UN curved right-hand shape-cutting shears for cutting openings model BY D107-275, 275 mm blade

UN curved right-hand shape-cutting shears model BY D107-275 feature a 275 mm cutting blade designed for creating openings and shaping sheet materials. The right-hand curved blade profile is intended to provide controlled cutting along curves and irregular outlines in thin metal sheets, plastics and similar materials. The tool is built for tradespeople and workshop environments where manual shaping and precise trimming are required.

Advantages

These UN shape-cutting shears combine a long 275 mm blade with a curved cutting geometry that helps maintain consistent contact with the workpiece when cutting arcs and non-linear shapes. The right-handed orientation supports natural cutting motion for right-handed users and improves visibility along the cutting path. The robust construction and blade length are suitable for repetitive workshop tasks and professional use.

Suitable for

• Cutting curved openings and contours in thin metal sheets (e.g., galvanized steel, aluminum)
• Shaping plastics and composite sheet materials
• Sheet metal trimming and edge finishing in workshops
• Manual pattern cutting and modification of pre-formed panels

When it may not be suitable

These shears are intended for hand-operated shaping of relatively thin sheet materials; they are not designed for cutting thick plate metal or heavy-gauge steel. For left-handed users the right-hand blade profile may feel awkward and reduce cutting accuracy. They are also not suitable for precision cutting of soft fabrics or for applications requiring powered or automated cutting.

Key specifications

• Blade length: 275 mm
• Blade profile: curved, right-hand orientation for shape cutting
• Primary use: manual cutting and shaping of sheet materials
• Suitable materials: thin metal sheets, plastics and similar sheet goods

How to use

Mark the intended cutting line or pattern on the workpiece before beginning. Use a steady, continuous cutting motion, keeping the curved blade aligned with the marked curve to maintain a smooth contour. For safer and more accurate results, secure the sheet material in a vice or with clamps to prevent movement. Do not force the shears through material thicker than recommended; instead, make multiple light passes or select a tool suitable for thicker gauges. Regularly inspect the blades for nicks and keep them clean to ensure consistent cutting performance.

What to consider before purchase

• Intended material thickness and type — suitable for thin sheet metals and plastics, not for heavy plate
• User hand orientation — right-hand curved blade is optimized for right-handed users
• Required blade length — 275 mm provides extended reach for larger curves and openings
• Workshop usage frequency — consider blade maintenance and potential sharpening needs

Usage recommendations

For best results, use the shears on materials within the tool's recommended thickness range, clamp the workpiece to reduce vibration, and follow progressive cutting motions along the curve. Store the shears in a dry place and periodically check blade edges to maintain cutting quality.
