Material Comparison: H13 vs Cr12MoV vs 9CrSi
H13 (HRC 50-55)
Good toughness and hot hardness.
Best choice for HRB500 rebar, bars over 32mm diameter, rebars with weld marks, heavy impact and long continuous cutting work.
Cr12MoV / D2 (HRC 58-62)
Strong wear resistance with regular toughness.
Ideal for mass cutting HRB400 and lower grade rebar, small & medium bars below 25mm and automatic batch cutting lines.
9CrSi (HRC 55-60)
Average wear resistance at lower cost.
Fit for HPB300 plain round bar, light load and intermittent cutting, portable rebar cutters.
Pro Tip: Pick H13 for mixed rebar grades or welded spots to avoid blade chipping. Choose Cr12MoV for HRB400 bulk cutting to get longer service time between sharpening.

Frequently Asked Questions
Q: What size blade does GQ40 cutter need?
A: 83×83×26mm, same dimension for GQ42 and GQ45. Contact us for custom sizes on GQ50/GQ60.
Q: Which material lasts longer, H13 or Cr12MoV?
A: Depends on cutting material. Cr12MoV wears slower on clean small-size HRB400 in mass production. H13 holds up better for big-diameter, HRB500 or rebars with weld scars and heavy impact.
Q: Can these blades work on other brand cutters?
A: Yes, lots of Chinese, Turkish and European cutters adopt 83×83mm standard mounting. Send your machine model to check compatibility.
Q: Do you make custom blades for GQ50 and GQ60?
A: Yes, produce per customer samples or drawings, lead time 10-15 days.
Q: When to rotate the square cutting blade?
A: Rotate when cutting turns noisy, workpiece has obvious burrs or cutting resistance goes up. Normally every 2~4 weeks under regular working load.
Q: Can I get TiN / TiCN coated blades?
A: Optional PVD coating for extra wear life, send inquiry for coating price.
