Annular Hole Cutter Tct 70 X 30mm Weld Shank 19.05mm

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—check compatibility for your arbor and material thickness.
• When drilling stainless steel or harder grades, apply appropriate cutting fluid and maintain steady feed to protect the cutter and ensure chip clearance.

Features

• 70 mm diameter — for major clearance holes and large-structure penetrations.
• 30 mm cutting depth — shallow depth for large diameter, plate or structural sections.
• 19.05 mm (3/4') Weldon shank — two-flat drive for a secure grip in magnetic drills.
• TCT (tungsten-carbide-tipped) teeth — long-life and high-performance in steel and cast-iron applications.
• Thin-wall, multi-flute design — enables faster penetration and efficient chip ejection even in large diameters.

Benefits

• Large-hole speed: by removing just the periphery, it creates bigger holes faster than twist drills.
• Cleaner finish: fewer burrs mean less cleanup and better fit-up.
• Reduced operator effort: even with large size, the shallow depth keeps feed manageable for vertical or overhead jobs.
• Industrial durability: TCT tips with Weldon interface give reliable performance under tough conditions.

Safety

• Wear eye, ear and gloves protection; apply cutting fluid to control heat and aid chip removal.
• Ensure magnet base or clamp is firmly secured and workpiece stable; use a tether when working overhead or on angled setups.
• Do not use hammer/impact mode; keep steady feed and allow slug to eject cleanly—if feed slows or chatter appears, stop immediately and clear chips.
• Disconnect power or disable magnet before changing cutters, shanks or pilot pins.
