Annular Hole Cutter Hss 31 X 55mm Weld Shank 19.05mm

Features

• 31 mm diameter — suitable for larger bolts, sleeves and clearance holes.
• 55 mm cutting depth — handles substantial plate thicknesses and multi-stack setups.
• 19.05 mm (3/4') Weldon shank — secure two-flat drive for use in magnetic drills and arbors.
• HSS (high-speed steel) body — durable construction for metal drilling applications.
• Thin-wall, multi-flute geometry — faster penetration, efficient chip removal and reduced machine load.

Benefits

• Faster drilling: removes only the ring of material rather than full core, reducing time per hole.
• Cleaner finish: less burr-formation means less cleanup and better fit for bolt/sleeve applications.
• Reduced effort: lower feed pressure required, especially helpful on vertical or overhead drilling.
• Versatile tool life: HSS material and Weldon shank design give longevity and reliable performance for industrial use.

Extra Information

• Designed for use with magnetic-base drills or drill presses fitted with a 19.05 mm (3/4″) Weldon shank arbor.
• A pilot pin (sold separately) is required for centring the cutter and ejecting the slug—confirm compatibility with your arbor.
• When drilling stainless steel or harder materials, apply proper cutting fluid and maintain a steady feed to protect the cutter and ensure efficient chip evacuation.

Specifications

Safety

• Wear eye, ear and gloves protection; use appropriate cutting fluid to control heat and assist chip removal.
• Ensure the magnet or base is firmly clamped to a flat work surface; confirm workpiece stability and use a tether if drilling overhead or on angled surfaces.
• Do not use hammer or impact mode; feed steadily and allow the slug to eject naturally. If feed slows or chatter begins, stop and clear chips immediately.
• Disconnect power or disable magnet before changing cutters, pilot pins or shanks.
