Annular Hole Cutter Hss 64 X 55mm Weld Shank 19.05mm

Features

• 64 mm diameter — for major clearance holes and structural penetrations.
• 55 mm cutting depth — shallow but large diameter, suitable for plate and structural sections.
• 19.05 mm (3/4') Weldon shank — two-flat drive ensures firm hold in magnetic drills.
• HSS material — high-speed steel construction suitable for heavy-duty metal drilling.
• Thin-wall, multi-flute design — enables faster penetration and efficient chip evacuation even in large sizes.

Benefits

• Large-hole efficiency: removes just the periphery ring, making large diameters faster than conventional twist drills.
• Smoother finish: fewer burrs and cleaner edges mean less finishing work.
• Reduced operator load: even with large size, feed pressure remains manageable, especially with shallow depth.
• Industrial durability: HSS body and Weldon interface deliver reliable performance under tough conditions.

Extra Information

• Use with a magnetic-base drill or drill-press fitted with a 19.05 mm (3/4″) Weldon shank arbor.
• A pilot pin (sold separately) is required for centring and slug ejection — ensure correct size for your arbor.
• When drilling stainless or harder materials, apply cutting fluid and maintain a steady feed to preserve cutter life and chip clearance.

Specifications

Safety

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