The Makita XAG04Z is an 18V LXT brushless 4-1/2 in. / 5 in. cut-off/angle grinder delivering 8,500 no-load RPM for fast cutting and grinding of tile, concrete, pipe, and conduit. The Makita-built brushless motor provides up to 50% longer run time versus brushed models and eliminates carbon brushes for extended service life. Automatic Speed Change technology continuously adjusts motor speed and torque during use for optimal performance. Slide switch with lock-on for convenient operation; tool only — battery and charger sold separately.
What is the difference between the XAG03Z and XAG04Z?
The XAG04Z is the successor to the XAG03Z. The main upgrade is 5 in. disc compatibility in addition to 4-1/2 in., giving you more accessory options. Both use the same 18V LXT battery platform and brushless motor technology.
Does the XAG04Z have an electric brake?
No, the XAG04Z does not include an electric brake. The wheel coasts to a stop when the switch is released. If an electric brake is important for your work, consider the XAG09Z, which adds an electric brake that stops the wheel in 2 seconds or less.
Which batteries work with the XAG04Z?
Any Makita 18V LXT slide-style battery with the Star symbol is compatible. Common choices include the BL1850B (5.0Ah) for maximum run time and the BL1830B (3.0Ah) for lighter weight. The XAG04T kit version bundles two BL1850B batteries and a rapid charger.
Can I use this grinder for tile cutting?
Yes, the XAG04Z is well-suited for tile cutting with an appropriate diamond blade. Use a blade rated for the material — porcelain requires a premium diamond blade while standard ceramic tolerates an economy option. Always use the appropriate guard and personal protective equipment.
Is the XAG04Z's 8,500 RPM good for metal grinding?
Yes, 8,500 RPM is a standard high-speed rating for 4-1/2 in. / 5 in. angle grinders and is well within spec for Type 27 grinding wheels rated for 12,000+ RPM. Automatic Speed Change technology also adjusts torque under load, maintaining consistent wheel speed when cutting through tough material.
