Square blade: Four usable cutting sides. Rotate for new edges, longer service life. Best for large batch cutting.
Rectangular blade: Single or double side cutting. Fits small tonnage rebar cutting machines.
Models like GQ40, GQ50, GQ60 have fixed standards for blade thickness, length, width and bolt hole spacing.
Always follow the machine manual for exact blade size selection.
Precisely made as direct replacement parts for RC series portable rebar cutters: RC-16, RC-20, RC-22, RC-25.
Perfect tight fit with no shake or vibration during cutting. Protects blade bolts and cutter head from damage.
Ordinary round steel: Low hardness, easy to cut. Use 9CrSi or Cr12MoV to meet needs and save cost.
High-strength ribbed rebar: Hard surface with ribs that wear blades fast. Use H13 for strong wear resistance and anti-chip performance, suitable for continuous heavy cutting.
Scrap rebar: Heavily rusted with sand and dirt. Choose high-nickel material for better anti-wear performance.
Choose blades made with full grinding and vacuum heat treatment.
Even hardness across the blade, sharp edge lasts longer, not easy to chip or go dull.
Our custom blades use optimized hardening depth and balanced toughness, solving the common issue of blade breakage when cutting high-strength rebar.
Professional factory maker of industrial rebar cutting blades.
Factory direct supply, quality meets and passes OEM standard.
Strict metal material and heat treatment control for long-lasting blade performance.
Provide reliable, safe and cost-effective blade solutions for all rebar cutting jobs.

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.
