Here is a recent publication that discusses the differences between M1 and
M2.

Subject: [ZOOARCH] Cattle teeth: M1 M2; the accessory pillar
Dear all
The following is now available on BoneCommons.
Cattle teeth: differences between first and second molars, and variability
in the accessory pillar
In the report on the cattle remains from Ferry Fryston, Yorkshire, two
aspects of particular relevance to methods for studying age at death from
cattle teeth were published. Differences in the morphology and size of first
and second molars are described, which may allow loose teeth to be
identified in most cases and therefore be more easily used in age estimates.
And the height of the accessory pillar (the small pillar which sits between
the first and second elements in molar teeth) was measured for all three
molars and its variability shown. The variability was greatest in M3, which
is used in some summary methods for defining older cattle. The work was
published as Appendix 11, on a CD, and the pdf is presented, with some
additional tables, omissions, errata and photographs.
