The Makita XSH05ZB is the AWS-capable version of the 18V LXT sub-compact brushless 6-1/2 in. circular saw. When paired with the optional AWS transmitter (No. 198901-5), it uses Bluetooth to wirelessly trigger an AWS-equipped Makita dust extractor automatically when the saw starts and stops. All other specs match the XSH04ZB: 5,000 RPM, 2-1/4 in. cutting depth at 90°, 10-5/8 in. length, and 6.4 lbs. with battery.
What does AWS mean on the XSH05ZB?
AWS stands for Auto-Start Wireless System. When the optional AWS transmitter (No. 198901-5, sold separately) is installed and paired with a compatible Makita dust extractor, the extractor automatically starts and stops when the saw starts and stops — no manual switching required. This keeps the dust extractor running only when needed and reduces airborne fine dust.
Do I need the AWS transmitter to use the XSH05ZB?
No. The XSH05ZB is fully functional as a circular saw without the AWS transmitter. AWS capability is an add-on feature for users who want wireless dust extractor integration. The saw operates identically to the XSH04ZB without the transmitter.
Is the XSH05ZB brushless?
Yes. The Makita BL brushless motor eliminates carbon brushes for up to 50% longer run time and extended tool life versus brushed motors. The motor also runs cooler, which contributes to consistent performance on high-volume cutting tasks.
What battery should I pair with XSH05ZB for a full workday?
For all-day framing or roofing, pair the XSH05ZB with two 5.0Ah or 6.0Ah batteries and swap them alternately with a DC18RC charger. In testing, the sub-compact motor made up to 174 cross-cuts per charge on 2×4 SPF with a 5.0Ah battery.
How does XSH05ZB differ from XSH04ZB?
The XSH05ZB adds an AWS receiver on the saw body so it can communicate with a compatible Makita dust extractor via Bluetooth. Motor, blade size, RPM, cutting depth, bevel range, and weight are identical to XSH04ZB.
