  I'd use a Forstner .....

..... because it makes a much ceaner and precision bore , has far less blow out on the other side as well .

In any case you need to go through slowly . Not meaning rpm slow (cause upper range rpm helps make a cleaner cut) , but slowly as meaning "light" pressure on the drill's forward motion . Although not necessary , it's an advantage if you can get a backer block tight up to the inside to punch into a slight amount (someone may have to hold this for you while you drill the bore .

A Forstner "shaves" away material (between it's cutting ears) more like a plane does .

Anyway , it's plastic and the more pressure and slower rpm create more heat , and the larger the dianeter of the hole the more magnified that becomes ... higher speed and less pressure makes less heat . Heat softens and melts plastics , so the less the better when boring , cutting .

FE used a Forstner ...
