Kernbohrer NOVA 25 – 27 mm HSS core drill, 25 mm cutting depth, Weldon shank (Fein)

The NOVA 25 core drill is a compact, high‑speed steel tool designed for precise 27 mm holemaking where a 25 mm cutting depth and a Weldon shank are required for secure clamping in power drills and holders.

• 27 mm diameter with 25 mm cutting depth
• High‑speed steel body for wear resistance
• Weldon shank 19.05 mm (3/4") for secure clamping
• Suitable for short, precise core drilling tasks

Accurate, repeatable holes for production workflows

The compact core design delivers consistent 27 mm bores with a controlled 25 mm cutting depth, enabling standardised hole sizes across small to medium batches. Built from HSS, the tool balances hardness and toughness so that cutting edges remain effective under typical workshop cutting speeds. For operators unfamiliar with core drills: the cutting depth defines the maximum depth of material removed, while the diameter determines the finished hole size; both values are fixed by the drill geometry and are crucial for jigs and fixtures where repeatability matters. The combination of precise dimensions and a robust body supports predictable process planning and reduced rework.

Secure clamping and improved tool life through shank design

A Weldon shank (19.05 mm / 3/4") allows the drill to be gripped firmly in set‑screw chucks and quick‑change holders, which minimises slippage and runout under load. Reduced slippage means more energy is converted to cutting rather than heat, which contributes to extended service life. The Weldon interface is widely used in industrial drilling applications because it provides a reliable mechanical lock without relying solely on taper friction. Where machine torque and stability are priorities, the shank configuration improves process reliability and reduces the likelihood of surface damage to the workpiece.

Designed for efficiency and straightforward workshop handling

Featuring multiple cutting edges, the core drill is configured to remove material efficiently while maintaining hole integrity. The tool’s overall length of 61 mm keeps the centre of gravity close to the holder, improving balance and reducing vibration in hand‑held and machine applications. For maintenance, the HSS composition permits regrinding of worn cutting lips in many cases, extending usable life and lowering total cost of ownership. Where quick, repeatable results are needed, the drill’s geometry supports fast chip evacuation and straightforward bit changes thanks to the Weldon shank interface.

FAQ

What shank size is required for this core drill?
The core drill uses a Weldon shank of 19.05 mm (3/4"), compatible with set‑screw chucks and quick‑change holders designed for that diameter.

How deep can the drill cut in a single operation?
The specified cutting depth is 25 mm, which defines the material removal depth the drill is designed to perform reliably.

Can the cutting edges be refurbished when worn?
The HSS construction commonly permits regrinding of cutting lips; refurbishment depends on wear pattern and workshop capabilities for precision regrinding.

Is the drill balanced for machine use?
With an overall length of 61 mm and a Weldon shank, the geometry promotes good balance for machine and stable hand‑held applications, reducing vibration when properly clamped.

What does the number of cutting edges mean for performance?
Having 7 cutting edges supports efficient material removal and smoother hole walls, contributing to consistent hole quality and predictable tool behaviour.
