Chains of the same size and type should be the same right? Well, every manufacture has a different idea's about what works best, and we end up with a variety of different chain sizes and shapes in the same pitch / guage.
This is why people are brand loyal. All those chains will fit and work but some cut better while others stay sharp longer. I never paid any attention to husky 3/8 semi chisel, but I may try some, it's not that rounded so it's likely faster than other semi chisels.
That's what I'm thinking as well but want to try them for a while to find out. It is very similar in shape to some of Oregon's micro chisel chains but, for reasons I don't understand, Oregon doesn't offer a micro in 3/8. They do in 325 and 404
Which part, the LP being different or the different semi shapes? 3/8LP is strange with the sizes changing in the same gauge as well as with when changing the gauge. The numbering system for it makes no sense to me either. Add to that the "L" in VXL is for long, but it's kind of short compared to others. It's a complicated size
I don't think so. I have always stressed that each type of chain has to be treated individually. They can have different geometries, different kerf widths and so on. That is why, for example, one file size does not always have to be recommended for a given chain size, understood as a pitch and whether it is a low profile type chain. For example, for 90 PX, which is described by Oregon as a narrow kerf, has a pitch of 3/8, a 1.1 mm gauge and is of the low-profile type, a 4.5 mm file is recommended instead of the usual 4 mm for 3/8 LP chains. This does not change the fact that the cutters of "normal" 3/8 or .325 Stihl or Oregon chains are the same. Because they are the same "type", whereas they will differ in the thickness of the drive link to work with different types of guide bars.
