NOVA 50 annular cutter — 28 mm, HSS, Weldon shank for robust holemaking

The NOVA 50 annular cutter is a high‑performance HSS core drill designed for efficient metalworking where precise, repeatable holes are required

• High-speed steel (HSS) construction
• Weldon shank 19.05 mm (3/4") for secure clamping
• 28 mm diameter, 50 mm cutting depth
• Seven cutting edges for long service life

Faster holemaking with reduced material removal

Annular cutters remove only the material at the periphery of a hole, which results in significantly less waste and shorter cycle times compared with solid twist drills. The 28 mm diameter and 50 mm cutting depth are optimised for common through‑hole and partial‑depth applications, enabling efficient metal removal while maintaining dimensional control. The geometry of the cutter concentrates cutting forces at the rim, leading to cleaner chips and reduced spindle load, which supports smoother operation in repetitive production environments.

Long life from HSS and precise cutting geometry

Constructed from high‑speed steel (HSS) and featuring seven cutting edges, this cutter combines wear resistance with consistent cutting performance. HSS retains hardness at elevated temperatures, which helps to maintain edge sharpness during demanding runs. The multiple cutting edges distribute wear across the tool, increasing the interval between regrinds and replacements. This extended service life translates into lower tool change frequency and improved uptime in workshop workflows.

Secure clamping and standardised dimensions for easy integration

The Weldon shank 19.05 mm (3/4") offers a robust mechanical connection to compatible chucks and arbor systems, reducing the risk of slippage under heavy feed. Metric specification and clear use of a 3/4" Weldon interface simplify tool selection and stock management across international inventories. The standardised shank and metric labelling make the cutter straightforward to combine with existing holders and adaptors, supporting predictable set‑up times and repeatable clamping accuracy.

Precision depth control and consistent hole quality

With an overall length of 86 mm and a defined 50 mm cutting depth, the cutter provides predictable penetration for controlled holemaking. The rim‑type cutting action reduces radial drift and helps preserve concentricity, resulting in accurate bore diameters and improved fit for press‑fits or threaded operations. The solid HSS construction and precise flute geometry promote uniform chip evacuation, which supports repeatable surface finish and reduces the need for finishing passes.

FAQ

What is the cutting depth of this annular cutter?
The NOVA 50 annular cutter provides a cutting depth of 50 mm, suitable for many partial‑depth and through‑hole operations.

Which shank does the cutter use for clamping?
The tool features a Weldon shank 19.05 mm (3/4"), ensuring secure clamping in compatible holders and arbors.

What material is the tool manufactured from?
The cutter is made from HSS (high‑speed steel), designed for durability and heat resistance during metal cutting.

How many cutting edges does the cutter have and what is the benefit?
The annular cutter has seven cutting edges, which helps to distribute wear and extend the tool's service life while maintaining consistent hole quality.

Can this tool be used with existing arbors and chucks?
Compatibility is achieved via the 3/4" Weldon shank (19.05 mm); the cutter will fit arbors and chucks that accept a Weldon interface and the specified shank diameter.
