I,m beginning to see why some of you guys use semi chisel .... This is the truth , to cut for 7 or 8 hours , burning 2 1/2 gal gas thru a 660 or 395 , and still have the chain sharp enough to where you consider leaving it on the bar over night , Instead of taking it home and grinding it is not at all uncommon . And an experienced cutter should be getting at least 5 hours ,1 1/2 -1 3/4 th gallon of gas before he needs to change a chain in Southeast, Alaska ....
.
. You will notice it sooner with full skip , then semi skip . and usually a full comp 3/8 will make it all day ....As long as a guy doesn,t get into the dirt and rocks bucking ................... Or the blastin crew didn,t shoot the timber full of rock puting in the roads ...... One driller / blaster gave me and 2 other guys a full 100' roll of chain because he over loaded a ditch line //......

... I am going to bring a few semi chisel chains with me the next time I go out to a camp ..

.
. I,ve been doing a test ,with the chain that came on my 353 Husky ... .325 Full comp semi chisel .... When I first looked at it I thot it would last one tree or less .. .. I have now cut around $ 2,400.00 worth of spruce and Silver Poplar with it ........... Bar is wearing out ... Chain is still about 50% ........ It doesn,t cut as fast as Chisel bit does , and properly ground or chisel filed chisel bit will smoke it for cutting speed ... .. But the fact remains that I,m making good money with that chain .. I,m very impressed ....... When the timber freezes it will be interesting to see how it does .... But in the hot and dry conditions we have had it has worked great .......
.
. Would I buy a roll of it , probably not , but I think I will try some Chisel bit ,325 ..
