NOVA 50 core drill D.33 mm (Weldon) — HSS, 50 mm cutting depth by C. & E. Fein GmbH

The NOVA 50 core drill is a high-performance HSS core cutter for precise 33 mm holes in metal, fitted with a 19.05 mm (3/4") Weldon shank and a 50 mm effective cutting depth.

• HSS construction for long life
• Weldon shank 19.05 mm (3/4")
• 50 mm cutting depth for standard cores
• Metric dimensions, high service life

Consistent, accurate 33 mm holemaking for production use

Designed for workshop and industrial environments, this HSS core drill delivers reliable performance on standard metalworking tasks. The solid high-speed steel construction provides a balance of hardness and toughness, which means stable cutting performance and longer service intervals. With a 33 mm diameter and 50 mm cutting depth, the tool is suitable for through- and partial-hole applications where a clean core and predictable chip evacuation are required. The geometry with eight cutting edges ensures efficient material removal while preserving hole tolerance, so less rework is needed and cycle times remain predictable.

Secure clamping and fast tool changes with Weldon shank

The Weldon shank (19.05 mm / 3/4") gives positive axial and torsional fixation in tool holders and chucks commonly used in industrial drilling setups. This reduces slippage under high torque and simplifies tool changes when paired with standard Weldon holders. The compact overall length of 86 mm makes the cutter suitable for confined set-ups where overhang must be limited. For procurement and workshop planning, the tool is delivered as a single unit, optimising inventory control and reducing unnecessary surplus.

Practical benefits: longer uptime and easier handling

Fewer interruptions in production are achieved through the drill’s robust design and high service life, which lowers the frequency of replacements. For operators less familiar with technical terminology: the Weldon shank provides a firm mechanical grip, while the HSS material combines heat resistance and edge retention so the cutter keeps cutting accurately for longer. These attributes translate into a measurable reduction in downtime and consistent hole quality across batches, supporting predictable throughput and cost-efficiency in small to medium-sized production runs.
