The Blair 11364 1-1/4" Rotabroach Cutter is a professional-grade annular cutting tool engineered for efficient and precise hole creation in structural and automotive steel. Designed for technicians and fabricators, this cutter minimizes heat and tool load by extracting only the perimeter material. It delivers cleaner, burr-free holes in materials up to 1/2" thick, including mild steel, stainless steel, and aluminum, reducing secondary cleanup time.
Key Features
- 1-1/4" Cutting Diameter: Provides ample sizing for creating larger clearance, access, and mounting holes required in light trucks, passenger vehicles, trailers, and heavy equipment.
- Annular Cutting Technology: Expedites hole creation by extracting a solid slug, significantly improving drilling speed and reducing operator effort while effectively managing chips and heat build-up.
- Durable M2 High-Speed Steel Construction: Built to withstand repeated, rigorous use in demanding chassis, frame, and structural work, suitable for both shop and challenging field environments.
- Precision-Ground Teeth: Delivers clean, round holes with minimal burring, thereby reducing the need for secondary deburring and saving valuable rework time.
- Rotabroach System Compatible: Designed for seamless integration with standard Blair Rotabroach-style arbors and pilots, specifically requiring arbor 11007 for proper function.
Applications
The Blair 11364 is suitable for a range of professional applications, including chassis and frame modifications on light trucks and passenger vehicles, trailer fabrication, and heavy-equipment repair where larger diameter holes are essential. It excels at tasks such as installing suspension and accessory brackets, creating access holes in crossmembers, and establishing mounting points in various plate and structural shapes. Its robust design also supports consistent, repeatable hole quality in industrial production metal fabrication, plant maintenance, and construction steel work.
