We have an essential info section looking at how to ID chains – why not take a look by clicking here.

Chains are not measured by stretching them out on a bench and squinting down a tape measure – chains are identified by PITCH, GUAGE and NUMBER OF DRIVE LINKS [no – not the cutting teeth – drive links and you’ll know the difference by even a cursory look at the chain ID link above].

Bars likewise are not measured the same way – manufacturers give them a set ‘length’ which is generally the sticky out bit that comes out of the chainsaw [not including the mount unless in the case of large double ended milling bars which are the exception to the rule and measured end to end].

Chain sharpening is key – if you cannot use a chain and have it cutting well until the cutters are so small they end up getting knocked off – you have plenty to learn. Watch, research, rinse and repeat. Read our article on chain sharpening by clicking here – often people get caught up in different angles and techniques – but the principles are always the same.

If you are serious about correct maintenance of your bar and chain work your way through the Oregon manual [click here] and after that check out the Stihl equivalent [click here]. Using a chainsaw for 20 years [badly] does not qualify you as an experienced user – so be the change, make the difference and keep educating yourself about these valuable yet dangerous tools.

And finally – why buy a new bar and chain without checking/replacing the drive rim or drive sprocket? [again click here if unsure on what these refer to]. Would you change the oil on your car without changing the oil filter?

Oregon lo pro ripping chain – good option and some people prefer it to the Stihl PMX – also a better price. Shorter cutters give less resistance – better priced than the Stihl PMX.

Ripping chain value.

Chain cuts fine.
Interestingly though - the tooth length, as new is, noticeably shorter than the Stihl ripping chain I have which has had several tickles with the Granberg grinder.
So although cheaper per link it might not be better value !
Hence the loss of a star.

Oregon Lo Pro 3/8 Ripping Chain

Seems ok compared to Stihl. Maybe my imagination but it seems to have stretched more than the Stihl after similar use. Time will tell whether there is value in this compared to Stihl. As with ALL ChainsawBars purchases the delivery was prompt and efficient.


Excellent, and extremely prompt service, even in these trying times. Very easy site to use and had everything I needed. Thank you
