NOVA 50 21 mm Annular Cutter (Weldon shank) – FEIN

The NOVA 50 is a high-speed-steel annular cutter engineered for efficient, metric deep-hole cutting in metalworking applications with a 21 mm diameter and 50 mm cutting depth

• HSS construction for longevity
• Weldon shank 19.05 mm (3/4")
• 50 mm cutting depth
• Six cutting edges for smooth cuts

Faster, more efficient holemaking with durable cutting geometry

The annular cutter delivers rapid material removal thanks to its HSS composition and optimised cutting geometry. With six cutting edges, chip formation is controlled and the power demand on the machine is reduced, which shortens cycle times in production runs. The result is improved throughput and consistent hole quality, making this tool suitable for repetitive tasks where machining efficiency is the priority.

Secure clamping and compatibility with magnetic drills and arbors

A robust Weldon shank of 19.05 mm (3/4") ensures positive locating in standard toolholders and magnetic drill arbors, preventing slippage under torque. The shank form simplifies changeover and supports concentricity during drilling, which helps to maintain bore straightness and surface finish. This stability is particularly relevant when cutting through thicker metal sections where reliable clamping is essential.

Built for longevity to reduce downtime and maintenance

Constructed from HSS, the cutter offers high wear resistance and a predictable service life under normal operating conditions. The tool’s 50 mm cutting depth paired with an overall length of 86 mm balances reach and rigidity, reducing the need for frequent tool changes. For workshops aiming to lower unplanned stoppages, this equates to fewer interruptions and smoother production planning.

Metric design and practical handling for workshop use

With a clear metric specification set and 21 mm diameter, the cutter integrates readily into metric tooling systems and machining processes. The combination of a compact overall length and the Weldon shank makes handling straightforward while supporting precise alignment in jigs and fixtures. This tool is a practical choice for fabricators and maintenance teams seeking reliable, metric annular cutters for routine and specialised holemaking.
