NOVA 50 core drill, 22 mm — HSS body with Weldon shank by C. & E. Fein GmbH

A NOVA 50 core drill designed for precise, repeatable 22 mm core holes in metalworking and industrial fabrication, featuring a short overall length and a robust Weldon shank for secure clamping

• HSS construction for extended service life
• Weldon shank 19.05 mm (3/4")
• 22 mm diameter, 50 mm cutting depth
• Six cutting edges for precise core removal

Reliable cutting performance for demanding workflows

The core drill is built from HSS, providing a balance of toughness and wear resistance suited to repeated drilling operations. With a 22 mm cutting diameter and a 50 mm cutting depth, the geometry allows efficient removal of material while maintaining hole quality. The tool’s six cutting edges reduce vibration and lower the risk of jagged cores, which helps maintain consistent cycle times in a production setting. The relatively compact 86 mm overall length keeps the centre of gravity close to the holder, aiding stability in high-torque applications.

Secure clamping and compatibility with industrial holders

The Weldon shank 19.05 mm (3/4") is a common industrial standard and enables firm, positive clamping in Weldon-style tool holders. This design minimises slippage under load and improves torque transmission compared with plain-shank alternatives, which is especially important for deep or interrupted drilling. Using a Weldon-holder system simplifies tool changes on machines equipped for quick swaps and helps to reduce downtime between operations.

Clear advantages for repeatable holemaking and maintenance

Metric dimensions and straightforward geometry make the drill easy to integrate into existing machining routines. The HSS construction permits resharpening to extend service life where appropriate, offering a cost-effective lifecycle compared with disposable alternatives. The compact design and six-flute cutting arrangement also promote orderly chip formation and evacuation, which supports consistent surface finish and accurate core diameters over repeated cycles.

Application fit and process benefits

Intended for industrial metalworking tasks, the tool’s balanced specifications make it suitable for tasks that prioritise reliability and repeatability. The combination of 22 mm diameter and 50 mm cutting depth addresses common fabrication requirements while the short overall length contributes to enhanced stiffness during drilling. Where secure clamping and quick tool changes are required, the Weldon shank configuration is advantageous for preserving process stability and reducing rework.

FAQ

Which tool holders are compatible with this core drill?
The core drill uses a Weldon shank 19.05 mm (3/4"), so it is compatible with standard Weldon-style holders and chucks designed for 3/4" Weldon clamping.

Can the drill be resharpened to extend service life?
Yes, the HSS construction of the NOVA 50 core drill permits resharpening by qualified tool service providers to restore cutting geometry and extend service life.

What size and depth does the tool produce?
The tool produces a 22 mm hole with a cutting depth of 50 mm; the overall length of the bit is 86 mm, offering a compact solution for through and partial-depth cores.

How does the six-edge design affect hole quality?
The six cutting edges reduce vibration and help form clean cores, resulting in improved surface finish and dimensional consistency compared with fewer-flute designs.

Is the product suitable for automated drilling setups?
The Weldon shank and metric dimensions of this core drill make it suitable for integration into many automated and manual drilling setups that accept 3/4" Weldon tooling.
