Shaped Hole-Cutting Shears left-handed ERDI 300 mm – No name BY D107-300L

Shaped hole-cutting shears for left-handed use, 300 mm overall length, model BY D107-300L from No name. These long-blade shears are built for cutting precise holes and shaped openings in sheet materials, offering extended reach and a left-handed cutting orientation to improve visibility and control for left-handed operators. The tool is intended for tasks such as HVAC ductwork, roofing, metal sheet fabrication and other sheet-metal working where accurate contour cutting and trimming are required.

Advantages

Left-handed geometry optimizes cutting line visibility and ergonomics for left-handed users, reducing the need to reposition workpieces. The 300 mm length provides greater reach and lever action for cutting through larger shapes or deeper sections while maintaining controllable blade movement. The shaped cutting edges are designed to follow contours and produce clean openings with reduced distortion of the surrounding material. The robust construction supports repeated sheet-metal use with consistent performance.

Suitable for

• Cutting holes and shaped openings in metal sheets for HVAC ducting
• Roof flashing and sheet-metal trim work
• General sheet fabrication and panel modifications
• Tasks requiring left-handed cutting orientation and extended reach

Key specifications

• Hand orientation: left-handed
• Overall length: 300 mm
• Blade type: shaped long-blade shears for hole and contour cutting
• Intended materials: thin to medium-gauge sheet metals and similar sheet materials
• Primary use: hole cutting, contour trimming and shaping in sheet work

How to use

Position the sheet material securely and mark the desired opening or contour. Use the shears with the left hand to align the shaped blades along the marked line, applying steady pressure and smooth cutting strokes to follow curves and produce a clean cut. For initial piercing, start at an edge or create a small starter hole using an appropriate tool, then feed the shears into the cut and continue along the marked path. Periodically check blade alignment and material support to avoid burrs or deformation.

Usage recommendations

Use appropriate personal protective equipment such as cut-resistant gloves and eye protection, clamp or support workpieces to prevent movement during cutting, and avoid forcing the tool through material that exceeds the intended gauge. Regularly inspect and maintain blade sharpness to ensure accurate, safe cutting performance.
