I will provide you with usage suggestions based on material selection, equipment matching, cutting material, and manufacturing process:
The blade material directly determines its hardness, toughness, and service life. Choose the material according to your cutting needs:
Currently the mainstream high-quality blade material on the market, possessing both extremely high wear resistance and toughness, with outstanding resistance to thermal cycling. Even during long-term, high-intensity continuous cutting, it is not prone to deformation or chipping, making it suitable for large-scale processing of high-strength rebar.
High-hardness, high-wear-resistance tool steel. Its hardness far exceeds that of ordinary alloy blades, and it can handle the cutting needs of high-hardness cold-rolled rebar. Note that its toughness is relatively weaker; it is recommended to avoid using it in high-impact, large-gap cutting conditions.
An economical and practical choice. It has good hardenability and machinability, suitable for cutting ordinary medium- and low-strength rebar, and is widely used in small and medium-sized projects.
Shape Matching: Common blade shapes are square (four sides usable) and rectangular. Square blades allow for the rotation of four cutting edges, significantly extending their service life, suitable for large-scale processing scenarios; rectangular blades are mostly single-sided or double-sided, suitable for small-tonnage cutting machines.
Size Matching: Different tonnage cutting machines (such as GQ40, GQ50, GQ60) have specific standards for blade thickness, length, width, and bolt hole spacing. Selection must strictly follow the equipment's instruction manual.
Ordinary Round Steel: Low hardness and low cutting resistance. 9CrSi or Cr12MoV materials are sufficient, meeting basic cutting needs while controlling costs.
High-Strength Ribbed Rebar : High hardness, and the ribbed surface structure easily wears down the blade. It is recommended to use H13 material. Its excellent wear resistance and toughness can effectively reduce the risk of chipping, making it suitable for high-strength continuous cutting. Scrap rebar: Severely corroded surface, containing sand and dirt, causing significant wear on the blades. High-nickel materials are preferred;
Blades processed through full grinding and vacuum heat treatment are preferred. These blades have a uniform hardness distribution, good edge retention, and are less prone to chipping or dulling during cutting.
Our blades, through optimized hardening depth and toughness, address the common industry problem of brittle fracture when cutting high-strength rebar
Base Grade | Steel Category | Chinese Standard GB/T 1299 | American Standard ASTM | German Standard DIN (W-Nr.) | Japanese Standard JIS |
H13 | Hot Work Die Steel | 4Cr5MoSiV1 | H13 | 1.2344 | SKD61 |

9CrSi | Alloy Tool Steel (Cutting Tool Steel) | 9CrSi | 1.2108 |
Core Principles: Power off and stop completely → Confirm no pressure → Standard disassembly and assembly → Precise adjustment → Test run verification. Avoid pressurized and live electrical operation throughout the process to prevent blade pinching injuries and accidental equipment startup risks.
Turn off the main power supply of the cutting machine, unplug the power cord/switch off the circuit breaker; manually rotate the equipment flywheel to confirm that the blade holder has no inertial movement and is completely stationary, preventing accidental equipment startup.
Loosen the unloading valve of the equipment's hydraulic system (for hydraulic models), completely release the hydraulic pressure inside the blade holder to prevent the blade holder from suddenly rebounding; remove the safety guard and fixing clips at the blade, and clean up rebar scraps and debris between the blade holder and the blade to ensure unobstructed disassembly and assembly space.
Use a special wrench to loosen the blade fixing bolts (disassemble in a diagonal sequence to prevent deformation of the blade holder), strictly avoid directly striking the blade/bolts with a hammer; during disassembly, steadily support the blade with your hand and place the old blade properly in a non-slip, non-impact area.
Smoothly fit the new blade to the positioning surface of the blade holder, confirm that the blade installation direction (cutting edge facing the shearing side) is correct, and gradually tighten the fixing bolts in a diagonal sequence (even torque to prevent blade misalignment); adjust the gap between the moving and stationary blades, the conventional rebar cutting gap is controlled at 0.1~0.3mm, a gap that is too large is prone to material jamming, and a gap that is too small is prone to blade wear.
Reset and lock the safety guard; after switching on the power, jog the equipment 2-3 times without load, check that the blade holder runs smoothly and the blade is free from jamming/abnormal noise, and after confirming that the shearing action is normal, then perform a rebar test cut. If the test cut is successful, it can be used normally.
