Absolutely beautiful

I love these Kettlebells much I have them on display. A aesthetical throwback to the glory days of British Engineering. Feel great. Look great. Free delivery. 100% will order again.

Great service IFW.

Very efficient service from IFW. Good comms and fast delivery. The 12kg kettle bell is well made and has a comfortable handle. Very pleased and will be ordering some more.

Engineer Approved !

I'm just getting into Kettlebells, hence purchasing the 12kg as a 'starter' weight... However, as a lifelong engineer, I will say that these are very well finished kettlebells - the casting seams are fully ground flat, the casting itself is neat and not 'offset' like some cheap imports.
I'm happy with the item, definitely, but gutted that I found out I could have used a 10% Defence Discount Card link, literally the day after it was delivered...
Delivery was on a Saturday, having been ordered the day before, so no problems there.

Incredible Quality

Every aspect of the design and manufacturing process is geared towards giving you the highest quality product you can buy.  From the design and casting simulation packages to the automated moulding and robotic finishing processes, you can be sure that our cast iron kettlebells are the best available and certainly far superior to some product imported from overseas.


All our cast iron kettlebells are manufactured from recycled products, primarily car engine blocks and brake discs.  We operate to very tight environmental restrictions unlike foundries abroad, so you can be assured that we pay the highest respect and consideration to the environment.

Unique Design Features

Our products are designed with industry professionals and incorporate features and benefits that are not available from other suppliers.  Our kettlebells have pockets and recesses to allow the optional use of resistance bands for a more challenging workout.

Our cast iron weight plates are designed around the perfect size, shape and machined centre hole tolerances, ensuring the ideal fitment onto barbell bars and dumbbell bars.
