NOVA 50 annular cutter — HSS, Weldon shank, 18 mm diameter

The NOVA 50 annular cutter is a compact core-drilling tool intended for industrial holemaking tasks, offering a 50 mm cutting depth and a Weldon shank for secure clamping in standard holders

• HSS construction for durability
• Weldon shank 19.05 mm (3/4")
• 50 mm effective cutting depth
• Five cutting edges for fast cutting

Faster holemaking with consistent bore quality

This annular cutter delivers efficient metal-removal through its five cutting edges, which reduce cutting forces and spread wear more evenly than single-point drills. Manufactured from HSS, the tool is designed to maintain cutting geometry under load, extending service intervals and supporting uninterrupted production. The 18 mm diameter combined with the 50 mm cutting depth enables single-pass core drilling where applicable, reducing cycle times and improving part repeatability. The result is a measurable productivity gain when replacing worn or underperforming cutters with a high-quality HSS option.

Secure mounting and simplified tool changes

The Weldon shank 19.05 mm (3/4") provides a robust connection to compatible holders and magnetic drill chucks, improving torque transmission and minimising slippage during demanding operations. The 86 mm overall length keeps reach compact while maintaining sufficient shank engagement for safe clamping. For workshops integrating new tooling, Metav Werkzeuge can assist with compatibility checks and holder recommendations to ensure optimal clamping and tool life. This approach reduces unexpected downtime and helps maintain a predictable production flow.

Practical guidance for reliable results

The cutter’s metric dimensions and standard Weldon shaft simplify inventory and replacement planning across industrial environments. The annular design removes a solid core, producing a clean bore with reduced power draw compared with twist drills of similar diameter; this is particularly beneficial where efficient chip evacuation and surface finish matter. Regular inspection of the cutting lips and timely resharpening or replacement maintains performance and safety. The tool’s specification focuses on durability and functionality, providing a predictable service profile in routine workshop applications.
