Core drill NOVA 50 – HSS core drill, 27 mm diameter with Weldon shank by C. & E. Fein

A Core drill NOVA 50 designed for precise 50 mm cutting depth applications, offering a 19.05 mm (3/4") Weldon shank for stable clamping in standard holders

• HSS construction for high wear resistance
• 50 mm cutting depth for consistent core holes
• Weldon shank 19.05 mm (3/4") for secure clamping
• 27 mm diameter for precise hole sizes

Consistent cutting performance that improves process reliability

Manufactured from HSS, this core drill delivers a balance of toughness and wear resistance that supports steady machining cycles. The design focuses on delivering repeatable hole quality at a specified 50 mm cutting depth, reducing rework and inspection time. With a 27 mm bore dimension and a precision-ground geometry, the tool promotes accurate hole tolerances across batches. The result is a measurable improvement in production dependability and fewer interruptions during runs, which supports tighter scheduling and predictable throughput.

Stable mounting and reduced runout for cleaner cores

The Weldon shank profile with a diameter of 19.05 mm (3/4") provides a positive, torque-resistant connection to holders and adaptors. This secure clamping reduces axial play and runout, which in turn lowers the risk of chatter and uneven wear on the cutting edges. For workshops that demand reliable centring and consistent core extraction, the combination of shank design and robust mounting contributes to cleaner cores and extended service intervals for downstream processes.

Designed for longevity and uninterrupted workshop use

Built with a focus on high stand time, the cutter geometry and material choice are optimised to withstand cyclic loads typical in metalworking. The tool’s overall length of 86 mm keeps the assembly compact while providing the required engagement for through and blind hole operations within the 50 mm cutting depth. Choosing a tool that maintains edge integrity over longer runs reduces changeovers and supports higher machine utilisation, delivering clear operational advantages in busy production settings.

Practical handling and integration into existing toolsets

The core drill is supplied in a single unit and fits common Weldon holders, easing integration into existing tooling systems without additional adapters. Its metric dimensions make documentation and tooling planning straightforward within a standardised workshop environment. For safe handling and best results, ensure secure clamping in a suitable Weldon holder and verify concentricity before starting the operation; regular inspection of the cutting lips will indicate when reconditioning or replacement is required to preserve hole quality.
