NOVA 25 Core drill 21 mm — HSS, 25 mm cutting depth, Weldon shank (FEIN)

NOVA 25 is a compact HSS core drill designed for precise 21 mm holes with a controlled 25 mm cutting depth and a Weldon 19.05 mm shank for stable clamping in industrial holders.

• HSS material for long tool life
• 25 mm cutting depth for precise cores
• Weldon shank 19.05 mm for secure clamping
• Six cutting edges for efficient metal removal

Precision and durability for daily workshop use

The HSS construction delivers consistent cutting performance and high tool life, especially under repetitive conditions often found in workshops and light industrial environments. With a 21 mm diameter and a defined 25 mm cutting depth, the tool produces uniform core holes that minimise rework and inspection time. The combination of hardened HSS and a multi-edge geometry reduces rubbing and heat build-up; this translates into longer intervals between tool changes and a more predictable production output.

Secure mounting and vibration control for better hole quality

A Weldon shank (19.05 mm) ensures rigid fixation in compatible tool holders and chucks, significantly reducing torsional play during operation. The solid connection improves concentricity and stability, which is particularly important when using smaller cutting depths where surface finish and dimensional accuracy matter. The tool’s six cutting edges distribute cutting forces, lowering the risk of chatter and delivering a cleaner bore with fewer burrs, thereby reducing downstream finishing operations.

Designed for efficient handling and straightforward integration

With an overall length of 61 mm and a practical shank format, the core drill integrates easily on vertical drill presses and powered holders that accept Weldon shanks. The compact geometry supports fast tool changes and straightforward set-up procedures on the shop floor, keeping machine downtime to a minimum. The defined geometry simplifies feed and speed calculations and helps maintain consistent cycle times in batch production.

Quality assurance and application guidance for confident purchasing

Manufactured from HSS and finished for reliable workshop use, the tool reflects a focus on repeatability and service life rather than one-off performance. Clear technical parameters — diameter, cutting depth and shank size — make it straightforward to match the tool to existing holders and machining setups. For complex applications or to confirm compatibility with specific holders, the seller’s technical advisors can provide tailored recommendations and ensure the selected tool meets operational demands.

FAQ

What is the exact cutting depth of the NOVA 25 core drill?
The NOVA 25 core drill provides a defined 25 mm cutting depth, allowing predictable hole depth without secondary operations.

Which shank size is required for clamping this core drill?
This tool uses a Weldon shank of 19.05 mm (3/4"), suitable for Weldon-type holders and chucks that accept that shank diameter.

How many cutting edges does the tool have and what is the advantage?
The core drill has six cutting edges; this distributes cutting forces, reduces vibration and improves hole finish.

Is the drill made from high-speed steel?
Yes, the tool is manufactured from HSS, offering wear resistance and reliable performance under workshop conditions.
