Makita XAG20Z vs XAG16Z Comparison
Weight and Portability
The Makita XAG20Z weighs 7.1 pounds, while the Makita XAG16Z is lighter at 6.85 pounds. Both tools share identical dimensions of 13.9 inches in width, 5.4 inches in height, and 7.9 inches in length. This means the overall footprint is the same for both models. However, the half-pound difference in the XAG16Z can matter during extended overhead work or when you are holding the grinder for long periods. The lighter build of the XAG16Z reduces fatigue slightly. If you prioritize a lighter tool for repetitive tasks, the XAG16Z has a clear advantage here.
Switch Type
The Makita XAG20Z features a paddle switch, which is a distinct operational choice. The data for the Makita XAG16Z does not explicitly list its switch type, though it shares the same motor and safety systems. Paddle switches often allow for easier one-handed operation or quick engagement without moving your hand to a trigger. This design choice on the XAG20Z may suit users who prefer that specific control layout. Without explicit data on the XAG16Z switch, we cannot confirm if it uses a paddle or a traditional trigger. The XAG20Z offers a specific ergonomic feature that is clearly documented.
Motor and Power
Both the Makita XAG20Z and the Makita XAG16Z utilize an 18V LXT BL brushless motor. They share the same variable speed dial, allowing manual RPM adjustment from 3,000 to 8,500. Both include electric brakes that stop the wheel in two seconds or less. They also both feature Active Feedback-sensing Technology (AFT) and automatic speed change technology. Since the motor type, voltage, and advanced electronic features are identical, there is no performance difference in cutting or grinding power. You get the same efficiency and cooling benefits from either model.
Wheel Compatibility
Both grinders are designed to accept 4-1/2-inch and 5-inch wheels. This dual compatibility gives you flexibility in choosing abrasive discs or cut-off wheels. The specifications for wheel diameter are identical for both the XAG20Z and the XAG16Z. This means you can use the same consumables for either tool. There is no advantage in terms of accessory variety or compatibility. Both models support the standard sizes for this class of angle grinder. Your choice of wheels will not be limited by the model you select.
Included Tools and Battery
The Makita XAG20Z is listed as a bare tool, meaning it includes only the grinder without a battery. The data for the Makita XAG16Z does not explicitly state the battery inclusion status, but it is also marketed as a bare tool in its standard configuration. Both are sold as single units of the grinder. Neither listing indicates the inclusion of a carrying case or additional accessories in the base package. Since both are essentially the same tool with minimal packaging differences, there is no significant advantage in what is included in the box for either model.

Users needing paddle switch control
The XAG20Z features a paddle switch. This design allows you to engage the tool only while pressing the switch. If you release the paddle, the motor stops immediately. This offers precise control for detailed work. The XAG16Z lacks this specific switch type in the provided data, making the XAG20Z the better choice for operators who prefer this safety and control method.
Those prioritizing lighter weight
The XAG16Z weighs 6.85 pounds. This is 0.25 pounds lighter than the XAG20Z. Over long periods of overhead use or extended shifts, this weight difference reduces fatigue. Both tools share the same dimensions and brushless motor technology. If minimizing physical strain is your priority, the lighter XAG16Z provides the same performance with less mass to support during operation.
General users wanting standard features
The XAG16Z includes all core performance specs. It has a brushless motor for efficiency and longer life. It offers variable speed control from 3,000 to 8,500 RPM. The electric brake stops the wheel in two seconds or less. It supports 4-1/2-inch and 5-inch wheels. For most users, these essential features are sufficient without the need for the paddle switch found on the other model.
