now i bought these

50 off for £16 ish about 34p per disc i hadnt used them till today and i was very surprised used one where normally id have used 3-4 cutting 3mm plate
shame my grinders letting go had it in bits earlier trying to chase a "new noise " but no joy. it still works but holding it at arms length with your eyes closed hiding behind some 3mm ali the cuts arent so accurate
