PRODUCT OVERVIEW
What Are Shearing Blades?
Shearing blades, also called guillotine shear knives or machine shear blades, are precision ground cutting tools used in guillotine and shear cutting machines for straight line cutting of metal sheets, plates, coils, and other materials. These blades are engineered to provide accurate cuts across a wide range of materials including mild steel, stainless steel, aluminium, silicon steel, rubber, paper, and plastic
Maxwell has manufactured shear blades since 1976. Every blade is CNC ground to ±0.01 mm tolerance and vacuum heat treated to 58 to 62 HRC. With advanced manufacturing techniques and in-house heat treatment, our shearing blades maintain sharpness and durability across millions of cuts, meeting the rigorous demands of industrial applications.
Whether you are running a steel service centre, a coil cut to length line, or a structural fabrication plant, Maxwell delivers shear blades built to outlast generic alternatives and reduce your cost per tonne cut.

What is the correct shear blade clearance?
Clearance equals 5 to 15 percent of material thickness. For 3 mm mild steel, set 0.15 to 0.45 mm. Too little causes blade wear and burrs. Too much causes torn edges. Maxwell engineers recommend the exact clearance for your machine and material on request

Why Choose Maxwell's Shearing Machine Blades?
Purchase managers calculate cost per tonne cut, not unit price. A blade that costs 20 percent more but lasts three times longer delivers far greater value for your annual spend. Here is the complete cost picture.
2 to 5×
Longer blade life
Mill-certified tool steel and in-house vacuum heat treatment reduce changeovers and minimise line stoppages during every shift.
4×
Life per blade set
Specify 4-edge geometry and rotate the edges as they wear. The same blade body delivers four working lives with a single purchase order.
40-60%
Saved on re-grinding

Frequently Asked Questions About Shear Blades
What are the uses of shearing blades in metal industries?
Shearing blades are used for straight line cutting of metal sheets, plates, and coils in steel service centres, cut to length lines, structural fabrication plants, automotive component manufacturing, appliance manufacturing, and scrap recycling. They also cut paper, rubber, and plastic in converting industries.
How long do Maxwell shearing blades last?
Blade life depends on the material being cut, sheet thickness, machine condition, and clearance setup. In typical mild steel applications, Maxwell D2 blades deliver 2 to 5 times the life of generic alternatives. With 4-edge geometry, that effective life multiplies again. Send us your application details and we will share realistic life estimates for your line.
What material should I choose for shear blades?
D2 is the standard choice for cold shearing of mild steel, stainless steel, and aluminium. D3 is used for high-wear cold shearing applications. H13 and H11 are hotwork tool steels suitable for hot shearing and applications requiring higher toughness. Our engineers will recommend the right grade once you share the material, thickness, and machine details.
Can I order custom-sized shear blades?
Yes. Maxwell manufactures shear blades from 100 mm up to 6000 mm in a single piece, with any width, thickness, hole pattern, or bevel angle. Send a drawing, an existing blade sample, or just your machine model number, and we will produce an exact replacement. No MOQ.
Can shear blades be sharpened or reconditioned?
Yes. Maxwell offers a re-grinding service that restores worn blades to original dimensional tolerance, typically saving 40 to 60 percent compared to buying new. Turnaround is 5 to 7 working days. We accept Maxwell blades and competitor blades.
Do shear blades require heat treatment?
Yes. Hardness directly determines edge life and resistance to wear. Maxwell vacuum hardens every shear blade in-house to 58 to 62 HRC, with uniform hardness across the full blade length, zero decarburisation, and zero distortion. We never outsource heat treatment.
How much do shear blades cost?
The cost of shear blades depends on several factors rather than a fixed price. The main price drivers include the blade length, tool steel grade (such as D2 or H13), number of cutting edges, and the quantity ordered. Custom dimensions, heat treatment, and special coatings may also influence the final price. Contact us with your machine specifications for an accurate quotation.
What is the difference between D2 and H13 shear blades?
D2 and H13 are both high-quality tool steels but are designed for different applications.
- D2 Shear Blades offer excellent wear resistance and edge retention, making them suitable for high-volume cutting of mild steel and other standard materials.
- H13 Shear Blades provide superior toughness and heat resistance, making them ideal for heavy-duty operations, thicker materials, and applications involving higher temperatures or impact loads.
The right choice depends on the material being cut and the operating conditions.
When should shear blades be reground?
Shear blades should be reground when you notice:
- Poor cut quality or rough edges
- Increased burr formation
- Higher cutting force or machine vibration
- Blade chipping or uneven wear
- Reduced cutting accuracy
Regular regrinding restores the cutting edge, improves cut quality, and extends the overall life of the blade.
What blade clearance should be used for stainless steel vs. mild steel?
Blade clearance varies depending on the material type and thickness. Stainless steel generally requires slightly larger clearances because of its higher strength and lower ductility, while mild steel can be cut with smaller clearances. Proper clearance helps reduce burrs, improve edge quality, and extend blade life. Refer to the clearance table below for general recommendations.
What is the difference between guillotine and swing beam shear blades?
Guillotine shear blades are used in machines with a straight vertical cutting action, providing high precision and excellent cut quality, especially for thicker materials.
Swing beam shear blades are used in machines where the upper blade follows an arc during cutting. These machines are generally simpler, cost-effective, and well suited for light to medium-duty sheet metal cutting.
