It is possible for some of the turns to have shorted giving you less flux density. Also if the face of the magnet is pitted this can affect it's ability to 'stick'.
It also depends of the grade of ferromagnetic material you are trying to 'stick' to.

the magnet looks good no pitting ,,, if as said the coil turning were shorting is there a measurement i could take with say a multi meter??? im finding it difficult to get much info on magnetic drill faults
You would need a milli-ohm meter but would also need to know the DC resistance from the manufacturers.....
Have you tried on different grades of ferromagnetic metals ? The quoted figure was probably an 'up to' limit.

They are often DC and if one of the diodes has blown this could cause this problem.
a few interesting comments,, i will look for the diodes as this seems the easiest approach....i have a far amount of tools but not a milli ohm ,,,,i do have a PAT tester would this be of help????
for got to say but i did try this on a better quality steel and it was stronger but i can still pull it free,,, another point which i don't think maters is it 110 volt,,, considering its capable of 3 inch holes it seems weak magnet
How thick is the steel your sticking it too, it makes a big difference

They stopped making decent safes from ferrous metal a while back.
spot on alarm that is going to be one of its jobs,, with a 4mm cobalt driil
