How to choose the right grinder
Start with wheel size and mounting interface
Match the grinder to the diameter and mount of the discs you intend to use. A 5-inch wheel is not interchangeable with a 4-1/2-inch wheel simply because both are angle-grinder accessories. X-LOCK is a specific mounting system, not a universal interface: Makita explicitly limits the XAG26Z to X-LOCK accessories. Confirm the wheel, guard, and tool are approved for one another before use.
Factor in your battery platform and kit contents
If you already own compatible batteries and a charger, a bare tool may be practical; otherwise, include the cost of those items when comparing purchases. Bosch identifies the GWX18V-13CN as a bare tool, and Makita says the XAG26Z’s battery and charger are sold separately. Verify what comes in the exact retailer configuration, since model suffixes and kit contents can differ.
Choose controls for the task
The listed models differ in switch style and speed control. Bosch’s GWX18V-13CN has a slide switch; Makita’s XAG26Z and XAG11Z have paddle switches, and the XAG20Z adds a variable-speed dial. The XAG04Z and XAG11Z list Automatic Speed Change. These distinctions may help narrow a choice, but the specifications alone do not establish which grinder removes material faster or feels better in hand.
Recommended Free Tools
#1 Best Overall
- Brushless motor of the angle grinder requires no brush changes.
- DEWALT grinder's brake stops wheel in 2 seconds or less on average
- Kickback Brake engages when a pinch, stall, or bind-up event is sensed and the electronic brake engages with maximum force to quickly stop the wheel, reduce the movement of the metal grinder and shut the grinder off.
- Features E-Switch Protection - When the ON/OFF trigger switch has a no-volt release function. In the event of a power outage or other unexpected shut down, the trigger switch will need to be cycled (turned off and then on) to restart tool.
- Two stage trigger requires two actions to activate tool.
Match the model and wheel to the material
Makita describes the XAG04Z for grinding, cutting, and sanding materials such as tile, concrete, pipe, and conduit. That is an application description, not permission to use any wheel on any material: select an accessory rated for the task and material, and follow the tool manual for allowed accessories, guards, and operation.
What the specifications do—and do not—tell you
“18V” identifies a battery platform, not a measure of grinding capacity. Bosch lists 9,000 no-load RPM and a 5–6-inch wheel range for the GWX18V-13CN; Makita lists 8,500 RPM and a 5-inch wheel for the XAG26Z. No-load speed figures do not establish performance under load, runtime, or job speed, and RPM alone is not a sound basis for ranking these tools.
Rank #2
- Run Time - Up to 56 cuts of 1/2" rebar**
- Perform & Protect - This grinder is equipped with ANTI-ROTATION features including a Kickback Brake and E-Clutch.

- Ergonomic & Lightweight - This grinder is light weight, 3.55 LBs (Bare Tool) to help prevent fatigue.
Safety-related features also vary. Bosch lists KickBack Control, Electronic Clutch Control, restart protection, and X-Brake for the GWX18V-13CN; Makita lists AFT, electric braking, and bind-up control for the XAG26Z. These are manufacturer-stated features, not guarantees against injury. Use the correct guard and accessories, inspect them before use, and follow the manual and safe operating practices.

Limits of the comparison
The cited US manufacturer pages establish listed specifications and features, not independent rankings. They do not establish current street prices, stock, durability, runtime under load, or comparative grinding performance. Treat the named tools as models to compare, and check current status and the exact listing before buying.
