I think this newsgroup is probably the best place to try and work out

It was found on landfill in the UK, there were lots of them, and they
look familiar, but I can't place where.

Carbide cutting tip for an asphalt-concrete pavement grinder or
'profiler'. They use them to grind the old road flat and undercut the
edges at the curbs before laying a fresh layer of asphalt on top.

Or a 'rock wheel' trencher, looks like a huge circular saw to buzz a
trench in sandstone or shale for water mains and other utility lines.
WARNING: You have to know where all the other underground utilities
are when using this machine, because if you find them with the wheel
the results will not be pretty...

(Not me, but a true DAMHIKT. Pacific Bell told the trencher
operator not to worry - their trunk lines were in old clay ducts 8'
down, and the cross-cut trench was set at 5' to leave plenty of room.
They were really at 4' down, and the trencher neatly sawed through a
half dozen 3600-pair cables... Let the finger-pointing commence.)

Something like that happened to an old neighbor...

Maynard's farm had two driveways about 200 ft. apart. He needed to replace
the culverts under them. Knowing the phone trunk line was buried in that
ditch, he called the phone company to locate and mark the cables. Then,
they took a backhoe to the first driveway. And dug through the cable. And
shut off long distance service to two counties. Two days later, they had
the cable spliced. Maynard, of course, insisted they double check their
marking of the other driveway. They insisted it was correct. And, yup, the
backhoe cut through the cable again about eight feet from where the phone
company said it was...
