In a past thread about these tools I remember someone saying they had a metal tool. The tools I make are made of Delrin plastic.
From McMaster-Carr:
Wear- and Water-Resistant
DelrinŽ Acetal Resin
Considered the workhorse of plastics, DelrinŽ acetal resin combines moisture resistance and a slippery, wear-resistant surface with an ability to hold tight tolerances. Often used for gears, bushings, impellers, and other parts that require its strength and rigidity.
I have used one of these tools in well over 250 assemblies of my DG-200 with no sign of wear in the bushings.

Say WHAT ? 4 different vendors I know all use plastic.
So the plastic deforms to the shape of the bushing and spreads out the load.
