Hand Notching Shears Bessey left-hand 250 mm for cutting shaped openings (model BY D107-250L)

Bessey left-hand shaping shears BY D107-250L are manual notching scissors with a 250 mm blade length, designed for cutting shaped openings and notches in sheet materials. The tool features left-hand cutting geometry to accommodate left-handed operators or applications where a reversed cutting orientation improves visibility and control. These shears are intended for precise trimming and contour cutting in sheet metal, HVAC ductwork, roofing panels and general sheet fabrication tasks.

Advantages

The left-hand geometry provides improved line-of-sight and ergonomic handling for left-handed users or when cutting from the opposite side of a workpiece. A 250 mm blade length balances reach and control for contour cuts and notches. The robust construction of the cutting blades ensures consistent cutting performance for thin to medium gauge sheet materials. The manual operation allows precise incremental cuts without the need for power, making the tool suitable for jobsite or workshop use.

Suitable for

• Cutting shaped openings and notches in sheet metal
• HVAC duct shaping and trimming
• Roofing panel adjustments and edge trimming
• General sheet fabrication and repair work

Key specifications

• Blade length: 250 mm for extended reach and contour cutting
• Cutting orientation: left-hand geometry for reversed cutting direction
• Tool type: manual notching/shaping shears for precision trimming
• Suitable materials: thin to medium gauge sheet metals and similar sheet materials
• Operation: hand-operated shears without power source

How to use

Position the sheet material on a stable surface or secure it in a clamp to prevent movement. Mark the cutting line or notch on the sheet before starting. Hold the shears with the left-hand cutting orientation aligned to the intended cut so that the operator has a clear view of the cutting edge and the workpiece. Make steady, controlled strokes along the marked line, allowing the blades to follow the contour while avoiding excessive twisting or leverage that could damage the blades. For longer cuts, make progressive cuts and reposition the material as needed to maintain control. Inspect the cut edge and deburr if required.

Usage recommendations

Use appropriate personal protective equipment such as cut-resistant gloves and eye protection when cutting sheet materials. Select the left-hand shears when the cutting direction or operator preference requires reversed geometry. For materials at the upper limit of the tool's capability, consider progressive cutting and frequent blade inspection. Store the shears clean and dry and periodically check blade alignment and fasteners to maintain consistent cutting performance.
