Halls Rotabroach™ HSS Raptor Cutter 40 x 25mm | RAP400

Halls RAP400 Rotabroach™ HSS Raptor Annular Cutter – 40mm x 25mm

Halls RAP400 Rotabroach™ HSS Raptor annular cutter is designed for fast, accurate holemaking with magnetic drill stands, producing clean holes while removing less material than conventional twist drilling. It’s a practical choice for fabricators and site engineers who need consistent performance in steelwork and general metalworking.

With a 40mm cutting diameter and 25mm cutting depth, the RAP400 is suited to common structural tasks such as handrail plates, base plates and bracket work, where a tidy finish and efficient cutting action help keep productivity high.

Key Features

• 40mm annular cutting diameter: Ideal for creating larger clearance holes and connection points in steel fabrication and installation work.
• 25mm cutting depth: Suitable for drilling through common plate thicknesses without over-specifying the cutter length.
• HSS Raptor cutter design: Built for efficient holemaking with specialist tooth geometry intended for annular cutting applications.
• Reduced material removal: Annular cutting produces a slug rather than full chip removal, helping reduce load compared with drilling the full diameter.
• For magnetic drilling setups: Designed for use with magnetic drill stands and appropriate arbors for annular cutters.
