safety and that of others on the shop floor.

5. Personal Comfort Level.

Can you easily turn the grinder on and off with a convenient paddle switch, even while wearing work gloves? Will you be forced to change and recharge batteries on a regular basis? How will it work in tight situations?
