RUKO KEB-HSS-TiAlN 41.0 mm Annular Cutter with Weldon Shank

Drilling large-diameter holes in tough metals often means slow progress, excessive heat, and rough edges. The RUKO KEB-HSS-TiAlN 41.0 mm annular cutter solves this by removing only a ring of material, leaving a solid core that ejects cleanly. This hollow design dramatically reduces cutting force and heat, making it ideal for magnetic drilling machines and pillar drills.

Who is it for

Metalworking professionals and serious fabricators who need precise, burr-free holes in steel, stainless steel, cast iron, or non-ferrous metals. If you regularly bore holes up to 55 mm deep in structural steel or heavy plate, this cutter delivers speed and accuracy that twist drills cannot match.

Main features

• High-speed steel body with TiAlN coating for enhanced heat resistance and extended tool life
• 41.0 mm cutting diameter, 55 mm cutting depth
• Weldon 19 mm (3/4") shank for secure mounting in magnetic drills
• Multi-tooth geometry for smooth, vibration-reduced cutting
• Hollow core design ejects slugs automatically, saving time and energy
