DURA 25 Core Drill D.20 mm, TiN-coated, Quick IN (FEIN)

A DURA 25 Core Drill designed for precision metric holemaking with a 20 mm diameter, 25 mm cutting depth and a Quick IN 18 mm shank for efficient workshop use

• HSS construction for high cutting performance
• TiN coating for longer tool life
• 25 mm cutting depth for medium-depth cores
• Quick IN 18 mm shank for fast tool changes

Durable material and coating for reliable uptime

The combination of High-speed steel (HSS) and a TiN coating (titanium nitride) provides a robust balance of toughness and surface hardness. The HSS substrate offers resistance to thermal softening during drilling operations, while the TiN coating reduces friction and improves wear resistance, resulting in extended tool life and more consistent hole quality over a series of uses. This makes the tool a dependable option when consistent repeatability is required on the shop floor.

Fast tool changes and compact, metric dimensions

Equipped with a Quick IN shank (18 mm) the cutter enables rapid mounting and removal from compatible chucks and holders, minimising machine downtime and increasing productivity between operations. The compact overall length of 60 mm, combined with the 20 mm diameter and 25 mm cutting depth, supports precise metric holemaking where space and reach are factors, while ensuring stable handling during machining.

Smooth cutting action and chip control

The design with five cutting edges contributes to a balanced cutting action that reduces vibration and helps produce cleaner core remnants. A defined 25 mm cutting depth permits reliable core extraction within medium-depth tasks, and the tool's metric sizing ensures straightforward integration into existing tool sets. These characteristics aid process stability and reduce the need for rework, benefiting throughput and part quality.

Practical workshop benefits and system compatibility

The drill's Quick IN shank aligns with modular tool-change systems to speed up changeovers and maintain flow in high-rotation environments. The TiN-coated surface also simplifies routine cleaning and inspection by resisting built-up material adhesion. Supplied as a single unit, the tool fits into a systematic tooling approach where repeatable clamping and precise alignment are priorities, supporting efficient maintenance cycles and predictable production planning.

FAQ

What shank does the DURA 25 use and is it compatible with quick-change systems?
The DURA 25 core drill by FEIN (SKU 4149702558NW) features a Quick IN 18 mm shank, designed for compatibility with Quick IN-style holders to enable rapid tool changes and minimise downtime.

What are the main dimensions and drilling depth of this core drill?
The DURA 25 core drill has a 20 mm diameter, an overall length of 60 mm and a 25 mm cutting depth, suited to metric, medium-depth core drilling tasks.

How does the TiN coating benefit operation compared with uncoated variants?
The TiN coating on the FEIN DURA 25 reduces friction and improves surface hardness, which leads to extended tool life and more consistent drilling results over repeated cycles.

How many cutting edges does the tool have and what is the effect?
This core drill is built with five cutting edges, producing a balanced cut with reduced vibration, improving hole finish and chip formation for cleaner core extraction.

Is the DURA 25 suitable for use in a production environment with frequent tool changes?
Yes, the combination of Quick IN shank and robust HSS construction makes the DURA 25 well suited for production settings where fast changeovers and consistent performance are important (FEIN, SKU 4149702558NW).
