Makita XAG17Z 18V X2 LXT Grinder
Best OverallPros
- Near-corded power from dual batteries
- Soft start and anti-restart protection
- Accepts 5-inch wheels for deeper cuts
Cons
- Heavier than single-battery models
- Requires two batteries and charger (sold separately)
The XAG17Z uses two 18V batteries in series to deliver 36V of power. Owner reviews consistently note it stalls less on thick steel than single-battery grinders. The 5-inch wheel gives more cutting depth than standard 4-1/2-inch models, which is useful for pipe and rebar work.
The soft start feature reduces torque reaction when pulling the trigger. The anti-restart function prevents the wheel from spinning if the battery is reconnected while the switch is on. Some users report the tool feels nose-heavy with two batteries, but the added weight also reduces vibration during prolonged use.
Makita 9557PB 4-1/2-Inch Angle Grinder
Best CordedPros
- Strong 7.5A motor for continuous use
- Labyrinth construction seals motor from dust
- Compact and lightweight for its power
Cons
- No variable speed control
- Power cord can be stiff in cold weather
The 9557PB is a workhorse corded grinder that has been a favorite among metalworkers for years. The 7.5A motor maintains speed under load better than lower-amp models. The labyrinth construction uses a sealed bearing and felt ring to keep debris out of the motor housing, which extends brush life.
Owner reviews highlight the paddle switch design as easy to use with gloved hands. The tool weighs only 4.4 pounds, reducing fatigue during extended grinding sessions. The main drawback is the lack of variable speed, which means it is less suited for polishing or working on softer materials like aluminum.
Makita GA4530 4-1/2-Inch Angle Grinder
Best Budget CordedPros
- Very affordable price point
- Lightweight at 4.0 lb
- Durable aluminum gear housing
Cons
- Lower 6.0A motor stalls easier under heavy load
- Slide switch can be bumped off accidentally
The GA4530 is Makita's entry-level corded grinder. It uses a 6.0A motor that handles light grinding and cutting tasks well but bogs down on thick steel or prolonged use. The aluminum gear housing helps dissipate heat, which improves durability compared to plastic-housing budget models.
Owner reviews mention the tool runs smoothly and the spindle lock works reliably for wheel changes. The main complaint is the slide switch design, which some users find less secure than a paddle switch. For DIYers and occasional use, the GA4530 offers good value without sacrificing build quality.
Makita XAG04Z 18V LXT Grinder
Best Compact CordlessPros
- Very lightweight and compact
- Slide switch with lock-on for continuous use
- Battery fuel gauge on tool
Cons
- Less torque than X2 models
- Battery and charger sold separately
The XAG04Z is Makita's smallest 18V grinder. It weighs just 3.9 pounds with a 5.0Ah battery, making it easy to maneuver in tight spaces or overhead work. The 8,500 RPM no-load speed is lower than corded models, but the brushless motor delivers consistent power through the cut.
Owner reviews praise the tool's balance and low vibration. The lock-on slide switch is convenient for extended grinding, though some users prefer a paddle switch for safety. The main limitation is battery runtime; a 5.0Ah battery provides about 15-20 minutes of heavy grinding. It works best for quick cuts and light surface prep.
Makita DGA452Z 18V LXT Grinder
Best Versatile CordlessPros
- Brushless motor for longer runtime
- Variable speed dial (3,000-8,500 RPM)
- Anti-restart protection standard
Cons
- Slightly heavier than XAG04Z
- Speed dial can be bumped during use
The DGA452Z adds variable speed control to Makita's 18V platform. The speed dial lets you reduce RPM for polishing or working on stainless steel without burning the surface. The brushless motor improves runtime by about 30% compared to brushed models, according to Makita's published specs.
Owner reviews note the tool handles well and the variable speed is genuinely useful for detail work. The anti-restart feature is a welcome safety addition. Some users report the speed dial knob is exposed and can shift if the grinder is set down roughly. It is a solid all-rounder for users who need one grinder for multiple tasks.
What to Check Before Buying a Makita Angle Grinder
Power source. Corded grinders offer unlimited runtime and higher torque for heavy work. Cordless models provide portability but require battery investment. Choose based on your access to outlets and typical job duration.
Wheel size. 4-1/2-inch wheels are standard and fit most tasks. 5-inch wheels (like on the XAG17Z) provide deeper cutting capacity but limit compatibility with some guards and accessories.
Motor type. Brushless motors run longer per charge and last longer than brushed motors. Corded brushed motors are cheaper to repair but produce more sparking and dust ingress.
Switch style. Paddle switches require constant pressure for safety. Slide switches with lock-on reduce hand fatigue but increase risk if dropped. Choose based on your comfort with safety trade-offs.
Speed control. Variable speed is essential for polishing and working on heat-sensitive materials. Fixed-speed models are simpler and more durable for grinding only.
Mistakes to Avoid When Buying an Angle Grinder
Buying too much power for light use. A 15A corded grinder is overkill for occasional DIY use. It adds weight and cost without benefit for light grinding.
Ignoring battery compatibility. Makita uses the 18V LXT platform across most cordless tools. If you already own Makita batteries, buy a bare tool to save money. If you are starting fresh, factor in battery and charger costs.
Choosing a grinder without safety features. Anti-restart protection and soft start reduce injury risk. These features are standard on newer models but missing on older budget units.
Forgetting wheel availability. 4-1/2-inch wheels are the most common and cheapest. 5-inch and 6-inch wheels cost more and have fewer options at local hardware stores.
