Performance

• Durability: The semi-chisel tooth geometry is designed to withstand dry and dirty Australian hardwoods for sustained cutting.

• Battery Optimised: The .043" narrow-kerf profile removes less wood per pass, reducing load on the powerhead and extending runtime per charge on cordless units.

Makita EY403MP Chain Questions

What size chain does a Makita EY403MP take?

3/8" low profile pitch, .043" (1.1mm) gauge, 46 drive links on the standard 300mm (12") bar.

Is the EY403MP chain the same as the EY401MP?

No. The EY401MP runs a 10" bar with .050" gauge chain and 39 drive links. The EY403MP runs a 12" bar with thinner .043" chain and 46 drive links. They are not interchangeable — check which attachment you own.

What file do I use on this chain?

A 4.0mm (5/32") round file suits this 3/8" low profile chain.

Is this a genuine Makita chain?

No — it's an Alpine Chain Co. chain manufactured to the same specification, replacing the Makita 196740-7 and Oregon 90PX. Same pitch, gauge and drive link count, with a semi-chisel profile chosen for Australian hardwood. Every fit is backed by our Guaranteed Fit system.

How to Verify Your Chain Size

If you are unsure if this is the correct chain for your Makita EY403MP, check the side of your current guide bar. The Pitch, Gauge, and Drive Link (DL) count are typically stamped directly into the bar near the mounting bolts.
