Core drill NOVA 25 – 20 mm HSS annular cutter with Weldon shank (FEIN)

The NOVA 25 core drill is a high‑speed steel annular cutter designed for efficient holemaking where consistent hole quality and safe clamping are required

• HSS construction for long life
• Weldon shank 19.05 mm (3/4")
• 20 mm diameter core drill
• 25 mm cutting depth

Precise holes with durable HSS cutting geometry

The annular cutter is manufactured from HSS, offering a balance of hardness and toughness that supports sustained cutting performance. The 5 cutting edges distribute cutting forces evenly, reducing vibration and producing a clean, burr‑reduced bore. For workshop managers and production engineers this means fewer secondary finishing steps and more consistent hole tolerances across a run, which helps to reduce rework and maintain throughput.

Secure clamping and stable machining for repeatability

With a Weldon shank (19.05 mm / 3/4"), the tool locks firmly in place during heavy machining cycles. The shank design minimises slippage in the arbor or holder and promotes torque transfer without compromising concentricity. Combined with the cutter’s overall length of 61 mm, the configuration supports stable machining even when used in common magnetic or drill‑press arbors, improving repeatable results for serial operations.

Short cutting cycles and straightforward tool handling

The defined 25 mm cutting depth and medium overall length reduce chip evacuation distances and operator handling time. The cutter’s geometry enables efficient material removal per pass, shortening cycle times for blind‑through and stopped holes within its depth range. Maintenance is straightforward: the robust construction requires minimal attention between regrinds, supporting continuous productivity in a busy workshop.

Integration into existing workflows and procurement

The tool is supplied as a single unit with a Weldon shank suitable for standard holders; the compact specification eases stocking and tool-change logistics. Technical procurement benefits from clear, machine‑readable specification: 20 mm diameter, 25 mm cutting depth, HSS material, Weldon shank 19.05 mm, and 5 cutting edges. For specialist applications or compatibility checks, technical advisers at Metav Werkzeuge are available to confirm fitment with common arbors and holders.
