DEWALT DWASHRIR Metal Shear/Cutter
The DWASHRIR metal shear offers 360-degree swivel head maneuverability, enabling cuts around complex profiles and tight corners typical of roof edging and flashing. It cuts up to 18 GA material, including sheet metal, corrugated panels, duct, asphalt shingles, and vinyl siding. The 1/4 in. hex shank ensures compatibility with standard drill chucks, making it a versatile option for retrofit work or on-site adjustments during roofing installations. Its impact-ready design helps maintain performance in demanding environments, with a compact form that reduces fatigue over extended tasks.
WEN Swivel Head Metal Shear
The WEN 3650 offers a swivel head and variable speed control, enabling precise starts and controlled cuts through 18-gauge sheet metal and up to 20-gauge stainless steel. A 4-amp motor provides robust cutting power while remaining lightweight, helping reduce operator fatigue on bigger roofing jobs. The trigger-activated mechanism allows fine-tuning of cutting speed—ideal when transitioning from straight sections to intricate trim work along eaves and ridges. This model balances affordability with performance for mid-range roofing projects.
Malco TSCM Corrugated Turbo Shear Attachment
The Malco TSCM turbo shear attachment fits drills to enable cross-cuts in corrugated metal roofing efficiently. Its lightweight construction and compact drill clamp design make it a practical choice for progressive roof panels and flashing work. While not a standalone electric shear, this attachment extends a drill’s capability for quick, straight cuts in corrugated materials, which can speed up sheet-metal installation and trim tasks on roof lines.
SHALL Electric Metal Cutting Shear
The SHALL electric shear features a 4.0-amp motor with a 360-degree swivel head and a variable speed range up to 2500 SPM. It’s designed for continuous cutting of 14GA sheet metal and 16GA stainless steel, offering a smooth, clean finish with minimal burrs. The double-cut design helps create curled edges at a controlled rate, reducing waste and messy chips. Its versatility makes it suitable for long straight runs as well as curved profiles on roof panels, vents, and flashing components.
DEWALT 20V Max Metal Shear/Cutter
The cordless DEWALT DCS494B offers 360° pivoting head access in tight spaces and a 7/32″ strip cut that curls as it exits the cutting area for precise, clean lines on metal roofing. An integrated LED work light helps illuminate surfaces in dim jobsites, improving visibility when trimming panels or trimming around obstacles. As a bare-tool model, it’s ideal for professional crews who already own compatible 20V batteries and chargers, enabling flexible on-site performance without cords.
Genesis GES40 Electric Shear
The Genesis GES40 is a 4-amp electric shear designed for rapid metal roofing cuts, with a 360° swiveling head for flexible operation. It handles common sheet metals used in roofing and flashing, enabling quick traverses along straight lines or controlled curves. The swivel head aids in aligning cuts around vents, ridges, and transitions, while the motor delivers steady performance across a range of materials. Its compact build supports workspace with limited clearance and overhead roofing work.
Buying Guide: Key Purchase Considerations
- Material compatibility: Roofing projects commonly use 14–18 GA steel, aluminum, or alloys. Choose a shear rated for your metal thickness to ensure clean cuts without stalling or fraying edges.
- Swivel head versatility: A 360-degree rotating head improves control when contouring along edges, curves, or corner details often found on roof lines and flashing components.
- Power source: Corded tools deliver consistent performance; cordless models offer mobility for on-site work but rely on battery life. Balance your typical worksite setup with tool choice.
- Speed control: Variable speed helps tailor cutting aggressiveness to different materials and shapes, reducing burrs and material waste.
- Ergonomics and weight: Roofing work can be strenuous. Lightweight designs with balanced weight distribution reduce fatigue during long sessions.
- Accessories and compatibility: Some attachments expand cutting options (drill attachments for corrugated metal, for example). Ensure compatibility with your drill, batteries, and chucks if considering attachments.
- Dust and debris management: Clean cuts produce fewer metal chips that can affect safety and precision. Look for designs that minimize heat buildup and burrs.
- Safety features: Guarding, locking mechanisms, and stable bases help prevent injuries, particularly when cutting overhead or in tight spaces.
When evaluating options, consider the balance between raw cutting speed and control, the ability to work in tight spaces, and how the tool integrates with existing equipment. For frequent on-site roofing work, modular setups that combine cordless power with a swivel head offer portability and practical versatility. For shops or crews with ample power, corded models with high-speed performance and robust durability can maintain consistency across long projects.
