Worth it for contractors who need corded-equivalent power without the cord. This 40V XGT saw delivers performance matching a 15 AMP corded model while adding AWS Bluetooth for automatic dust extraction and XGT digital communication that prevents battery damage. At 4.9 stars across 18 reviews, users praise its cutting speed and build quality.
Skip it if you’re already deep in Milwaukee M18 or DeWalt FlexVolt. Platform switching costs money. Both competitors offer flagship 7-1/4” saws with similar power — the real differentiator here is Makita’s AWS dust extraction system.
Power and Performance Specs That Matter
The sidewinder GSH01Z runs 6,000 RPM while the rear-handle GSR01Z hits 6,400 RPM. Both models cut 2-5/8” at 90° — deep enough for doubled-up 2x material in a single pass. That’s the same capacity as corded saws, which matters when you’re cutting rafters or rim joists.
| Specification | GSH01Z (Sidewinder) | GSR01Z (Rear Handle) |
|---|---|---|
| No-Load Speed | 6,000 RPM | 6,400 RPM |
| 90° Cut Capacity | 2-5/8” | 2-9/16” |
| 45° Cut Capacity | 1-13/16” | 1-3/4” |
| Max Bevel | 56° @ 1-5/16” | 53° @ 1-1/2” |
| Weight w/ Battery | 9.7 lbs | 11.7 lbs |
| Overall Length | 13” | 17-1/2” |
Automatic Torque Drive (ADT) adjusts speed and torque under load, which prevents the bog-down you get with lesser saws when hitting wet lumber or knots. The electric brake stops the blade quickly for safety and productivity. These aren’t marketing fluff — they translate to cleaner cuts and less waiting between cuts.
AWS Bluetooth and XGT Digital Technology
The Auto-start Wireless System (AWS) uses Bluetooth SIG certified communication to automatically start compatible dust extractors when you pull the trigger. No more walking back to flip the vacuum switch. No more forgetting to turn it on. Insert the optional wireless transmitter (198901-5) into the tool slot and pair it with your AWS-compatible vacuum.
This matters in Montana construction where silica dust regulations get enforced. Table saw stations already need dust collection — now your circular saw can tap into the same system. The AWS transmitter works across the Makita lineup, so one transmitter serves multiple tools.
XGT digital communication protects against overload, overdischarge, and overheating. The battery talks to the tool, monitoring current draw and temperature. Push too hard and it backs off power before damage occurs. Compatible with all XGT batteries from BL4025 (2.5Ah) up to BL4080 (8.0Ah). Bigger batteries mean longer runtime but also more weight on your wrist.
Build Quality and Weather Resistance
Die-cast magnesium base, blade guard, and blade cover keep weight down while maintaining rigidity. Magnesium costs more than plastic but won’t crack when dropped or flexed. Extreme Protection Technology (XPT) provides dust and water resistance for jobsite environments.
Dual LED lights illuminate the cut line — actually useful in dim garages or when cutting in shadow. The sidewinder model’s large 56° bevel capacity with positive stops handles steep-pitch roofing common in snow country. Adjust bevel using the front knob/lever with positive stops at common angles (22.5°, 45°).
Both models include a 24T carbide blade, wrench, and manual. Use on-board hex/offset wrench to change blades — standard 7-1/4” blades with 5/8” arbor. Depth adjustment uses a rear lever for cuts up to 2-5/8”.
Frequently Asked Questions
Q: How does the 40V XGT compare to 18V LXT for power?
The 40V platform delivers substantially more power. This saw matches the output of Makita’s 5377MG 15 AMP corded model. You’re not giving up cutting performance to go cordless. The trade-off is weight and battery cost.
Q: What’s the difference between the sidewinder and rear-handle models?
The GSH01Z sidewinder weighs 9.7 lbs and measures 13” long. The GSR01Z rear-handle weighs 11.7 lbs at 17-1/2” long. Framers typically prefer sidewinders for overhead work. Finish carpenters often like rear-handles for precision cuts. Both deliver identical power — it’s an ergonomics choice.
Q: Does AWS work with non-Makita dust extractors?
No. AWS requires Makita AWS-compatible vacuums and the 198901-5 wireless transmitter. The system uses proprietary Bluetooth communication. If you’re not buying into the Makita dust extraction ecosystem, the AWS feature becomes irrelevant.
Q: What warranty coverage do these saws carry?
Both tool and battery/charger carry Makita’s 3-year limited warranty. Register within 30 days for warranty activation. Keep your receipt — Makita requires proof of purchase for warranty claims.
Q: Can I use guide rails with these saws?
The GSH01Z sidewinder accepts Makita guide rails with an optional guide rail adapter. The rear-handle model compatibility isn’t specified in the available data. Guide rails matter for breaking down sheet goods accurately.
