NOVA 50 annular cutter D 34 mm (Weldon shank) by C. & E. Fein

The NOVA 50 annular cutter is a high‑performance core drill designed for fast, precise holemaking in metalworking applications where robust clamping and sustained cutting life are required

• HSS construction for high wear resistance
• Weldon shank 19.05 mm (3/4") for secure clamping
• 50 mm cutting depth for deeper hole cutting
• Eight cutting edges for fast chip removal

Consistent durability and cutting performance

Constructed from HSS, this annular cutter offers high durability and predictable wear behaviour under repeated use. The tool’s geometry with eight cutting edges promotes smoother engagement with the workpiece and reduces vibration, which in turn supports consistent hole diameter and surface finish. For production environments where repeatability matters, the combination of tool material and multi‑edge cutting significantly lowers the frequency of regrinds and replacements, helping to maintain throughput and reduce downtime.

Secure fixation and rapid metal removal

The Weldon shank 19.05 mm (3/4") ensures a rigid, slip‑free connection to standard toolholders, enabling higher feed rates and safer operation when compared with straight‑shank alternatives. The annular design removes a solid core rather than pulverising the entire volume, so chip load is reduced and power demand is kept efficient. With a 50 mm cutting depth, the cutter is suitable for a range of through and blind holes in common workshop tasks while maintaining stable cutting conditions.

Simple integration with common holders and machines

Metric dimensions and a 34 mm diameter make this cutter compatible with widely used holders and magnetic drilling setups that accept a 3/4" Weldon shank. The 86 mm total length provides sufficient reach while keeping overhang minimal, which helps to preserve concentricity during drilling. This physical compatibility reduces setup time and simplifies tool management in mixed fleets, allowing rapid changeovers between jobs without complex adapters.

Practical applications and workflow advantages

As a precision annular cutter manufactured by C. & E. Fein GmbH, the NOVA 50 is built for routine fabrication tasks where hole quality, tooling life and reliable clamping are priorities. Use on metal structures, machine frames and assembly components benefits from the cutter’s efficient chip evacuation and robust shank fixation, delivering clean, true holes with fewer passes. When paired with the appropriate coolant and correct feed speeds, the cutter contributes to lower cycle times and reduced secondary operations.

FAQ

What shank size does this annular cutter require?
The cutter uses a Weldon shank 19.05 mm (3/4"), which fits standard Weldon holders and magnetic drill adapters designed for that shank dimension.

What is the usable cutting depth of the tool?
The tool provides a 50 mm cutting depth, enabling efficient drilling of medium‑depth through and blind holes with a single pass when set up correctly.

Which material is the cutter made from and what does that mean for wear?
Made from HSS, the cutter offers predictable wear characteristics and good toughness, which supports longer service life in general metalworking operations compared with standard carbon steels.

How many cutting edges does the cutter have and why is that advantageous?
The annular cutter features eight cutting edges, which improves chip formation and reduces cutting forces, resulting in smoother holes and faster material removal.

Is the cutter suitable for use with magnetic drill presses?
Yes, the 3/4" Weldon shank and the cutter’s total length make it compatible with many magnetic drill presses and holders that accept Weldon‑shank annular cutters.
