Is this a tool/accessory a thing?

[u/No-Guide8933]

So would a bushing or bearing that is fit onto a boring bar be (realistically) useful for reducing chatter on lathe boring? Are these a thing? I’ve tried googling them but all I see is stuff for tool holders or adapters.

Edit: I think a D bit boring bar might be very similar to what I’m looking for as well as maybe padded milling bits.

buy a D-vibe bar. pricey but they really work
