The Oster 76 Size 0A is a detachable clipper blade for close haircutting, leaving a nominal 3/64 inch / 1.2 mm of hair. This length is useful for close fades, shaping the tops of flattops and clipper-over-comb work. It can also be used when blending out the line left by a size 1 blade, giving barbers another cutting length to work with as they refine a haircut.

The 0A replacement blade is identified by part number 76918-056. Distributor fit information lists the Oster Classic 76, Octane, Model One, Model 10 and Outlaw among compatible clippers. Match both the part number and detachable-blade system when selecting it for an existing machine.

The fixed cutting length belongs to the blade itself, so choosing size 0A selects that specific short-cutting option within your detachable blade set.
