NOVA 25 annular cutter — 12 mm HSS, 25 mm cutting depth, Weldon shank

NOVA 25 is an annular cutter designed for precision hole-making in metalworking applications, offering a compact overall length and secure Weldon shank fitment

• HSS material for extended tool life
• 25 mm cutting depth for through-holes in medium plates
• Weldon shank 19.05 mm (3/4") for secure clamping
• Four cutting edges for smooth, efficient cutting

High-performance hole-making with proven tool steel

The annular cutter is manufactured from HSS, which combines hardness and toughness to withstand the stresses of repeated cutting. With four cutting edges, the tool removes material efficiently, producing a clean bore while requiring less axial force than equivalent twist drills. The 25 mm cutting depth allows clean, shallow-to-medium holes in metal plates, making the cutter suitable for routine workshop and industrial tasks. This configuration reduces cycle times and supports consistent hole quality across multiple workpieces.

Secure fit and quick tool changes for productive setups

A Weldon shank (19.05 mm / 3/4") provides a robust, anti-rotation interface with compatible holders and chucks. The short overall length contributes to rigidity, lowering the risk of run-out and improving concentricity during drilling. These design choices translate into fewer reworks and faster set-ups on common drilling rigs and portable machines where a Weldon clamping system is used. The cutter’s design supports repeatable fits, which helps maintain output continuity in batch production.

Durable geometry that keeps shops running

The cutter’s HSS material and ground cutting geometry are engineered for high durability, offering prolonged service life in general-purpose metalworking. Four precisely formed cutting lips reduce vibration and distribute forces evenly, which benefits finish quality and tool longevity. For workshops seeking dependable consumables that balance performance and durability, the tool delivers predictable results across standard mild and medium-alloy steels.

Practical dimensions for everyday workshop use

With a 12 mm diameter, 61 mm overall length and a 25 mm effective cutting depth, the tool is compact yet capable for many shop applications. The Weldon shank specification ensures compatibility with common holders, while the single-piece delivery (packaging unit 1) simplifies inventory and replacement. The cutter’s straightforward specification makes it a pragmatic choice for engineers and technicians who need a reliable annular cutter for recurring hole-making tasks in metal fabrication and maintenance operations.

FAQ

What materials is the cutter suitable for?
The NOVA 25 annular cutter is made from HSS and is intended for routine metalworking; it performs well in mild and medium-alloy steels and similar metals.

What is the shank size and why does it matter?
The tool has a Weldon shank of 19.05 mm (3/4"), which ensures an anti-rotation fit with compatible Weldon holders and improves clamping reliability in production setups.

How deep can the cutter cut in a single pass?
The effective cutting depth is 25 mm, allowing clean hole formation through medium-thickness plates without multiple passes.

How many cutting edges does the cutter feature and what is the benefit?
The tool has four cutting edges, which support smoother cutting, reduced vibration and better chip evacuation compared with fewer-edged designs.

Is the tool delivered ready to fit into a machine?
The cutter is supplied as a single unit (packaging unit 1) with a Weldon shaft for immediate installation into compatible holders
