Brush Research DBC21218 Flex-Hone, 2-1/2 in / 180 Grit
Brush Research DBC21218, catalog model DBC2-1/2, is the 2-1/2-inch size of the listed 180-grit disc brake cylinder hone. Its flexible abrasive globules provide the described bore-finishing action. The nominal size is the key distinction from smaller DBC variants; the common tool shape does not make those variants interchangeable.

Product questions and answers
Is this interchangeable with DBC2-1/8?
It is a different nominal size: 2-1/2 inches rather than 2-1/8 inches. Choose using the bore and the manufacturer's tool-selection guidance.
Is it a rigid adjustable three-stone hone?
No. The described design uses flexible abrasive globules, rather than a rigid adjustable three-stone assembly.
Does the listing supply an RPM or lubricant specification?
No. Those operating parameters are not given in the available details. Use the tool manufacturer's instructions rather than guessing them.
