Best Budget
Porter-Cable Angle Grinder
Pros
- Lightweight design
- Good max speed
- Three handle positions
Cons
- Lacks some safety features
With its 7.5-amp output, Porter Cable’s 4.5-inch angle grinder is a greater light duty corded option. It produces 10,000 RPM, ample power for cutting through masonry or metal pipe, as well as other projects around the house. It also has three different handle positions that make it easier to hold at a variety of angles.
At just 3.5 pounds, it’s one of the lighter angle grinders you’ll find. It lacks some of the additional features you’ll find on other angle grinders, such as auto-shutoff and a fast brake, but it also costs about half the price of angle grinders with those bells and whistles.

Best Cordless
Kobalt 5-inch 24-volt Cordless Angle Grinder
Pros
- Ample power with 24-volt brushless motor
- Multiple handle positions with paddle style trigger
- Comes with six starter blades
Cons
- No overload protection
Kobalt, the in-house tool brand for Lowe’s, has made a name for itself by packing tremendous power into its cordless power tools. Where other cordless angle grinders have 18-volt motors, Kobalt puts a 24-volt brushless motor in its angle grinder. The result produces loads of power to the tune of 8,500 RPM with a large 5-inch wheel.
The Kobalt angle grinder comes with a long paddle trigger for increased safety and an auxiliary handle that’s mountable in multiple places and easy to operate. You also get six blades in this kit, a far larger set of starter wheels than most offer. It’s a powerful cordless angle grinder at a surprisingly affordable price.

Best Value
Craftsman 4.5-in 7.5 amps Corded Angle Grinder
Pros
- Affordably priced
- High top speed
Cons
- No auto cut-off
If you only need to occasionally sharpen a blade, there’s no need to spend hundreds on a top of the line angle grinder. This 4.5-inch corded model offers ample power at a much lower price point. With its 7.5-amp motor, it reaches speeds of up to 12,000 RPM, plenty of juice for any angle-grinding job. Its paddle-style switch cuts off the blade should you lose your grip on it. Change its wheel in a flash thanks to its tool-free wheel adjustment.
The Craftsman lacks overload protection, a feature you’ll find on pricier angle grinders. That said, if you only need an angle grinder every so often, this value option gets the job done.

Best Compact
Bosch 3-in 12-volt Brushless Cordless Angle Grinder
Pros
- Fits easily into tight spots
- High blade speed of 19,500 RPM
- Lightweight design
Cons
- Limited cutting depth
This compact cordless Bosch angle grinder cuts quickly and cleanly through tile or pipes located in spots that are too tight for a full-sized model. At just 3 inches long and weighing only a pound and half without a battery, you can wield it one-handed and comfortably fit it into tight spots.
While its cutting depth is limited by its 3-inch blade, it cuts through most tiles. The small blade coupled with a brushless motor also produces a high max speed of 19,500 RPM, so it cuts very quickly. Bosch’s 3-inch angle grinder also comes with several built-in safety features, including overload protection, fast braking, and restart protection.
