NOVA 50 annular cutter, 25 mm diameter, HSS with Weldon shank

A NOVA 50 annular cutter engineered for precise 25 mm holes with a 50 mm cutting depth, featuring a Weldon 19.05 mm (3/4") shank for secure clamping and reliable performance.

• Solid HSS construction for long tool life
• Weldon shank 19.05 mm (3/4") for secure clamping
• 25 mm diameter with 50 mm cutting depth
• Seven cutting edges for fast metal removal

High-performance cutting for efficient production

The HSS body and seven cutting edges combine to deliver rapid material removal while maintaining dimensional accuracy. The multi-edge geometry lowers cutting forces and distributes wear, which translates into longer intervals between regrinds and fewer tool changes. For production environments focused on throughput, this design supports a smoother workflow by reducing cycle interruptions and maintaining consistent hole quality. The 50 mm cutting depth allows for through-holes and substantial partial-depth operations without multiple passes, enhancing process efficiency.

Secure mounting and compatibility with standard clamping systems

A Weldon shank 19.05 mm (3/4") ensures positive locking in Weldon-style holders and chucks, minimising slippage under load and enabling safe torque transmission. The familiar shank diameter aligns with common magnetic drill and machine spindles that accept Weldon tooling, simplifying tool change routines and reducing adaptor requirements. Clear, metric dimensions alongside the imperial shank reference facilitate straightforward integration into mixed-equipment workshops and reduce setup time.

Precision, handling and dimensional clarity

With a nominal 25 mm diameter and an overall length of 86 mm, this annular cutter balances rigidity and reach for controlled drilling cycles. The metric specification of both cutting depth and diameter supports accurate process planning and repeatability. The firm geometry of the cutter contributes to consistent hole tolerances and a clean bore finish, which in many cases reduces the need for secondary deburring or finishing operations.

Durability, maintenance and practical benefits

Constructed from HSS, the cutter offers a proven compromise between toughness and wear resistance for a range of ferrous and non-ferrous materials where high-speed steels are appropriate. The cutter’s geometry and material choice mean predictable wear behaviour and straightforward reconditioning when required. For workshops seeking to limit tool inventory while maintaining quality, the combination of a standard Weldon shank and metric cutting parameters delivers a versatile, serviceable solution that fits into established maintenance routines.

FAQ

What materials is this annular cutter intended for?
The NOVA 50 annular cutter, made from HSS, is designed for typical metalworking applications where high-speed steel tooling is appropriate; material suitability should be confirmed against specific workpiece requirements.

Which holder or chuck is required for secure clamping?
The cutter fits Weldon-style holders with a 19.05 mm (3/4") grub-screw arrangement; the Weldon shank ensures secure clamping in compatible chucks and adaptors.

What is the effective drilling depth and overall reach?
This tool provides a 50 mm cutting depth with an overall length of 86 mm, offering a balance between reach and rigidity for through-holes and partial-depth drilling operations.

Is regrinding possible and how does edge count affect life?
With seven cutting edges the wear is distributed over multiple cutting faces, which extends service life; regrinding is feasible subject to workshop capability and standard HSS reconditioning practices.
