Annular Hole Cutter Hss 55 X 30mm Weld Shank 19.05mm

Extra Information

• Designed for use with magnetic-base drills or drill-presses equipped with 19.05 mm (3/4″) Weldon arbor.
• A pilot pin (sold separately) is required for centring and slug ejection — confirm size compatibility with your arbor.
• When drilling stainless steel or harder materials, apply suitable cutting fluid and maintain steady feed to protect cutter life and ensure clean chip removal.

Features

• 55 mm diameter — for large bolt holes, pipe penetrations and clearance applications.
• 30 mm cutting depth — shallow depth for large diameter holes in plate and structural elements.
• 19.05 mm (3/4') Weldon shank — two-flat drive for secure fit in magnetic drills.
• HSS material — high-speed steel construction suitable for steel and cast-iron applications.
• Thin-wall, multi-flute design — fast penetration and efficient slug ejection even in larger diameters.

Benefits

• Large holes made quickly: removes only the ring of material for faster large-diameter hole creation.
• Smoother finish: reduced burrs and cleaner edges for improved fit and less rework.
• Lower feed effort: despite large diameter, feed pressure remains manageable, especially with shallow depth.
• Durable tool life: HSS cutter body and Weldon interface provide industrial-level performance.

Safety

• Wear eye, ear and gloves protection; apply cutting fluid to control heat and assist chip evacuation.
• Ensure the magnet or base clamp is firmly secured and the workpiece stable before drilling; use a tether when working overhead or on angled surfaces.
• Do not use hammer/impact mode; maintain smooth, steady feed and allow the slug to eject naturally — stop immediately if feed slows or chatter begins.
• Disconnect power or disable magnet before changing cutters, pilot pins or shanks.
