Sutton annular cutters (core drills) and pilot pins cut large-diameter holes in steel plate and structural sections using magnetic drill stands or drill presses, removing only a ring of material rather than drilling a full-core slug — dramatically reducing power requirement and drilling time compared with conventional twist drills.

Where this product is used

Used with magnetic drill stands and drill presses for large-diameter hole-making in structural steel, plate, and fabricated sections in fabrication shops and on-site.

• Large-diameter hole-making in structural steel beams, columns, and plate for connection bolts, pipe penetrations, and cable trays in structural fabrication and construction.
• On-site magnetic drill use for drilling beam flanges, purlins, and structural connections where the workpiece cannot be moved to a stationary machine.
• Cutting precision-sized holes in tool plates, fixtures, and jigs in engineering workshops where hole accuracy and surface finish must be maintained.

Key specifications

Selecting the right option

Confirm the pilot pin diameter (commonly 7.98 mm) matches the annular cutter you are using — mismatched pilot pins can jam or produce off-centre holes. Use cutting fluid continuously throughout the cut; magnetic drills should be firmly attached to a flat magnetic surface. Annular cutters cannot be used in portable electric drills — they require a mag drill or drill press with the correct arbor.
