Fein HSS-Nova 50 Τρυπάνι πυρήνα 22 mm Στέλεχος Weldon 63133219052

When cutting deep, clean holes in steel, standard twist drills quickly reach their limits. The Fein HSS-Nova 50 core drill bit changes that: its annular cutter design removes only a ring of material, leaving a solid slug instead of grinding away the entire bore. The result is dramatically faster drilling, lower power consumption, and a hole that is rounder and more accurate than a conventional drill can achieve. Built from high-speed steel with optimized cutting geometry, this 22 mm cutter is a workhorse for metal fabrication, installation, and maintenance tasks.

Highlights

• Annular cutter design for fast, efficient drilling in steel and non-ferrous metals
• High-speed steel (HSS) body with bright, uncoated finish for long tool life
• 22 mm cutting diameter and 50 mm cutting depth for deep holes
• Weldon shank (19 mm / 3/4 inch) for secure, wobble-free mounting in magnetic core drills
• Optimized for internal cooling – ideal for use with cutting fluid
• Excellent chip removal for clean, burr-free holes

In daily use

The HSS-Nova 50 is a direct fit for FEIN magnetic core drills and any machine with a 19 mm Weldon holder. Its 50 mm cutting depth covers most structural steel, plate, and profile work. The annular cutting principle means less heat, less wear, and less effort – even in tough materials. For best results, use a suitable cutting oil or emulsion and let the tool do the work. The bright finish helps prevent corrosion and makes it easy to inspect the cutting edges.
