I love Treestuff.com, but sometimes the product information can be confusing. Here is a sizing guide from the manufacturers website. ATTN TREESTUFF: can you guys add this guide to the product info for the sharpener and carbides. I got the wrong carbide because the previous descriptions were confusing, this one is updated within the last week.

One sharpener is compatible with all five carbide sizes.
The carbide size required is determined by the chain pitch which is usually labeled on the chain saw bar near the motor and sometimes imprinted on the chain itself. This number will be .404, 3/8, .325, 3/8P, or 1/4.
3/8″ and .404″ pitch chain = Large 7/32″
3/8″ pitch chain = Large 7/32″
“Stihl” brand 3/8″ pitch chain = Large 13/64″
.325″ pitch chain = Medium 3/16″
3/8″ Low Profile (LP, Picco, micro, mini) = Small 5/32″
1/4″ pitch chain = Extra Small 1/8″
Inches = mm
7/32″ = 5.5 mm
13/64″ = 5.1 mm
3/16″ = 4.8 mm
5/32″ = 4.0 mm
1/8″ = 3.2 mm
A Note About the Large 3/8 pitch
This is where people usually get confused. If you have the large 3/8” pitch chain you will need the 7/32” carbide cutter. UNLESS the brand of that large 3/8” pitch chain is Stihl. For whatever reason Stihl makes their large 3/8” pitch chains slightly smaller than the rest of the industry (we are talking slight, as in 1/64”). This is why the manufacture recommends the 13/64” size file.
For all other size pitch’s (Stihl, Oregon etc) it doesn’t matter what brand the chain is. So a .404 pitch chain it will always be 7/32 carbide cutter. The .325 pitch chain will always be a 3/16” carbide cutter. The smaller 3/8”P pitch (Picco or micro or LP =Low Profile) will still be a 5/32. The 1/4 pitch will still be the 1/8 carbide cutter.
