Milwaukee chainsaw sharpening

[Fred Werring]

Got a Milwaukee M18 chainsaw, need to sharpen the chain

Size 90 chain...charts I've found say use a 4.5mm file/stone

Dremel (and other places) says to use a 4mm on a 3/8 low profile chain.

So what are you guys with Milwaukees using...4 or 4.5mm?

4mm is a lot easier to come by....

A 5/32 is really close, close enough for hand filing.

I'm thinking Dremel tool...I should have been clear what I wanted to use.

If you look closely at the teeth, the tops slope back. The first sharpening would then need a 4.5mm and as you sharpen the teeth, they will get shorter and you would then change to a 4mm file. Or maybe not, I use a single size of file and when the file is cutting too far into the chain links, I replace the chain.

The Milwaukee M18 chainsaw Owner's Manual says to use a 5/32 round file. However, a replacement Oregon R56 chain lists 4.5mm as the proper size.
