NOVA 50 core drill — 30 mm HSS annular cutter with Weldon shank (FEIN)

The NOVA 50 core drill is a high-performance HSS annular cutter designed for fast, clean 30 mm bores in steel and similar materials, featuring a Weldon 19.05 mm (3/4") shank for secure toolholding and industrial drilling setups.

• HSS construction for robust cutting
• Weldon shank 19.05 mm (3/4") secure fit
• 30 mm bore diameter with 50 mm cutting depth
• Eight cutting edges for efficient chip ejection

Faster holemaking with less machine load

The solid high-speed steel geometry and annular cutting principle reduce axial thrust compared with twist drills, meaning less stress on the machine and quicker penetration. With eight cutting edges, the cutter evacuates chips more efficiently and produces cleaner hole walls, which translates into fewer secondary operations and shorter cycle times. This efficiency benefits production environments where throughput and tool longevity are measured precisely.

Dependable clamping and concentricity for consistent results

A Weldon shank 19.05 mm (3/4") ensures firm retention in chucks and arbors commonly used on magnetic drills and pillar machines, minimising slippage and runout. The tool’s 86 mm overall length provides sufficient reach for standard setups while retaining stiffness for accurate centring. Designed with metric dimensions and a controlled geometry, the cutter supports repeatable hole quality across batches, reducing scrap and rework.

Built for productivity and predictable maintenance intervals

The annular cutter’s 50 mm cutting depth gives a clear specification for process planning and tool change scheduling. High wear resistance and the tool’s construction reduce the frequency of reconditioning, helping to lower operational costs and interruptions. For fabricators, maintenance teams and toolrooms seeking consistent hole quality and predictable service life, this annular cutter offers a balance of performance and cost-effectiveness that supports steady production flows.

FAQ

Is the NOVA 50 suitable for drilling structural steel? The NOVA 50 core drill, made from HSS, is suitable for drilling steel and similar ferrous materials when used with appropriate cutting parameters and coolant.

What clamping system is required for the cutter? A Weldon holder with a 19.05 mm (3/4") collet or set-screw clamp is required to secure the cutter; the Weldon shank ensures stable clamping for the specified cutting depth.

How deep can the cutter bore in one pass? The defined cutting depth is 50 mm; this is the recommended maximum depth for a single, clean annular cut with this tool.

Which machines are commonly used with this annular cutter? Magnetic drills, pillar drills and machining centres equipped with Weldon-type holders are commonly used with this style of core drill for efficient holemaking.
