Vertex VRA-NT30 Right-angle Head (90°) — 160 mm, max. 2000 r.p.m.

A robust VRA-NT30 right-angle head designed for NT toolholder installations, providing precise angular machining where straight spindle access is restricted.

• 90° right-angle configuration
• 160 mm external diameter
• Rated up to 2000 r.p.m.
• Compatible with NT30 bores 85.725–86 mm

Increased throughput where access is limited

The right-angle head design translates rotational power into productive machining in locations where a straight spindle cannot reach. With a 160 mm external diameter and a balanced mass of 13 kg, the unit maintains stability during operation while keeping a compact footprint on the machine table. The 2000 r.p.m. maximum speed is specified to preserve bearing life and deliver consistent cutting conditions; this rating supports moderate cutting feeds while reducing vibration compared with higher-speed, lower-mass adaptors. Overall, the combination of precision and controlled rotational speed results in reproducible cycle times and fewer rejects in batch runs.

Straightforward integration into NT toolholder systems

The head is specified for a drill-head bore of 85.725–86 mm (Type NT), enabling direct seating in standard NT30 interfaces without additional shimming when tolerances are observed. The NT30 compatibility ensures a familiar mounting procedure for workshop technicians and supports mechanical repeatability when changing setups. Because the interface is a standard industrial form, existing fixtures and clamping routines can be reused, which reduces setup time and simplifies changeovers between different jobs while preserving concentricity and axial alignment.

Robust build for reliable operation

Constructed for workshop use, the assembly’s mass and geometry contribute to smooth running under rated conditions; the 13 kg weight helps damp resonance and stabilise cutting forces during right-angle operations. The specified 2000 r.p.m. limit is chosen to balance cutting capacity and component longevity, ensuring bearings and seals operate within their design envelope. Regular inspection of bearing play and fastening torque, together with adherence to the speed limit, will preserve the head’s performance and reduce unplanned downtime. These design choices favour steady, predictable production rather than pushing the envelope for extreme speed.

Suitable uses and basic maintenance guidance

This right-angle head is particularly suited to operations requiring side-entry drilling, milling or reaming where direct spindle approach is impractical—examples include bores at an angle to the primary spindle axis and workpieces with deep or obstructed features. Before first use, verify the drill-head bore 85.725–86 mm and confirm secure clamping into the NT30 mounting. Maintenance is uncomplicated: periodic checks of mounting faces, fastener torque and bearing condition will keep the head within tolerance. Where specialised finishes or cutting data are required, pairing the head with appropriate tooling and feeds will optimise surface integrity and cycle efficiency.

FAQ

What is the maximum permissible speed for this right-angle head?
The maximum speed for the Vertex VRA-NT30 right-angle head is 2000 r.p.m., which ensures reliable bearing life and stable machining.

Which toolholder interface is required for installation?
Installation requires an NT30-compatible mounting; the head is designed for a drill-head bore of 85.725–86 mm (Type NT) to ensure proper seating.

How heavy is the unit and what does that mean for machine setup?
The assembly weighs 13 kg; this mass contributes to run-out stability but requires correct clamping and balance checks during setup to maintain concentricity.

Is the VRA-NT30 suitable for high-speed finishing operations?
The VRA-NT30 is optimised for stable, moderate-speed operations up to 2000 r.p.m. and is best used where steady cutting and repeatability are priorities rather than extreme high-speed finishing.

Are there images or technical views available to assess fitment?
Yes, image assets for visual inspection are provided (VRA-R8-main.png and VRA-R8-detail.png) to assist in evaluating mounting and clearance.
