About Bucket Teeth
What is the difference between forged and cast teeth?
Forged teeth are made from heat treated alloy steel to help sustain wear resistance so you can often come to expect a longer wear life from forged teeth. The downsides are that there are more limits on shaping and forged teeth come at a higher cost.
Cast Teeth are made from austempored ductile iron and heat treated to offer maximum resistance to wear and impact. They are strong and lightweight in design and cast teeth are self-sharpening. They can last almost as long as forged teeth and they are significantly cheaper – making them more economical and cost effective.
When deciding which option is best, you need to understand the material being processed, abrasion level and impact the machine is subjecting the tooth to.
FYI – the largest difference is actually in impact – cast does not react well to high torsional forces breaking as it is a more brittle compound.
Whereas the forged tooth has long grains of steel giving it much greater torsional flexibility – so it will almost bend before it will break. Every solution is different so it’s important you understand whats required.
How can I extend the wear life of my bucket teeth?
Matching the correct tooth to your application can significantly reduce wear rates and increase ease of digging. This results in faster cycle time, less fuel consumption and reduced downtime.
Rotating your bucket teeth can help you determine wear patterns and increase productivity. Teeth located closer to the bucket corner often wear down faster. If your bucket is loaded on an angle regularly, then teeth will wear quicker on the leadingside.
Tungsten Coating is a protective covering on wear surfaces that dramatically reduces erosion, abrasion and corrosion. It can be used for a number of applications, including high abrasion and moderate impact uses. Having this coating on your bucket teeth and other wear parts can have a big impact on operational costs by lasting longer and increasing productivity of your machine.
I’m refurbishing a bucket. What Teeth System should I use?
This again, depends entirely on the machine you are using and the application that you are using it for. To give you a general idea though, we have broken down the two best options for you.
Mid-Large Sized Machines – V-Series Twist-on System
The twist-on system is the latest technology in bucket tip tooth and has some definite benefits.
The ease of installation and removal is second to none, requiring less time and man power
There is no hole in the adapter of the tooth which reduces any chance of snapping in this area
V-series teeth are fully interchangeable with Esco teeth. You don’t get locked into an expensive patented tooth.
These teeth are self-sharpening, maintaining and in fact increasing the digging ease as they wear which extends their life before they become too blunt
The one piece pin is fast and easy to install in the field
Mini Machines – Cat J Series System
It’s the cheaper option as you might only use one set per year
The CAT J Series System is the traditional choice and it’s used prolifically for a reason.
Weld-on adapters have excellent retention.
Industry-standard side-pinned design
Ability to retrofit means you can use a hammerless system
