NOVA 25 core drill (annular cutter) by C. & E. Fein GmbH — 35 mm diameter, 25 mm cutting depth

A NOVA 25 core drill engineered for rapid, clean hole-making in metalworking applications; the annular cutter design concentrates material removal in the periphery for faster feed rates and reduced power demand.

• HSS construction for extended tool life
• Weldon shank 19.05 mm (3/4")
• 35 mm diameter, 25 mm cutting depth
• 8 cutting edges for stable cutting

Faster, more economical holemaking thanks to focused cutting geometry

The annular cutter is made from HSS, offering a balance of hardness and toughness that supports consistent performance under repeated use. With a 35 mm diameter and a 25 mm effective cutting depth, the geometry reduces material removal compared with full-bore drills, which in practice lowers energy consumption and shortens cycle times. The 8 cutting edges distribute cutting forces evenly, leading to reduced vibration and a more predictable finish. This technical setup translates into measurable productivity gains for busy workshops and production lines.

Secure clamping and repeatable positioning with a Weldon shank

The tool features a Weldon shank, specified at 19.05 mm (3/4"), designed for positive clamping in magnetic drill chucks and compatible holders. This shank style aids accurate axial alignment and prevents slippage under high torque, which is particularly valuable when performing consecutive holes or long production runs. The combination of a compact overall length and the robust shank reduces set-up time and ensures repeatable results from one operation to the next, supporting a smoother workflow on the shop floor.

Hard-wearing construction for demanding production environments

Manufactured in HSS, the cutter delivers a high degree of wear resistance and thermal stability during intermittent drilling tasks. The overall length of 61 mm keeps the tool compact, aiding access in confined setups while the specified cutting depth of 25 mm defines a clear working envelope for safe, controlled use. These characteristics make the annular cutter a practical choice where reliability and minimal rework are priorities, helping to protect downstream processes from delays caused by poor hole quality.

Practical support for workshop integration and procurement decisions

As part of a considered tooling strategy, the core drill pairs technical reliability with easy inventory management: a single-piece packaging unit simplifies ordering and stock control. Metav’s established distribution and expertise support selection, ensuring the cutter can be matched to magnetic drills and holders commonly used across industry. The proven construction and consistent specifications provide a sound basis for purchasing decisions in production, maintenance and contract workshops.
