The Makita XAG16Z is an 18V LXT brushless 4-1/2 in. / 5 in. cut-off/angle grinder with variable speed (3,000 to 8,500 RPM), an electric brake, and Electronic Torque Control. The variable speed dial lets you match wheel speed to the material — lower speeds for polishing or aggressive cutting of softer material, maximum speed for hard metal grinding. The electric brake stops the wheel in 2 seconds or less and Electronic Torque Control cuts motor power if the wheel is suddenly forced to stop. Tool only — battery and charger sold separately.
What is the benefit of variable speed on the XAG16Z?
Variable speed (3,000 to 8,500 RPM) lets you match wheel speed to the application. Lower speeds are useful for polishing with flap discs, working with certain plastics or wood, or using slower-rated specialty abrasives. Full 8,500 RPM is ideal for aggressive metal grinding. Without variable speed, you are always running at maximum, which can burn softer materials or degrade certain abrasive types.
What is Electronic Torque Control on the XAG16Z?
Electronic Torque Control (ETC) monitors motor load in real time and cuts power if the wheel is suddenly and forcibly stopped — a situation that can cause dangerous kickback. It works in tandem with the electric brake and provides an additional layer of protection beyond the brake alone.
How does the XAG16Z compare to the XAG09Z?
Both are 18V LXT brushless grinders with electric brakes and a slide switch. The XAG16Z adds variable speed control and Electronic Torque Control, giving it more versatility across different materials and a higher safety profile. The XAG09Z runs at a fixed 8,500 RPM.
Is the XAG16Z suitable for polishing or finishing work?
Yes, the variable speed range down to 3,000 RPM makes the XAG16Z appropriate for polishing and light finishing tasks when fitted with polishing pads or fine-grit flap discs. Always confirm the accessory's minimum RPM rating is compatible with your chosen speed setting.
What is the difference between the XAG16Z and XAG17ZU?
Both share the same variable speed brushless motor and electric brake. The XAG17ZU adds AWS (Auto-Start Wireless System), which wirelessly activates a compatible Makita dust extractor via Bluetooth when the grinder is triggered. If dust management is a priority, the XAG17ZU is the upgrade.
