Thanks joey, I got the Metric set tonight ! (the last metric)
these will come in handy doing a valve adjustment on my 23hp briggs engine.
Good find there.
I picked up 2 individual phillips, I was suprised with how well they fit a phillips fastner.
I think there taper is like the JIS design. (a little more blunt tip)
If the center drilled hole is bigger than the drill bit the tips on the edges could be grabbing and pulling in, the magnetic drill wont stall. Just a guess.
