Our take on the 90PX045 3/8 Low profile .043 gauge 45 Drive link Saw Chain

The Oregon 90PX045 is a 3/8-inch low-profile, .043-gauge saw chain with 45 drive links, built for 12-inch bars on small gas and battery saws. Its narrow kerf cuts a thinner slice of wood than Oregon's standard 91PX chain, so low-power saws hold higher RPMs and cut faster. It is a low-kickback chain that meets ANSI B175.1-2012 and CSA Z62.3. Arborists, landscapers and homeowners with compact saws are the intended buyers; it replaces R45, 90VG045G and 90SG045G.

Best forOwners of small battery or low-power gas sawsHomeowners trimming branches with a 12-inch barArborists and landscapers using compact top-handle sawsReplacing a worn 45-drive-link loop on a 12-inch bar
Pros
  • Narrow .043 kerf draws less power than standard 91PX chain
  • Lets small saws keep RPMs up for faster cutting
  • Low-kickback design meets ANSI and CSA standards
  • Made in the USA by Oregon
  • Sharpens at 30 degrees with an 11/64-inch file
  • Direct replacement for R45, 90VG045G and 90SG045G
Cons
  • Fits only 12-inch bars with 45 drive links, so no room for error on fit
  • Thin .043 gauge chain stretches and wears faster than heavier chain
  • Not for larger or high-power saws
  • Needs an 11/64-inch file, which many owners do not already own

What reviewers say

Owners of small battery and low-power gas saws report the narrow-kerf chain cuts faster and strains the saw less than the standard chain it replaces. Most complaints center on fit and on faster wear from the thin gauge.

What people mention
  • Cutting speedPraisedOwners say the narrow kerf cuts faster on small saws than standard chain.
  • Power drawPraisedUsers report the saw keeps its RPMs and bogs down less in the cut.
  • DurabilityCriticisedSome owners say the thin .043 gauge chain wears out faster than heavier chain.
  • Chain stretchMixedA few report it stretches and needs re-tensioning sooner than expected.
  • FitMixedBuyers stress matching the 45 drive links and 12-inch bar, since the wrong count will not fit.

About the 90PX045 3/8 Low profile .043 gauge 45 Drive link Saw Chain

This is an Oregon AdvanceCut 90PX045 saw chain loop, made in the USA. It has a 3/8" low profile pitch, .043 (1.1 mm) gauge and 45 drive links, and it fits bars with a 12-inch cutting length. It replaces R45, 90VG045G and 90SG045G.

The 90PX chain is designed for higher chain efficiency on small, low-powered gas and battery saws. The smaller .043 gauge cuts a narrower kerf and takes less power than the standard 91PX cutting system, which lets the saw maintain higher RPMs.

To check fit, look for a 90 stamped on the drive link, a count of 45 drive links, and 3/8LP 043 1.1mm stamped on the bar. The chain sharpens at 30 degrees with an 11/64" file. It is a low-kickback chain that meets the kickback performance requirements of ANSI B175.1-2012 and CSA Standard Z62.3.

Questions and answers

Will this chain fit my saw?
It fits saws running a 12-inch bar with 3/8-inch low-profile pitch and 45 drive links. Check your bar's drive-link count and pitch before ordering.
How is it different from Oregon 91PX chain?
The 90PX uses a .043 gauge and a narrower kerf than 91PX, so it takes less power from the saw. That suits small battery and low-power gas saws better.
What file do I need to sharpen it?
Sharpen at 30 degrees with an 11/64-inch round file. That is the file size Oregon specifies for the 90 series.
Is it a low-kickback chain?
Yes. Oregon lists it as meeting ANSI B175.1-2012 and CSA Z62.3 kickback performance requirements.
What does it replace?
It replaces Oregon R45, 90VG045G and 90SG045G, and the older 90PX045G part number.
Can I use it on a larger saw?
No. It is built for small, low-powered saws and 12-inch bars. A bigger saw needs a heavier gauge chain.
Where is the 90PX045 3/8 Low profile .043 gauge 45 Drive link Saw Chain cheapest?
At Northern Tool, for $11.99, 34% under what the other stores charge, as of our latest check.
