FEIN HSS-Nova 25 broca de coroa 14 mm haste Weldon 63133140051

Drilling large-diameter holes in steel often means dealing with slow progress, excessive heat, and rough edges. The FEIN HSS-Nova 25 annular cutter changes that. Instead of removing the entire hole as chips, it cuts only a ring, leaving a solid core that ejects cleanly. The result is faster cutting, less power consumption, and a finish that needs little rework. This 14 mm cutter is built for magnetic core drilling machines and handles steel up to 900 N/mm² tensile strength.

Who is it for

This cutter is aimed at metalworking professionals, fabricators, and maintenance crews who need precise, repeatable holes in structural steel, sheet metal, or non-ferrous metals. It is equally at home in a production environment or on-site repair work where speed and accuracy matter.

Main features

• High-speed steel (HSS) body with precision-ground cutting edges for clean, burr-free holes.
• Weldon shank (19 mm / 3/4") for secure, wobble-free mounting on magnetic drills.
• 25 mm cutting depth covers most plate and profile thicknesses in a single pass.
• Hollow core design reduces cutting force and heat, extending tool life.
• Multiple cutting edges distribute load evenly for smoother operation.

Tips

Use a suitable cutting paste or spray to keep the cutter cool and prolong edge life. Ensure the magnetic base is firmly seated and the workpiece is clean before starting. After each hole, clear the slug from the cutter to prevent jamming. Store cutters in a dry place, ideally in their original packaging, to protect the cutting edges.
