Shear blade is a precise cutting tool for metal sheets, JSTMT manufacturers metal shear replacement blades with high quality material with custom sizes. it is for foot-operated squaring shears and guillotine with 2 or 4 side shear cutting blade design. Besides, we have Flat bar shear, angle shear, bar cutter, coper notcher blades, or custom metal shear blades for hydraulic ironworkers. The Rotary shear blades are a cost effective foot shear to crop the material for mild steel and stainless steel.


What are the Shear blades working Principles?

The shear knifes adopt the highest quality tool structural steel that ensures reliability and durability. It includes a top moving blade and a lower blade. the upper blade on the tool holder is fixed to the lower blade seats and adopts reasonable blade clearance for various thicknesses. These sheet metal shear replacement blades are positioned at an angle relative to each other. These two blades are forced past each other with the space between them determined by a required offset. A 5-degree shear angle decreases the force by about 20%. and the shearing blade gap adjustment can influence the quality of the cuts and tool life.

What is industrial shear blade sharpening and material?

To maintain a high level of productivity and ensure quality cuts, when hydraulic metal stomp shears blade sharpening is tough and can be surface ground to the same precision tolerances. The shear knife blades are made of special steel alloy, with full heat treated through the toughest conditions. The shear blade material can be SKD11, D2, or 6CrW2Si. Our blades are available in two-edge, and four cutting edges. We have manufactured blades for many shear brands: Accur, Amada, Trumpf, and LVD. We offer complete designs for unique, obsolete, as well as custom designs for homemade shears. we offer ironworker shear blades and replacement shear blades.

Metal Shear Blades Processing Equipment

JSTMT has been in Sheet Metal Fabrication Industry since 1985, with mechanical processing equipment: Multi-task Machine centers, Boring & Milling machines, and lathes facilities, our company delivers high-quality and reliable small break presses, hydraulic shears, and angle shear blades.



The shearing cutting blades are used for cutting steel plates into different strips with exacting tolerances. It is an important spare parts in the shearing machine. The shear knives include a top blade and bottom blade, and  can be used for cutting different material such as mild steel, stainless, and aluminum steel.

FAQ- Frequently asked questions

The replacement shear blade is a cutting blade for the metal shear machine.  It is composed of a top moving blade and a lower blade. the material is made of high chrome or high carbon steel for extended blade life. It works by clamping the material with the upper blade and the lower blades with a fixed cutting angle.

Shearing( die cutting) is a process that cuts stock without the formation of metal chips. If the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.

The Hydraulic metal cutting shear is a kind of machine that uses the moving upper blade and fixed lower blade to apply shear force to metal plates of various thicknesses by using reasonable blade clearance, to break and separate the plates according to the required size.

The replacement shear blades are available in two-edge for swing beam shear and four-edge for guillotine shear. and the material of the shearing machine blade parts is hardened to ensure consistent hardness; The hardening and tempering furnace can handle shear blades up to 16 feet in length.

  1. Two side edge shear knife. It is used for swing beam shear with two sides flat and two sides inclinable edge. the movement route is a circle line.
  2. Four side edge shear knife. it is used for a guillotine shear. the movement route is a straight line.
