NOVA 25 annular cutter — HSS, 34 mm diameter, 25 mm cutting depth (C. & E. Fein GmbH)

The NOVA 25 is an HSS annular cutter designed for efficient holemaking in metalworking applications, featuring a robust Weldon shank for secure mounting and a 25 mm effective cutting depth for fast through-hole and blind-hole production

• HSS for extended wear resistance
• Weldon shank 19.05 mm for secure mounting
• 25 mm cutting depth for fast holemaking
• 34 mm diameter for standard hole sizes

Consistent cutting life from high-speed steel construction

The core advantage of the HSS material is sustained performance under repetitive use: the high-speed steel composition provides wear resistance that keeps the cutting geometry stable over many cycles, which reduces dressing and replacement frequency. Where material knowledge is limited, HSS can be explained as an alloy engineered to retain hardness at elevated temperatures, so the cutter remains sharp during continuous drilling. The result is fewer interruptions and improved process reliability thanks to its long tool life and stable edge retention.

Secure, vibration-reducing clamping for accurate holes

A decisive practical benefit is the Weldon shank 19.05 mm, which enables positive clamping in Weldon-style holders and magnetic drills. This shank form reduces slippage and minimises runout, translating to straighter holes and less rework in subsequent processes. The shank dimension is a standard interface that supports fast tool changes and reliable torque transfer, meaning set-up time is reduced and machine uptime is increased without sacrificing concentricity.

Precise hole geometry with controlled cutting depth

With a 34 mm diameter and a defined 25 mm cutting depth, the cutter delivers predictable hole geometry that helps maintain part tolerances. The specified total length of 61 mm supports stable engagement while the annular design removes a ring of material rather than the full core, lowering chip volume and cutting forces. The cutter’s configuration of eight cutting edges distributes load and improves chip formation, giving a consistent finish and less mechanical stress on the host machine.

Workshop-ready design for production and maintenance

Built by C. & E. Fein GmbH, this annular cutter is aimed at professional workshops that require dependable holemaking tools. The combination of HSS construction, robust shank form and a compact overall length ensures compatibility with common magnetic drilling rigs and machine holders. For procurement and inventory planning, the clear technical specification supports quick integration into tool lists and maintenance schedules, contributing to an uninterrupted workflow and predictable service intervals.

FAQ

What machines are compatible with this annular cutter?
The NOVA 25 annular cutter fits machines and magnetic drills that accept a Weldon shank 19.05 mm mounting; compatibility depends on the chuck or arbor design used in the drilling unit.

Can the cutter produce through-holes and blind holes?
Yes, the cutter’s 25 mm cutting depth allows both blind-hole and shallow through-hole applications within that axial range when used with appropriate machine settings.

Which materials is the cutter best suited for?
The HSS construction of this annular cutter provides general-purpose performance across many ferrous workshop applications; material-specific limits should be checked against machine speed and feed recommendations.

How does the annular design affect chip removal?
The annular cutter removes a ring of material rather than the full core, reducing chip volume and cutting forces; this improves chip evacuation and decreases the load on the drilling machine.

Is the Weldon shank standard size indicated in the SKU?
The SKU 8000380300NW corresponds to the NOVA 25 with a Weldon shank 19.05 mm and the specified dimensions and features as listed above.
