NOVA 25 annular cutter (19 mm) – HSS with Weldon shank by C. & E. Fein

NOVA 25 is an HSS annular cutter engineered for efficient core drilling in industrial metalworking and maintenance applications

• Solid HSS construction
• Weldon shank 19.05 mm (3/4")
• 25 mm cutting depth
• Five cutting edges for smooth cores

Consistent, repeatable bores that reduce rework

The annular cutter is designed to deliver precise bores with consistent diameters and clean edges. Its five cutting edges distribute cutting forces evenly, which reduces vibration and the risk of tapering in the hole. A nominal diameter of 19 mm combined with the cutter geometry produces burr-minimised results that lower finishing effort and shorten cycle times in series production or maintenance tasks. This stability supports predictable process planning and higher first-pass yield.

Secure clamping and durable performance for tougher tasks

The Weldon shank (19.05 mm / 3/4") provides secure axial and rotational clamping in Weldon-style holders and arbors, ensuring concentricity and safe driving under load. Made from high-speed steel (HSS) and optimised for high stand time, the tool sustains performance across repeated operations and abrasive conditions. The overall length of 61 mm with a 25 mm effective cutting depth is balanced for both accessibility and rigidity, offering a dependable choice where tool life and retention of geometry are priorities.

Efficient chip removal and practical workshop benefits

Annular cutting removes a core rather than producing a full-diameter slug, which improves material removal rates and reduces the power demand on the machine. The shorter contact length through the workpiece lowers heat build-up, while the cutter geometry supports controlled chip formation and evacuation. These factors contribute to faster setups and fewer interruptions, making the tool suitable for production lines, fabrication shops and on-site maintenance where throughput and reliability matter.

Compatibility and workshop integration

The cutter’s Weldon shank format and HSS material mean straightforward integration into existing tool inventories that use Weldon holders or compatible adaptors. Its compact dimensions and standardised shank diameter simplify tool changes and minimise the need for special fixtures. For workshops looking to standardise on robust core-drilling solutions, this tool provides a practical balance between durability and operational convenience.

FAQ

What materials is this annular cutter suitable for?
The NOVA 25 annular cutter, made from HSS, is intended for common metalworking tasks; its geometry and robust material promote effective cutting in a range of ferrous workshop applications.

How does the Weldon shank benefit workshop use?
The Weldon shank (19.05 mm / 3/4") secures the cutter positively in Weldon-style holders and arbors, improving concentricity and reducing slippage during high-torque operations.

Can the cutter be re-sharpened or reused?
The HSS construction allows for reconditioning in many cases; re-sharpening should be performed by a qualified service to maintain original geometry and the five-edge balance.

Which machines are compatible with this core drill?
The tool fits Weldon-holder-equipped drilling stations and magnetic drills with suitable Weldon adaptors; the shank format is a standard for secure mounting in industrial settings.

What makes this cutter efficient compared with twist drills?
As an annular cutter, it removes a ring-shaped core rather than the full material column, yielding faster metal removal, lower thrust forces and cleaner hole edges compared with conventional twist drills.
