How to drill a washer exactly
Those who were engaged in plumbing, various repairs of cars and motorcycles, probably fell into a similar situation when it was necessary to drill out the washer to the required diameter. It would seem, take and ream, what's the problem then? But not everything is as simple as it may seem at first glance.
If the washer is narrow or made of thin metal, then hold it, it is impossible to hold it somewhere.
If it is held in a vice, then most likely it will be confused. And if you hold, say, with pliers, the hole will not be smooth, as the puck will jump when drilling.
Ream the puck exactly with his own hands
I will use a bench drilling machine. Do everything you need on a wooden board. Without starting the rotation, we lower the drill bit close to the washer, thereby centering it exactly.
Carefully lift the drill without moving the washers. Put a wooden bar on top and press it with a clamp. Then we start the machine and drill the bar with a sandwich with a washer and bottom plate.
We remove the bar. Pull up the puck as it was pressed into the wood.
In such a simple way, you can smoothly and precisely waste the puck without any extra effort.
If necessary, you can irregularities and burrs grind file.

We take the drill, which we will bore the puck. We drill through hole in the bar in advance. Then put the puck on a wooden surface. Put a bar on top, adjusting the eye holes in the bar and in the puck. Clamp clamps.

Such tricks are very helpful in life, especially those who own them.
