ANNULAR HOLE CUTTER TCT 83 X 30MM WELD SHANK 31.75MM

Features

• 83 mm diameter — suitable for very large bolt or pipe clearance holes and heavy-structure penetrations.
• 30 mm cutting depth — shallow for large diameter holes in plate or structural material.
• 31.75 mm (1¼″) Weldon shank — two-flat drive ensures secure clamp in magnetic drills or Weldon-arbor setups.
• TCT (tungsten-carbide-tipped) teeth — long-life cutting edges for steel, cast-iron and structural materials.
• Thin-wall, multi-flute body — promotes faster penetration and efficient chip ejection even at large diameters.

Benefits

• Speed in large diameters: only the peripheral ring is removed, making big holes quicker than conventional twist drills for the same size.
• Cleaner finish: fewer burrs and smoother edges reduce rework and improve fit-up.
• Lower feed effort: large diameter but shallow depth keeps feed manageable, especially for on-site setups.
• Robust for heavy duty: TCT tips with Weldon shank provide consistent performance in structural applications.

Extra Information

• Use with a magnetic-base drill or drill-press with compatible 31.75 mm (1¼″) Weldon arbour.
• A pilot pin (sold separately) is required for centring the cutter and slug ejection — verify compatibility with your arbor and setup.
• When drilling stainless steel or harder grades, use appropriate cutting fluid and maintain steady feed to protect the cutter and ensure chip clearance.

Specifications

Safety

• Wear eye, ear and gloves protection; apply cutting fluid to manage heat and assist chip removal.
• Ensure magnet base or clamp is firmly secured and the workpiece stable; use a tether when working overhead or on angled surfaces.
• Do not use hammer or impact drive; maintain 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.
