Fein HSS-Nova 25 broca de corona 12 mm mango Weldon 63133119051

The Fein HSS-Nova 25 annular cutter stands apart through its precision-ground multi-tooth geometry, engineered for clean, burr-free core drilling in steel and non-ferrous metals. Unlike conventional twist drills, this cutter removes only the perimeter material, dramatically reducing power consumption and machining time while extending tool life. Its 12 mm cutting diameter and 25 mm cutting depth make it ideal for creating accurate holes in sheet metal, profiles, and pipes up to 25 mm thick.

Highlights

• High-speed steel (HSS) body with bright finish for durability and corrosion resistance.
• Weldon shank 19 mm (3/4") for secure mounting in magnetic core drilling machines.
• Internal coolant delivery ensures efficient chip evacuation and heat dissipation.
• Multi-tooth cutting geometry delivers smooth, precise holes with minimal burr.
• Precision ground for consistent performance and long service life.

In daily use

On the job site, the HSS-Nova 25 excels in fabrication, maintenance, and construction tasks. Its compact design allows access in tight spaces, while the 25 mm depth capacity covers most common structural steel thicknesses. The cutter works efficiently with cutting oil or emulsion, and the internal coolant channels keep the cutting edge cool, preventing premature wear. Whether drilling anchor holes, conduit entries, or alignment pins, this cutter delivers repeatable accuracy.
