that's a bit excessive.
I do use a quality housing cutter - I've had good luck with both Pedros and Park Tool - but then I just use a small punch or 2mm allen key and stick it in the housing and work it around in a slow, gentle circle. This spreads the end of the housing into a nice open circle.
That's all you need to.
