NOVA 25 core drill (Ø23 mm, HSS, 25 mm cutting depth) by C. & E. Fein

NOVA 25 is a robust HSS core drill with a Weldon shank, designed for precise metal drilling and short-cycle industrial use.

• Core drill Ø23 mm for accurate holemaking
• HSS material for high wear resistance
• 25 mm cutting depth for through and blind holes
• Weldon shank 19.05 mm for secure clamping

Consistent hole quality through engineered cutting geometry

The tool delivers reliable hole dimensions thanks to its optimised flute and cutting-edge arrangement. Manufactured from HSS, the drill combines hardness and toughness so that chip formation and heat resistance are balanced during standard machining cycles. For production planners this means fewer rejects and predictable outcomes; the tool’s defined 25 mm cutting depth allows controlled engagement of the workpiece, reducing the risk of chatter and improving concentricity.

Secure clamping for repeatable performance

The Weldon shank with a 19.05 mm diameter ensures positive drive engagement in holders and chucks designed for Weldon tooling. This clamping method prevents rotation slippage under higher torque and provides a stable interface for repetitive operations. Because the shank form is standardised, replacement is straightforward and the toolholder inventory remains compact, supporting rapid changeovers and minimal downtime.

Durable design that supports efficient workflows

With six cutting edges and a construction aimed at extended life, the core drill offers high wear resistance in many metalworking contexts. The combination of solid HSS and precise machining of the working flutes reduces regrinding frequency and supports continuous use in small-batch to medium-volume production. Where tool life and process stability matter, this core drill contributes to cost-effective machining by lowering the frequency of tool interventions.

FAQ

What materials is the NOVA 25 core drill suitable for?
The NOVA 25 core drill, made from HSS, is intended for general metalworking applications where HSS performance is appropriate; specific suitability depends on the workpiece material and machining parameters.

What is the shank size and clamping requirement?
The tool features a Weldon shank of 19.05 mm (3/4"), requiring a Weldon-style holder or chuck with the matching clamping arrangement for positive drive.

How deep can the NOVA 25 cut in a single pass?
The specified cutting depth is 25 mm, which defines the effective engagement length for controlled holemaking and process planning.

How many cutting edges does the tool have and what does that mean?
The core drill has six cutting edges; this contributes to smoother cutting action and improved chip evacuation compared with fewer-edge designs in similar diameters.

Is the NOVA 25 suitable for blind holes?
Yes, the 25 mm cutting depth allows both through-holes and blind-hole operations within that axial limit.
