Quality Materials: We use Cr12MoV or H13 tool steel for strong hardness and toughness.
Advanced Heat Treatment: Every blade gets vacuum induction hardening (50–62 HRC) to avoid early dulling.
Perfect Fit: Precision-ground to fit most global brands (GQ, GWH, hydraulic portable cutters).
4-Sided Use: Most block-style blades are reversible—4 sharp edges for the price of 1.
H13 Material: Popular high-quality choice. Wear-resistant, tough and heat-resistant. Great for long, heavy cutting of high-strength rebar (no bending or chipping).
Cr12MoV Material: Hard and wear-resistant (harder than regular alloy blades). Good for hard cold-rolled rebar. Note: Less tough—don’t use for high-impact or large-gap cutting.
9CrSi Material: Cheap and practical. Easy to process. Good for ordinary medium- and low-strength rebar (ideal for small/medium projects).
Square: 4 usable edges (rotates to last longer) – best for large-scale work.
Rectangular: 1 or 2 usable edges – best for small-tonnage cutters.
Size Matching: Machines like GQ40, GQ50, GQ60 need specific blade size (thickness, length, bolt holes). Follow your machine’s manual.
Ordinary Round Steel: Soft and easy to cut. 9CrSi or Cr12MoV works well (saves money).
High-Strength Ribbed Rebar: Hard, ribbed surfaces wear blades quickly. Use H13 (resists wear and chipping for heavy use).
Our custom blades have better hardening and toughness—fixing the common problem of breakage when cutting high-strength rebar.
H13 blades are great for international trade: they last long, so you replace them less (saves shipping and customs costs).

"Seeing is believing. This field test showcases the ALAS Rebar Cutter Blades in action at a high-intensity construction site. We documented the real-world performance and durability of our blades to provide you with the transparency you need before making a purchase.
Proven Durability: Our blades are forged from premium D2 and H13 tool steel, vacuum-hardened to ensure they can handle high-tensile rebar without chipping.
Precision Engineering: Watch how cleanly the blades shear through of rebar, minimizing end-deformation and reducing strain on your machine's hydraulic system.
Lower Cost-Per-Cut: Real-world data from this test shows a significant reduction in tooling replacement frequency, saving you both time and money on the job site.
Technical Specifications:
Material: H13
Hardness: 50-55 HRC
Compatibility: Universal fit for all major mechanical and hydraulic rebar cutters.
Watch the full test to see why ALAS is the trusted choice for heavy-duty infrastructure projects."
Based on different working conditions and budget requirements, we offer three general industrial-grade alloy steel materials:
9CrSi (Alloy Tool Steel): An economical choice. It has good hardenability and machinability, suitable for cutting ordinary medium-to-low strength rebar, and is widely used in small and medium-sized projects.
Cr12MoV (Cold Work Die Steel): High-end wear-resistant type. High carbon and high chromium content, after heat treatment, it has excellent wear resistance, making it an ideal choice for continuous cutting of high-strength rebar. Its service life is much longer than 9CrSi.
H13 (Hot Work Die Steel/Red Hard Steel): High toughness and high wear resistance. It exhibits excellent resistance to chipping and thermal stability in rebar cutting applications, especially suitable for high-speed production lines or online cutting of hot-rolled rebar, and cutting of ultra-thick rebar and composite materials of scrap rebar.
Chipping is usually caused by the following factors:
Insufficient toughness: Using ultra-hard but low-toughness materials to cut large-diameter or ultra-hard rebar can easily lead to brittle fracture. In this case, we recommend switching to H13 material, as its excellent toughness can effectively absorb impact forces.
Improper clearance: Too large or too small a gap between the upper and lower blades will lead to uneven stress, resulting in chipping.
Insufficient heat treatment: Internal stress is not completely eliminated. All our blades use vacuum heat treatment technology to ensure uniform hardness from the inside out, greatly reducing the chipping rate.
Wear resistance: Cr12MoV has significantly better wear resistance than 9CrSi. Under the same working conditions, the number of cuts for Cr12MoV is usually 2-3 times that of 9CrSi.
Cost: 9CrSi is more cost-effective, suitable for projects sensitive to initial purchase costs; although the unit price of Cr12MoV is slightly higher, its lower replacement frequency results in a lower overall cutting cost per ton of rebar.
For high-strength or ribbed rebar, we strongly recommend H13:
If you are facing extremely high operating intensity and are concerned about downtime due to blade chipping, choose H13. Its impact fatigue resistance is top-notch in the rebar processing industry.
Yes. We understand that blade specifications vary among different equipment brands (e.g., from Italy, Germany, or China). We are equipped with a full set of CNC machining equipment, and you only need to provide the following information:
Detailed drawings (including length, width, thickness, and hole dimensions).
Material requirements (9CrSi, Cr12MoV, or H13).
Specifications of the workpiece to be processed (rebar diameter and strength grade).
We can provide a 1:1 precise customized solution.
Regular rotation: Our blades are usually designed with 4 or 8 cutting edges. Please rotate the blade promptly when one cutting edge becomes dull.
Tighten bolts: Ensure the blades are securely installed. Any slight looseness will cause destructive impact during the cutting process.
Control the gap: Adjust a reasonable blade gap according to the rebar diameter, usually about 10% of the rebar diameter.
