A tooth system Komatsu says is more productive, reliable and safer than its predecessor will now be made available as standard across Komatsu’s excavator and wheel loader range.

Developed by Komatsu subsidiary Hensley Industries, the new Kprime Tooth System has been designed as a stronger and longer lasting product, offering additional safety and productivity enhancements, the company says.

Replacing Hensley’s XS Tooth Systems range of teeth and other ground engaging tools (GET), Kprime Tooth System is suitable for excavators with operating weights from 4 tonnes to 400 tonnes, and for loaders weighing from 10 tonnes to 200 tonnes.

Safety enhancements to the Kprime Tooth System include an intuitive locking system, pry slots on the tooth and wear cap for easier removal of worn parts, a low-torque pin for easier tooth changes, and the weight of individual units marked on each part.

The teeth have also been redesigned to make them more reliable and productive – with an increased wear material so they penetrate better and don’t need to be changed as often.

The adapter nose design has been improved, making it 10 per cent stronger, with a new fit making the teeth more stable and reducing the potential for accidental unlocking.


The teeth have been designed to be both more reliable and durable


Komatsu’s national business manager for GET, Phillip Walker, says the Kprime Tooth System builds on the XS, offering "significant advances in safety, ease of use and extended periods between tooth changes".

"Kprime teeth are rotatable, to further extend life, while wear indicators on the wear cap and fastener let users know when those parts need to be changed," he says.

"And losing teeth into a crusher or conveyor is far less likely to occur with Kprime Tooth System due to a new locking system that means no torque loss after multiple cycles, ensuring the holding pin remains locked throughout the life of the tooth."

A range of tooth types is available for all machine sizes across both the excavator and wheel loader range, from light-duty applications, through to the toughest and most challenging rock and abrasive material conditions.

Buckets fitted with Kprime adaptors have the option of using different styles of teeth to meet individual digging and loading requirements.

"While Kprime teeth will be offered as standard on all Komatsu excavators and loaders, this system is also ideal for all other brands of earthmoving and mining equipment, from compact utility-class machines up to large mining machines," Walker says.

Kprime, along with all Komatsu parts, can also be ordered via Komatsu’s ecommerce platform,
