Makita M0900B 540W Angle Grinder is a compact 100 mm grinder running at 12,000 RPM, designed by Makita specifically for light-duty applications — deburring, rust and weld cleanup, small cuts in steel section, and occasional tile or masonry work with the right wheel.

It's worth being straight about where this sits. At 540 W it is not a site-duty grinder for continuous heavy cutting; it's the tool you reach for when a job needs a grinder for twenty minutes, and its 1.6 kg weight makes that far more comfortable than wrestling a 900 W machine. Used within that brief it's a genuinely good tool, and Makita build quality shows in how it holds speed and how long the bearings last.

The two-action safety switch is a real safety feature rather than a marketing line: it requires a deliberate two-step movement to engage, so the grinder can't lock on accidentally if it's knocked or set down carelessly. A shaft lock makes wheel changes quick, and the wheel cover is designed to protect the operator with minimal movement.

Technical Specifications

Usage and Safety Guidelines

Recommended Applications

1) Is this grinder suitable for heavy daily site use?

Makita rates it for light-duty applications, and we'd rather say so than oversell it. It's excellent for intermittent grinding, deburring, and occasional cutting. For continuous heavy cutting through the working day, choose a higher-wattage grinder built for that duty cycle.

2) What wheels can I use with it?

Any 100 mm (4") wheel rated for 12,000 RPM or higher — grinding discs, cutting discs, flap discs, and wire cups. Never fit a wheel with a lower speed rating than the tool.

3) Can it cut tiles and masonry?

Yes, with the correct diamond blade. For chip-free tile edges use a continuous-rim blade; for concrete and brick a segmented blade clears heat better. Always wear an N95 mask — dry cutting masonry releases silica dust.

4) What is the "two action safety switch"?

The switch requires a deliberate two-step movement to engage, so the grinder cannot accidentally lock on if it's knocked or put down carelessly. It's a meaningful safety feature on a tool that spins at 12,000 RPM.

5) Does it come with a grinding wheel?

Standard accessories are the side grip and lock nut wrench. Wheels are normally purchased separately so you can match the disc to your material — check the listing's box contents before ordering.
