Annular Hole Cutter Tct 20 X 55mm Weld Shank 19.05mm

Extra Information

• Designed for magnetic-base drills or compatible drill-press setups using a 19.05 mm (3/4″) Weldon shank arbor.
• A pilot pin (sold separately) is required for centring the cutter and ejecting the slug — ensure you use the correct size for best results.
• For stainless or harder materials, apply cutting fluid and maintain steady feed to preserve carbide life and prevent chip clogging.

Features

• 20 mm diameter — creates accurate holes for anchor bolts, flanges and conduit pass-throughs.
• 55 mm cutting depth — accommodates common plate thicknesses and stacked material.
• 19.05 mm (3/4') Weldon shank — two-flat drive ensures secure clamp in most mag-drills.
• TCT (tungsten-carbide-tipped) teeth — built for long life when cutting structural steel and cast iron.
• Thin-wall body with multi-flute design — fast penetration, efficient chip removal and less load on machine.

Benefits

• Increased productivity: only the ring of material is removed (not the full diameter), meaning faster cuts and less effort.
• Cleaner finish: reduced burrs and smoother hole edges means less rework.
• Extended tool life: carbide tips maintain sharpness over many holes.
• Lower operator fatigue: less feed pressure required — especially helpful on overhead or vertical work.

Safety

• Wear eye, ear and gloves protection; apply cutting fluid to control heat and chip-ejection.
• Ensure magnet is firmly attached and workpiece is stable before drilling; when working overhead or on unstable surfaces, use additional tethering.
• Do not use hammer action; feed steadily and ensure slug is properly ejected to prevent jamming.
• Disconnect power or disable magnet before changing cutters, shanks or pilot pins.
