High-hardness rebar cutting blades are not necessarily prone to chipping. Whether or not chipping occurs depends primarily on the balance between hardness and toughness, not simply the hardness value itself. If only high hardness is pursued while neglecting toughness, the blade will become brittle,
Choosing the ideal rebar cutting blade requires balancing hardness and toughness. Key factors include the grade of steel being cut (e.g., Grade 60 vs. Grade 80), the blade's material composition (such as Cr12mov, H13 steel), and the specific heat treatment process. This article breaks down the technical specifications you need to look for—from edge geometry to wear resistance—ensuring you select a tool that maximizes service life and safety on the job site
