Scrap gantry shear blade

Baler shear blades sit at the heart of scrap balers and combined shear-baler lines, cutting and cropping steel sections, rebar, and baled wire before compaction. The wrong blade chatters on the baling wire, rolls its edge in days, and jams the line; the right one runs weeks between regrinds. This 2026 spec guide covers what a baler shear blade is, which steel and geometry actually work, and how to size one to your machine. Bottom line: most baler and shear-baler lines run D2 (Cr12MoV) or H13 blades at 56–62 HRC with a 45–55° double bevel; the decisive factor is resisting baling-wire abrasion, so hardness above 60 HRC plus a robust bevel beats a keener edge; and GOOD-KNIFE grinds these to ±0.02 mm with matched pockets for leading baler brands.   Key Takeaways...
