NOVA 50 annular cutter (16 mm) by FEIN — 50 mm cutting depth, Weldon shank

The NOVA 50 annular cutter is a precision core drill designed for efficient metal hole production with a 50 mm cutting depth and a 3/4" Weldon shank for secure arbor mounting

• High-speed steel construction for durability
• Weldon shank 19.05 mm (3/4") for secure clamping
• 50 mm cutting depth for deep bore applications
• Five cutting edges for efficient material removal

Faster, more economical holemaking with a precision cutter

The annular cutter offers a clear efficiency advantage over solid twist drills when producing clean, precise bores. Made from HSS, this cutter combines material hardness with toughness to deliver a long service life under intermittently heavy loads. The five cutting edges reduce cutting forces per tooth, improving chip evacuation and reducing strain on the drive system. As a result, cycle times are reduced and consumable costs fall, which supports a smoother production flow in small series or workshop environments.

Reliable mounting and tool stability for consistent results

A Weldon shank (19.05 mm / 3/4") ensures positive axial clamping in compatible arbors and drill chucks, eliminating slippage during high-torque operations. The specified shank format makes the cutter suitable for many standard arbour mounts and magnetic drill interfaces that accept Weldon clamping. The 16 mm diameter and the 86 mm total length provide a compact, well-balanced tool geometry that promotes stability and concentricity during drilling, resulting in cleaner hole surfaces and consistent diameters.

Practical design that reduces rework and maintenance

With a 50 mm cutting depth this core drill removes the need for multiple passes in many through-hole tasks, while the metric dimensions and familiar HSS chemistry simplify tool selection and stock keeping. The cutter’s construction targets durable service life, so less frequent replacement is needed compared with lower-grade alternatives. For maintenance, standard sharpening and inspection routines for annular cutters apply; the geometry and number of cutting edges aid predictable regrinding intervals and consistent return-to-spec performance.

Who benefits and how to integrate the cutter

This tool is aimed at industrial workshops, maintenance departments and specialist fabricators seeking dependable holemaking with minimal setup overhead. Its Weldon interface and HSS construction make it well suited for integration into existing hole-cutting workflows with compatible arbors and magnetic or portable drilling systems. Specifying a cutter with these core features can streamline inventory, reduce machining time per hole and improve overall throughput on repetitive drilling tasks.

FAQ

What shank size does the cutter use and which arbors fit it?
The annular cutter features a 19.05 mm (3/4") Weldon shank, which fits standard Weldon arbors and chucks designed for that shank size.

What is the maximum cutting depth of the tool?
The tool offers a 50 mm cutting depth, allowing single-pass holemaking for many common through-hole applications.

From which material is the cutter manufactured?
The cutter is manufactured from HSS (high-speed steel), providing a balance of hardness and toughness for metalworking.

How many cutting edges does this cutter have and what is the benefit?
The cutter has five cutting edges, which improves chip removal and reduces cutting forces per edge for smoother drilling and longer tool life.

Is the cutter suitable for workshop and industrial use?
Yes; the NOVA 50 core drill is designed for robust workshop and industrial holemaking where reliable repeatability and a Weldon shank interface are required.
