Need Help w/8.75 Gear Swap

Looking for any tips or insight...

Creating a pair of set-up bearings the for tapered 489 pinion shaft. What's the best way to do this? Using a honing tool and drill; taking forever... Geez! There's got to be a better way or maybe I'm just impatient.... Okay, I "KNOW" I'm impatient...

I used a die grinder with a medium burr on it and went gently with it until it slipped on and off with minor resistance.
