Sawing and Shearing: What Metal Fabricators Need to Know Before They Cut

Metal cutting looks simple from the outside. You have material, you have a blade, and you need it smaller. But anyone who has sent an order back because cuts were off-tolerance, oversized, or distorted knows that the process behind the cut matters as much as the cut itself.

Sawing and shearing are two of the most common first-step processing services in the metals industry. Both are standard at every Boyd Metals location. Knowing which process fits your material, your geometry, and your tolerance requirements keeps projects on schedule and prevents scrap.

What Is Metal Sawing? 

Band sawing is the primary sawing method used at Boyd Metals. The process uses a continuous toothed blade stretched between two or more wheels, which delivers consistent, evenly distributed cuts through metal stock.

Band saws are the right tool when you need to cut bar, pipe, tube, or structural stock down to specified lengths or when you need miter cuts at specific angles. Boyd's CNC-programmable saws support faster cutting with closer tolerances, and sawing capacity reaches up to 24" square, suitable for single pieces or full mill bundles.

Horizontal vs. Vertical Band Saws

Horizontal band saws hold the material stationary while the blade travels down through the cut. This configuration is well suited for cutting long stock, pipe, bar, and structural sections to length.

Vertical band saws, also called contour saws, keep the blade path stationary while the operator or automation system moves the material across it. This allows for more complex cuts, including contours and profiles that straight cuts cannot achieve.

What Sawing Does Well

• Straight cuts on bar, pipe, tube, and structural stock
• Miter cuts at specified angles
• CNC programming for high-volume, repeatable cuts
• Narrow kerfs, which reduce material waste compared to wider-blade processes
• Consistent cuts across full mill bundles

When to Consider a Different Process

Sawing is designed for solid stock and tubular material. It is not the right choice for sheets or plates that require profile cutting, shape cutting, or cuts requiring tight dimensional tolerances on flat material. For those applications, plasma cutting, laser cutting, or shearing is a better fit.

What Is Metal Shearing?

Shearing uses an upper blade and a stationary lower blade forced past each other at an offset to remove a portion of flat sheet stock. Boyd's hydraulic shearing machines include both manually controlled and CNC-controlled shears, with nesting software to minimize material waste.

Shearing capacity at Boyd Metals is up to 1/4" thick and 144" long. The process is designed for flat sheets and is the most efficient way to make straight-line cuts at production volume.

Materials commonly sheared at Boyd include:

• Stainless steel (sheet)
• Aluminum (sheet)
• Brass (sheet)
• Bronze (sheet)

When material is loaded into the shearing machine, strong clamps hold it in position to prevent shifting under pressure. A back gauge or squaring arm ensures 90-degree cuts are square and consistent.

Guillotine vs. Swing Beam Shears

The Guillotine design shears drive the upper blade straight down through the material from start to finish. The rake angle is adjustable, which allows for more precise work on heavier or variable-thickness material with less distortion. This design typically has a higher shearing capacity and greater accuracy.

Swing-beam design shears move the upper blade in a circular arc through the material. This configuration allows faster strokes per minute and is well-suited for thinner materials at 1/4" and under. The rake angle on a swing beam shear is fixed.

What Shearing Does Well

• High-volume straight-line cuts on flat sheet stock
• Production efficiency with consistent, repeatable results
• 90-degree cuts held square with back gauge control
• CNC-controlled operation for closer, more consistent tolerances
• Nesting software support to reduce scrap

When to Consider a Different Process

Shearing is limited to straight cuts. It does not cut curves, profiles, or shapes. Material thickness for shearing at Boyd is limited to 1/4". For thicker plates or parts requiring shaped cuts, plasma cutting, oxy-fuel cutting, or laser cutting should be considered. For structural shapes and solid bar stock, sawing is the appropriate process.

Sawing vs. Shearing: Choosing the Right Process

Neither process is universally better. The right choice depends on your material form, thickness, and cut geometry.

If you are unsure which process applies to your job, Boyd's team can help you confirm the right approach before your order is placed.

When Another Process Is the Better Choice

Sawing and shearing cover a wide range of first-step processing needs, but they are not the only options. Boyd also offers:

• Plasma cutting - for carbon, aluminum, and stainless steel plate up to 1-1/2" thick, with CNC control and nesting software
• Oxy-fuel cutting - for heavier carbon steel plate up to 8" thick, CNC-controlled with DXF file compatibility
• Hi-Def plasma - for tighter tolerances on plate (±0.0625") and superior edge quality on carbon, aluminum, and stainless
• 2D and 3D laser cutting - for precision work on sheet and tube with the tightest tolerances available

If your project involves thick plate, shaped profiles, or tolerances tighter than shearing can hold, one of these processes may be a better fit. Boyd's processing team can review your specs and confirm the right routing.

First-Step Processing at Boyd Metals

Sawing and shearing are first-step processing services, meaning they prepare raw material for fabrication rather than finishing a final part. Getting this step right such as correct length, correct width, and correct squareness set up everything downstream.

Boyd Metals operates production-level saws and shears at each of its locations:

• Fort Smith,AR;
• Little Rock, AR;
• Joplin, MO;
• Oklahoma City, OK.

Every location maintains in-house sawing and shearing capacity, so you are not waiting on a subcontractor for your first cut.
