NOVA 50 core drill D.23 mm Weldon – FEIN

The NOVA 50 core drill D.23 mm is an HSS annular cutter designed for efficient metal holemaking with a 50 mm cutting depth and a 19.05 mm (3/4") Weldon shank for secure machine clamping

• HSS construction for high wear resistance
• Weldon shank 19.05 mm (3/4") for secure clamping
• 50 mm cutting depth for standard core holes

Faster, cleaner holes with reduced material removal

Annular cutters remove only the material at the hole perimeter rather than the whole core, which makes them faster and less demanding on the machine than conventional twist drills. Made from HSS, this cutter maintains sharp cutting edges under typical workshop conditions, producing clean 23 mm bores with minimal burr formation. The specified 50 mm cutting depth enables through-holes and short blind bores while keeping cycle times low, helping small-batch production and maintenance tasks run more efficiently.

Secure clamping and consistent tool life for repeat operations

The Weldon shank design with a diameter of 19.05 mm (3/4") provides positive axial and rotational fixation in compatible arbors and holders, reducing slippage under load. With 6 cutting edges, the geometry balances cutting performance and longevity: each revolution distributes wear, supporting a long service life in steel and general workshop steels. The combination of HSS material and robust shank design delivers predictable performance, which is essential for repeat drilling sequences and reduces rework rates in fabrication and maintenance operations.

Seamless workshop integration and simple maintenance

With an 86 mm overall length and metric dimensions throughout, the cutter fits standard holders and arbor systems used in many metalworking shops. The modest overall length keeps the tool rigid in retrofit setups, improving concentricity and hole quality. Handling and regrinding procedures are straightforward for trained staff: worn cutters may be reground by specialist services to restore geometry, extending tool life and lowering total cost of ownership. The single-piece packaging unit supports immediate deployment for repair jobs or integration into production lines.

FAQ

What materials is this cutter suited for?
The NOVA 50 core drill is made from HSS and is designed primarily for general metalworking applications, providing reliable performance in common steels and workshop-grade materials.

How is the cutter secured in the machine?
Clamping is achieved via the Weldon shank (19.05 mm / 3/4"), which ensures secure fixation in appropriate arbors and holders to prevent rotation and axial movement during cutting.

Can the NOVA 50 produce blind holes as well as through-holes?
Yes, the specified 50 mm cutting depth allows both through-holes and short blind bores while maintaining hole quality and efficient chip evacuation.

Is regrinding possible to extend tool life?
Worn HSS annular cutters can often be reground by qualified tool services to restore the original geometry, helping to extend overall service life and reduce replacement frequency.
