NOVA 50 — Annular cutter D 19 mm with Weldon shank, HSS, 50 mm cutting depth

A NOVA 50 annular cutter designed for efficient holemaking in metalworking, equipped with a Weldon shank and 50 mm cutting depth for use in magnetic drilling and portable drilling rigs.

• HSS construction for long tool life
• Weldon shank 19.05 mm (3/4") secure fitting
• 50 mm cutting depth for deeper bores
• 19 mm diameter for precise holemaking

Faster, cleaner holes with ring‑cutting technology

The annular cutter removes material as a ring rather than grinding the full core, which reduces power consumption and cycle time compared with solid twist drills. Manufactured from HSS, this tool keeps its hardness under cutting temperatures and is engineered to produce a smooth bore with minimal burr formation. The five cutting edges (5 flutes) distribute cutting forces evenly, so productivity is increased while the load on the machine is reduced. This makes the cutter particularly suited to workshop and industrial settings where repeatable, metric‑accurate holes are required.

Secure mounting and machine compatibility for reliable operation

Designed with a Weldon shank, the cutter locks in place with the standard set‑screw system used on magnetic drills and compatible holders; the shank measures 19.05 mm (3/4") for robust clamping. The overall length of 86 mm gives a compact tool profile while still providing the required reach for the specified cutting depth. The Weldon interface simplifies tool changes and prevents rotation in high‑torque situations, ensuring the cutting edges remain accurately positioned throughout the job.

Durable construction and straightforward workshop use

Built for high service life, the cutter benefits from proven geometry and precise metric dimensions that suit series production as well as one‑off tasks. HSS material provides a balanced combination of toughness and wear resistance for common metalworking tasks, and the tool is programmed to meet standard metric hole sizes without additional setup. For those less familiar with annular cutters: the slug that is freed during cutting can be ejected easily from the arbor, reducing cleanup time and leaving a finished bore that typically requires little secondary work.

FAQ

What machines is this annular cutter compatible with?
The NOVA 50 annular cutter is intended for use with magnetic drilling machines and portable drilling rigs that accept a Weldon shank; the Weldon shank 19.05 mm (3/4") secures the tool in standard Weldon holders.

Can this cutter achieve a full 50 mm cutting depth in one pass?
Yes, the tool is specified with a 50 mm cutting depth, which represents the effective penetration the cutter is designed to achieve under normal machining conditions.

How does the cutter compare to a twist drill for a 19 mm hole?
An annular cutter removes only the material of the bore wall, so the NOVA 50 typically produces faster drilling times, less power draw and a cleaner finish than a solid twist drill of comparable diameter.

Is the NOVA 50 suitable for series production in a workshop environment?
The HSS construction and five‑flute geometry deliver high service life and repeatable results, making the cutter well suited to both single‑part and small‑batch production tasks.

What maintenance is recommended to extend tool life?
Regular cleaning of chips and inspection of the cutting edges after use is advised; regrinding should be performed by a qualified service when wear affects hole quality.
