NOVA 25 core drill – HSS annular cutter with Weldon shank and 25 mm cutting depth

NOVA 25 is a compact annular cutter designed for precise holemaking in industrial and workshop environments; its Weldon shank ensures reliable clamping in standard holders

• Solid HSS construction
• Weldon shank 19.05 mm (3/4")
• 25 mm cutting depth
• Six cutting edges for efficient cutting

Faster holemaking with long-lasting HSS performance

The high-speed steel (HSS) body provides a reliable balance between toughness and wear resistance, which supports extended tool life under normal workshop conditions. The annular design with six cutting edges concentrates cutting forces on the periphery, enabling efficient chip evacuation and reduced centre-material removal compared with solid twist drills. This results in reduced drilling time for each bore and consistent hole quality. Proper lubrication or coolant will further prolong the life of the tool and help maintain the sharpness of the cutting lips.

Secure clamping and straightforward changeovers

The Weldon shank configuration (19.05 mm / 3/4") offers a positive, slip-resistant interface for standard Weldon holders and compatible chucks. This shank form reduces torsional movement when cutting, which improves concentricity and repeatability of holes during series work. The compact overall length of 61 mm and robust shank design also simplify tool changes and machine setup, helping to reduce downtime in small-batch or continuous production runs while maintaining consistent performance.

Practical application and service considerations

With a 22 mm diameter and 25 mm cutting depth, the cutter is optimised for making clear, burr-reduced through-holes where annular cutters are appropriate. The geometry of the cutting lips and segmented cutting edges facilitates fast removal of the material ring, producing cleaner holes with minimal rework. Routine inspection of the cutting edges and adherence to recommended feed rates will ensure predictable wear behaviour and maximise the cutter’s operational lifetime. For precision requirements, use with correctly aligned holders to preserve hole accuracy.

FAQ

What is the cutting depth of the NOVA 25?
The NOVA 25 core drill has a cutting depth of 25 mm, allowing for clean through-holes where that depth is sufficient.

What shank type does this annular cutter use?
This annular cutter features a Weldon shank 19.05 mm (3/4") for secure clamping in compatible holders.

How many cutting edges does the tool have and what is the benefit?
The tool has six cutting edges, which promote efficient material removal and smoother hole finishes compared with single-point drilling.

What material is the cutter made from?
