Fein HSS-Nova 25 63133129051 kernboor 13 mm

For professionals who demand clean, accurate holes in metal, the Fein HSS-Nova 25 63133129051 core drill bit stands apart from ordinary annular cutters. Its optimized cutting geometry and high-speed steel construction deliver fast, precise drilling with excellent concentricity, while the 25 mm cutting depth handles a wide range of sheet and plate work. The Weldon shank ensures a secure, wobble-free connection to magnetic core drilling machines, and the internal coolant supply capability keeps the cutting edge cool for longer tool life. This is a tool built for efficiency and repeatability in demanding workshop environments.

Highlights

• 13 mm cutting diameter for standard hole sizes
• 25 mm maximum cutting depth for thicker materials
• High-speed steel (HSS) with bright finish for durability
• Weldon shank (19 mm) for stable, precise mounting
• Optimized for internal coolant supply to reduce heat
• Efficient chip evacuation for clean, uninterrupted drilling

In daily use

On the job, the HSS-Nova 25 excels in steel, stainless steel, and non-ferrous metals. Its high concentricity means holes are round and on-location, reducing the need for secondary finishing. The bright, uncoated surface resists wear and allows easy inspection of the cutting edge. Whether you are drilling structural steel, fabricating brackets, or performing maintenance, this bit delivers consistent performance. The single-piece package ensures you have the exact tool you need without unnecessary extras.
