Buying Guide: The Road King Series of Cutters for Milling

June 8, 2023

Kennametal is a leading manufacturer of cutting tools, and our Road King line of products is particularly popular among construction and road maintenance professionals. These cutting tools are designed to improve performance, reduce downtime, and increase productivity on the job site.  

What is the Road King Series used for?

Road rehabilitation milling incorporates the removal of the top layer of existing pavement with a milling machine that uses a rotating drum with teeth. This process is also known as cold planning or profiling. When it comes to road rehabilitation recycling and pavement reclamation, the Road King series of cutting tools are perfect for cutting and breaking up asphalt, mixing, or stabilizing the base.  

The Road King Conical Bit Series

Road King cutting tools are made from high-quality materials, including tungsten carbide, which is known for its durability and resistance to wear and tear. This means that these tools can withstand the demands of heavy-duty applications and last longer than traditional cutting tools. 

Kennametal Road King Conical Bit Types Include:

  • Road King: Used for cutting asphalt and some concrete
  • Road King Diamond Flex Polycrystalline Diamond (PCD): Used for mainline milling, large highway projects, asphalt with incidental concrete and deep cuts
  • Stabilizer King: Used for full-depth cutting and stabilizing
  • Attachment King: Used with large machines and attachment drums for milling and drilling  


The Cutting Tooth

One of the key features of the Road King line is its advanced tip designs.  Using the right tip helps to minimize noise and vibration. This not only makes for a more comfortable work environment but also reduces operator fatigue and can improve overall efficiency. 

The type of cutting tools used in road rehabilitation milling will depend on several factors, including the type of material being removed, the condition of the road, and the desired final surface texture.  

It's important to note that the cutting tools used in road rehabilitation milling need to be periodically replaced as they wear down over time. The wear rate of the teeth will depend on several factors, including the type of material being removed, the speed and advance rate of the machine, and the design and condition of the milling drum. Regular maintenance and replacement of the cutting tools are critical to ensure that the milling machine operates efficiently and produces a high-quality milled surface.  

The Quick Change

Road King tools are designed for easy installation and removal, with a quick-change feature that lets users swap out worn tips in seconds. This saves valuable time on the job site and reduces the need for specialized equipment or training.  


Overall, Kennametal's Road King cutting tools offer a high-performance solution for road construction and maintenance professionals. With their durable materials, advanced design, and user-friendly features, these tools can help increase productivity and reduce costs over the long term.
