1-1/4" Rotabroach Cutter - Blair Equipment

The Blair 11364 1-1/4" Rotabroach Cutter is engineered for professional technicians and fabricators requiring efficient and precise hole creation in structural and automotive steel. This annular cutting tool minimizes heat and tool load by extracting only the perimeter material, delivering cleaner, burr-free holes and reducing secondary cleanup time compared to conventional drilling methods. It is designed to cut holes up to 1/2" thick material, including mild steel, stainless steel, and aluminum.

Key Features

• 1-1/4" Cutting Diameter: Provides ample sizing for larger clearance, access, and mounting holes on light trucks, passenger vehicles, trailers, and heavy equipment.
• Annular Cutting Technology: Extracts a solid slug, significantly improving drilling speed and reducing operator effort while effectively controlling chips and heat build-up.
• Durable M2 High-Speed Steel Construction: Built to withstand repeated use in demanding chassis, frame, and structural work on mild and structural steel, suitable for both shop and field environments.
• Precision-Ground Teeth: Delivers clean, round holes with minimal burring, thereby reducing secondary deburring and rework time.
• Rotabroach System Compatible: Designed for seamless integration with standard Blair Rotabroach-style arbors and pilots, requiring arbor 11007 for use.

Applications

This cutter is commonly utilized for chassis and frame modifications on light trucks and passenger vehicles, trailer fabrication, and heavy-equipment repair where larger diameter holes are necessary. It is well-suited for installing suspension and accessory brackets, adding access holes in crossmembers, and creating mounting points in plate and structural shapes. In industrial settings, it supports production metal fabrication, plant maintenance, and construction steel work, ensuring consistent, repeatable hole quality.
