Will this blade fit my Hamilton Beach Commercial blender?

It fits models that use part number 990379900. Match that number against your blender's manual or the old blade before ordering, since Hamilton Beach Commercial uses several different assemblies.

What is included with the blade assembly?

You get the three-wing metal blade on its shaft with the hex nut, plus the black cylindrical coupling with the splined socket. The jar and base are not included.

Is it dishwasher safe?

The listing says yes. Many owners still hand-wash blades to keep the edges sharp and avoid trapping food in the coupling.

Is $16.08 a good price?

It is the only new price we track as of November 5, 2026, at Schedule73Parts. For an OEM blade assembly that is a modest cost, and it is far cheaper than replacing the blender.

Remove the jar from the base, unscrew the old coupling, and swap in the new assembly, seating the splined socket fully. Tighten the hex nut firmly and test with liquid before blending ice.
