Drilling ferrite?
Posted: Sat Dec 10, 2011 4:24 pm
Hi,
I just bought some nominal 5mm ID ferrite to go around a 4.8mm cable. But the ferrite appears to be right at the end of its tolerance around 4.7mm. Cable doesn't fit.
I've drilled ceramic tiles with a 'conventional' HSS drill set I have (slowly working up in size, and dabbing water into the hole, fast drill speed, slow advance), so am going to attempt to open these up that last few fractions of a mm.
Any advice before attempting this?
