NOVA 50 annular cutter – 35 mm, HSS with Weldon shank (FEIN)

The NOVA 50 is an HSS annular cutter designed for precision metalworking and industrial holemaking, suitable for use in magnetic drills and compatible arbors for efficient 35 mm hole production.

• HSS construction for high wear resistance
• Weldon shank 19.05 mm (3/4") for secure clamping
• 50 mm cutting depth for efficient holemaking
• Designed for metric systems and metalworking

Precision cutting for consistent hole quality

The annular cutter is manufactured from HSS, which provides a balanced combination of toughness and edge retention for industrial use. With 8 cutting edges and a defined cutting depth of 50 mm, the tool removes material efficiently while keeping heat buildup manageable. This means fewer reworks and more predictable production cycles, especially in repetitive tasks such as structural fabrication or site-based drilling. The geometry and material choice are geared towards stable performance across common steels and general metalwork.

Secure mounting and torque transfer with the Weldon shank

Equipped with a Weldon shank 19.05 mm (3/4"), the cutter offers secure clamping and clearance for reliable torque transfer during heavy-duty operation. The shank format is a standard for many arbors and magnetic drilling units, reducing the need for additional adaptors and minimising runout. Secure clamping contributes directly to tool life and hole precision, translating into less downtime and fewer scrap parts in production environments.

Designed for efficient workshop workflows

A total length of 86 mm combined with the 35 mm bore diameter makes this cutter a compact solution for confined setups while still allowing a practical working reach. Metric dimensions throughout simplify tool selection and inventory management in facilities that standardise on metric tooling. The construction emphasises long service life, so maintenance intervals are extended and replacement frequency is reduced, supporting continuous operation on the shop floor.

Practical benefits and suitable applications

The tool is particularly appropriate for metal fabrication, maintenance teams and mechanical workshops that require fast, clean holes in ferrous materials. As an annular cutter it produces less swarf than twist drills when creating blind or through-holes of the specified diameter, which can speed up chip removal and post-process cleaning. The tool’s features support efficient cycle times and integration into established drilling workflows without complex adjustments.

FAQ

What materials can be machined with this annular cutter?
The annular cutter is made of HSS and is suitable for general metalworking tasks; it is primarily intended for use in common ferrous materials and structural steels.

Which machines is the cutter compatible with?
The Weldon shank 19.05 mm (3/4") enables compatibility with many magnetic drills and standard arbors that accept a 3/4" Weldon fitment, offering reliable clamping and torque transfer.

Is the 50 mm cutting depth sufficient for through-holes?
A 50 mm cutting depth allows efficient production of through-holes and blind holes within that depth; for deeper requirements, alternative cutters with greater reach should be considered.

Can the cutter be resharpened?
Yes, tools made from HSS can typically be resharpened by a qualified service; resharpening extends the useful life of the cutter while preserving bore quality.

What does the SKU 4149702673NW refer to?
SKU 4149702673NW identifies this specific NOVA 50 annular cutter configuration (35 mm diameter, 50 mm cutting depth, Weldon shank) for ordering and stock control.
