Product Introduction

Milling and planing teeth, also known as milling and planing machine cutters or road planing teeth, are basically categorized by specifications into Φ20mm, Φ22mm, Φ38mm, and others.. Regarding the materials: The cutting teeth section is generally made of tungsten alloy, with a hardness between 88-89 HRA. The blade body is typically selected from 42CrMo wear-resistant material, refined through cold and hot forging processes. The heat treatment hardness ranges from 42-44 HRC. The hardness should not be too high, as excessively high hardness may actually lead to fracture of the handle. The washer is made of a hard and elastic 65Mo material, with a diameter of 44mm. It prevents direct wear on the tool holder during the milling and planing operations of the cutter head, effectively protecting the service life of the tool holder. A milling and planing tooth consists : alloy, tooth body, retaining spring, and retaining ring.
