Hamilton Beach Blade Assembly - 990048201 vs Hamilton Beach Commercial 990379900 Blade Assembly

Both are genuine Hamilton Beach blade assemblies, but they are not interchangeable. The 990048201 is the consumer blender blade for select home Hamilton Beach blenders, with a plastic body and metal blade and screw. The 990379900 is a commercial part with a three-wing blade and a splined coupling, built for heavier use. Buy the one that matches your model number; fit is the whole decision here.

• Choose the 990048201 if you own a home Hamilton Beach blender and need the OEM blade that matches its jar base.
• Choose the 990379900 if you have a Hamilton Beach Commercial blender and need the three-wing blade assembly with the splined coupling.
