I used to have a hand blender of the stick type http://www.jmldirect.com/Power-Blitzer-With-Cook-Book-PP5125/

It was pretty good except the coupling teeth were made of plastic and looked prone to fast wear especially if someone hit the power button by mistake before engaging the coupling. After about 6 months the inevitable happened and I came home and the coupling had become a molten lump of plastic.

Does anyone know if there is a brand of blender of this type that has a metal coupling connection. It seems to be the most obvious thing that manufacturers are creating a built in expiry in these tools.

  • I've never heard the term "clutch gear", are you referring to a coupler/coupling? Or can you show a picture of what you're talking about?

  • Clutch was the word that came to mind but I think you are right, coupling is better.

Coupling design matters more than material. If you make your coupling short and thin, concentrating all the force in a small area, it will strip even it's metal. Conversely, a well-designed coupling is longer, so the strain is spread over a large area.

I have a Cuisinart CSB-76 hand (immersion) blender, and it has handled ice numerous times without any problems. It has a plastic coupling, but it is a good 3 cm long to spread out the force over more material. If I recall correctly, the professional-grade Vitamix blender also uses a plastic coupling, but with careful engineering to prevent problems.

It is now common to advertise kitchen appliances based on their motor's power (700 watts in this case), but many of these appliances will have mechanical failures if called on to deliver that much power. I suspect that you'd be better served to look for a lower-power blender from a reputable brand with good consumer reviews. I don't think the professional-grade immersion blenders I've used in restaurant kitchens are rated to more than 400 watts.

Personally, I recommend the Cuisinart CSB-76, and have never had a case where I needed more than its 200W.

    Also, if you go up to the professional-grade models (Robot Coupe, Dynamic, maybe Waring) they'll almost all have replaceable parts. Replacement couplings are usually $15-$20.

  • I like the way people on amazon have contributed images of the coupling for those cuisinarts, they must be impressed

  • I've had some nasty experiences with hand-blenders. A 800W model ended on the floor in pieces after my wife smashed it (on low it whipped the cream onto the wall). We're using Braun now. Jul 15, 2012 at 14:17

try hamilton beach. the models i looked at have metal coupling. but they are expensive

update:

i decided to purchase from walmart simply because if there's a problem with it, i can return/exchange it locally so i purchased a top of the line ninja. it works great. the only thing it doesn't do is liquify; if your mix has grapes of blueberries in it, there will be tiny chunks of grape/blueberry skins floating around. same with peppers. otherwise, the ninja is working out great for me. the blade bearings have never leaked, and it doesn't make a whole lot of noise i've been using it for three years now so yeah, what BobMcGee said goes

  • If you could link to one that you know of that would be very helpful, I found only rubber ones. Although that seems better than plastic and they look servicible.
