Annular Cutter Extensions and Adapters
- Extension: Up to 18″
- Arbor Bore: 3/4″ or 1-1/4″ or MT2, MT3, MT4
- 3 flats for straight shank drill chucks and R8 shanks for drill presses available
Includes (testing):
- Extension for annular cutters
Benefits
- Converts standard length cutters into long reach solutions without needing to purchase specialty deep cut cutters.
- Extend cutter reach over the side or through an existing hole.
- Designed for fast attachment to annular cutters and arbors, minimizing downtime and keeping workflow efficient.
- Built from hardened, high strength materials to withstand heavy drilling loads and demanding job site conditions.
- Maintains cutter alignment for clean, accurate holemaking.
Applications & Usage
- Annular Cutter Extensions ideal for drilling through thick beams, columns, and plate where standard cutter depth is insufficient.
- Perfect for applications involving layered steel, welded assemblies, or stacked plate sections.
- Suitable for production environments where material thickness varies and long reach drilling is frequently required.
- Useful for onsite drilling during steel erection, equipment mounting, and infrastructure projects requiring deeper reach.
