H13 Material: A top choice for high-quality blades. It’s very wear-resistant and tough, with great heat resistance. It won’t bend or chip during long, heavy cutting—ideal for high-strength rebar. Perfect for international trade (fewer replacements mean lower shipping and customs costs).
Cr12MoV Material: A hard, wear-resistant tool steel. It cuts high-hardness cold-rolled rebar and 16mm Grade 60 rebar without edge damage. Note: It’s less tough—avoid high-impact, large-gap cutting.
9CrSi Material: An affordable, practical option. It’s easy to harden and machine, good for cutting ordinary medium- and low-strength rebar. Great for small to medium projects.
Blades are cube-shaped with 4 usable cutting edges.
Rotate the blade to a new edge when one gets dull.
This design makes the blade last 4 times longer—fewer replacements, lower costs.
Blades use full grinding and vacuum heat treatment.
Each blade is hardened to HRC 50-61 (per our HardnessMap QC standards).
Prevents internal stress (a common issue with cheap blades that break easily).
Results in even hardness, sharp edges, and less chipping/dulling.
Made to strict OEM sizes—fits most RC-16 cutter heads perfectly.
Comes with strong mounting bolts for secure, gap-free installation.
Saves time on maintenance and replacement.
Square blades (our RC-16 standard): 4 usable edges, longer life—great for large-scale cutting.
Rectangular blades: 1 or 2 usable edges—best for small-tonnage cutters.
Different cutters (RC-16, RC-22, RC-25) have specific requirements for blade thickness, length, width, and bolt hole spacing.
Always follow your equipment’s instruction manual when choosing.
Ordinary Round Steel: Low hardness, easy to cut. 9CrSi or Cr12MoV works well (affordable and meets basic needs).
High-Strength Ribbed Rebar: Hard, ribbed surface wears blades quickly. Use H13 material—it’s wear-resistant and tough, reducing chipping risk for heavy cutting.
Our blades have optimized hardening and toughness to prevent brittle breakage when cutting high-strength rebar.
We offer custom solutions for your specific equipment and project needs—blades fit your work perfectly.
Compatible Models: RC-16, NRC-16, and similar 16mm portable cutters.
Materials: Cr12MoV, D2, or H13 (on request).
Cutting Capacity: Up to 16mm diameter rebar (SD345/Grade 60).
A broken blade stops rebar preparation on busy sites.
AlasMachinery’s RC-16 blades are reliable—they cut cleaner, faster, and last longer.
Keep your cutter working efficiently, not waiting for repairs.

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.
