Pick the right blade
Make blades last longer
Ensure stable cutting
Meet modern industry needs for speed and efficiency
Industry rules (including guidelines from the Ministry of Housing and Urban-Rural Development) demand better cutting precision and more durable blades.
Old, surface-hardened blades cause frequent chipping, machine stops, and fail to meet rebar end-face flatness requirements.
We use high-quality H13 (SKD-61) and D2 tool steels (D2 is a high-hardness, high-wear material for ordinary round steel).
We add full-body vacuum heat treatment—a key technology for 2026 blade performance.
H13 (American AISI standard): More vanadium, better wear resistance and toughness.
SKD-61 (Japanese JIS standard): More molybdenum, better high-temperature strength.
2026 formula ensures core-to-surface hardness of HRC 58-62 (matches high-quality tool steel standards).
Uniform hardness prevents blades from breaking—even when cutting multiple rebars at once.
Solves the common problem of brittle fracture when cutting high-strength rebar.
Blades keep their sharp edge during continuous, high-speed cutting (which creates high heat).
Vacuum heat treatment avoids oxidation and decarburization, and removes gas from the steel.
H13 steel stays hard (≥45 HRC) at 600℃, ensuring stable performance during long, intense work.
Each blade is precision-ground on all four edges.
Extends service life by 4x, reducing inventory costs.
Better for large-scale processing (fits 2026 needs for speed and low cost).
Fits perfectly in the blade seat, eliminating "chatter" (which wears down the machine’s cutting head).
Meets JGJ107-2016 standards for rebar mechanical connection.
Ensures flat rebar end-faces (no bending, distortion, or horseshoe shape).
Mainstream high-quality material in 2026.
Great wear resistance, toughness, and thermal fatigue resistance.
No deformation or chipping during long, intense cutting.
Ideal for high-strength rebar (Grade 60, 75) and high-hardness cold-rolled rebar.
Lasts 40% longer than regular blades (after vacuum heat treatment).
Best for scrap rebar (corroded, with sand/dirt that wears blades).
Excellent corrosion and wear resistance.
Extends blade life in harsh conditions.
Square blades: 4 usable edges (rotate to extend life). Good for large-scale processing and high-speed lines.
Rectangular blades: 1 or 2 edges. Designed for small-tonnage machines (e.g., below GQ40). Good for small projects with low cutting frequency.
Different machine tonnages (GQ40, GQ50, GQ60) have strict standards for blade thickness, length, width, and bolt hole spacing.
Parameters match mainstream machines (e.g., Topmac GQ40, GQ50).
Follow the machine manual to ensure a perfect fit (avoids safety risks and cutting defects).
Ordinary round steel: Low hardness and cutting resistance. Use D2 (controls costs, fits non-mechanical connection projects).
High-strength ribbed rebar (Grade 60, 75): High hardness, ribbed surface wears blades. Use H13 (SKD-61) (reduces chipping, supports continuous cutting, meets 2026 precision standards).
Scrap rebar: Corroded, with sand/dirt. Use high-nickel materials (ensures durability in harsh conditions).
Uniform hardness: Vacuum heat treatment removes internal stress (no local brittleness or deformation).
Stable sharpness: Precision grinding ensures sharp edges and micron-level flatness (reduces cutting resistance, improves efficiency).
Low failure rate: Less chipping or dulling (avoids costly machine stops, fits 2026 low-downtime needs).
Optimized hardening depth and toughness (solves brittle fracture when cutting high-strength rebar).
Make non-standard blades from your drawings, dimensions (length x width x thickness + hole size/ spacing), and performance needs.
Fits all machine brands and models.
Strict material and hardness testing (ensures quality and stability).
High-performance, maintenance-free spares (ready to install).
Our 2026 blades last 40% longer than standard options (keeps projects on time and on budget).
Global supply, reliable after-sales service and technical support.
Helps you meet 2026 standards and gain market advantages.
