The Makita XAG17ZU is an 18V LXT brushless 4-1/2 in. / 5 in. variable speed cut-off/angle grinder with an electric brake and AWS (Auto-Start Wireless System). AWS uses Bluetooth to automatically start a compatible Makita dust extractor when the grinder is triggered and stop it when the grinder stops, keeping the work area clean without manual intervention. Variable speed (3,000 to 8,500 RPM) and Electronic Torque Control round out a safety- and dust-conscious feature set. Tool only — battery and charger sold separately.
How does AWS work on the XAG17ZU?
AWS (Auto-Start Wireless System) uses a built-in Bluetooth transmitter in the grinder to communicate with a compatible Makita dust extractor. When you pull the trigger, the grinder sends a wireless signal to start the extractor automatically. When you release the trigger, it signals the extractor to stop. This eliminates the need to manually switch dust collection on and off, keeping silica and concrete dust contained at the source.
Does the XAG17ZU require a compatible Makita dust extractor to work?
No. The XAG17ZU operates fully as a standalone grinder without any dust extractor. AWS functionality is an optional add-on — if you own a compatible Makita AWS-enabled dust extractor, the wireless pairing activates automatically. Without one, the grinder functions identically to the XAG16Z.
What dust extractors are compatible with the XAG17ZU's AWS system?
Makita's AWS-compatible vacuums include models in the VC series (e.g., VC4710, VC2500) with the AWS receiver module installed, and some cordless LXT vacuums. Check Makita's current compatibility chart or look for the AWS symbol on the extractor's packaging.
Does the XAG17ZU use a slide switch or paddle switch?
The XAG17ZU uses a slide switch with lock-on for sustained operation. If you need a paddle switch (no lock-on, dead-man style), consider the XAG21ZU, which pairs paddle-switch safety with AWS and an electric brake.
Can I use the variable speed on the XAG17ZU for grinding mortar joints?
Yes, the variable speed down to 3,000 RPM is useful for controlled mortar removal with a tuckpointing blade, allowing better speed matching for the blade type and material. A slower speed also reduces the risk of damaging surrounding brick faces.
