Introduction to Milling Cutter Blades for Milling Machines
Release time:2025-12-23
The milling cutter blade is the core cutting component of a milling machine, and there are two distinctly different types, each suited to entirely different machines. Below is key information about these two categories of blades: 
🔍 How to Choose and Key Considerations
Which accessory you choose depends entirely on the type of device you have:
If you’re operating a large pavement milling machine, what you need are milling teeth (cutting heads). When selecting them, the first thing to confirm is whether the shank diameter—typically Φ20 mm or Φ22 mm—matches your machine’s tool holder. Next, pay attention to the rotational design and the quality of the alloy, as these directly affect service life and efficiency.
If you’re operating a small walk-behind milling machine, you’ll need disc‑type cutters. Depending on the job, choose between round cutters—for deeper, rougher milling—and square cutters—for shallower, smoother surface preparation—and ensure that the cutter’s inner bore matches your machine’s arbor diameter (typically 4–6 mm larger than the arbor).
In addition, cutting‑tool technology continues to advance; for example, the industry‑leading brand Wirtgen has introduced tools featuring polycrystalline diamond (PCD) tips. Designed specifically for the rehabilitation of homogeneous asphalt pavement layers and ultra‑fine milling, these tools offer wear resistance several times greater than that of conventional cemented carbide, significantly reducing replacement frequency and enhancing paving smoothness.
💎 Summary and Recommendations
In short:
Select the type according to the equipment: bullet‑shaped cutter heads for large pavement milling machines, and disc‑type blades for small floor‑finishing machines.
Select the specification based on operating conditions: for large machines, consider the diameter; for small machines, consider the shape (round or square) and the number of teeth.
Consider technological upgrades: For high‑grade pavement milling, the long‑term benefits of PCD cutting tools can be evaluated.
If you can provide the specific make and model of your milling machine, I can help you further analyze the types of components to prioritize and the potential technical options available.
