For metalworking professionals tackling steel plates, beams, or pipes on a magnetic core drilling machine, the Fein HSS-Nova 25 annular cutter delivers clean, precise 16 mm holes with a 25 mm cutting depth.

Why choose it

Fein's HSS-Nova 25 line is built for general-purpose metal drilling where accuracy and tool life matter. The precision-ground flutes and bright finish reduce friction, while the annular design removes only a ring of material, saving time and energy compared to twist drills. The 19 mm Weldon shank is the industry standard for magnetic drills, so it drops right into your existing setup.

Ideal use cases

• Drilling holes in structural steel on construction sites
• Creating openings for cables or pipes in metal enclosures
• Fabrication work in workshops and maintenance departments
• On-site repairs where a magnetic drill is available

Good to know

This cutter is uncoated, which is typical for HSS annular cutters and allows for easy resharpening. Use a suitable cutting fluid or internal coolant for best results, and ensure your magnetic drill has a 19 mm Weldon arbor. The slug is ejected automatically after each cut, so keep the work area clear.
