VRA-R8 90° right-angle head — Max 2,000 rpm, 138 mm body

VRA-R8 is a right-angle milling head designed for precision angled machining on milling centres and machining stations, offering a compact footprint and reliable performance for workshop and industrial applications

• 90° right-angle head for angled machining
• Max 2,000 rpm operational speed
• 138 mm body diameter for robust support
• Sturdy 12.5 kg construction for stability

Consistent performance for angled operations

The 90-degree configuration delivers reliable, repeatable results when the tool axis must be reoriented. With a rated maximum speed of 2,000 rpm, the head maintains stable rotational behaviour under typical finishing and roughing feeds. The relatively large 138 mm body diameter increases bearing spacing, reducing deflection and helping to preserve tool geometry during side loads. That translates into fewer reworks and better dimensional adherence on angled faces.

Heavy-duty build that minimises vibration

A mass of 12.5 kg and a compact, rigid housing combine to dampen vibration and improve surface finish during aggressive cuts. The robust construction supports consistent concentricity and reduces chattering, which in turn extends cutting-edge life and lowers tooling costs over time. The design concentrates mass close to the mount, keeping inertia where it benefits machining stability without compromising accessibility at the workpiece.

Integration and compatibility with Type R drill heads

The head is compatible with a Type R drill head diameter range of 85.725–86 mm, enabling straightforward integration with existing spindle interfaces of the same family. The connection geometry and maximum speed rating should be checked against the host machine’s spindle specification; where matched, the attachment functions as an efficient means to add angled machining capability without major machine modifications. Clear geometric compatibility shortens retrofit time and reduces setup complexity.

Logistics, supply certainty and workshop benefits

Availability is supported by fast dispatch from stock, reducing downtime compared with long-lead custom units. For shops seeking to add angled operations without complicating production flow, this right-angle head provides a pragmatic balance between performance and ease of supply. Combined with routine maintenance, the unit supports predictable throughput and helps maintain delivery reliability in production schedules.

FAQ

What spindle speed is recommended for this right-angle head?
The VRA-R8 is rated to a maximum of 2,000 rpm; adherence to this limit ensures bearing life and consistent performance under normal cutting conditions.

Is the VRA-R8 suitable for heavy side-loading operations?
The 12.5 kg mass and 138 mm body diameter give the unit improved damping and reduced deflection, making it suitable for moderate side loads typical of angled milling and finishing.

Which drill head sizes are compatible with the attachment?
Compatibility is provided for Type R drill heads with a diameter of 85.725–86 mm, permitting direct integration where the host machine accepts that interface.

How does the head contribute to tool life and surface quality?
Stable bearing spacing and rigid housing minimise vibration and runout, which helps to extend cutting tool life and produce a more consistent surface finish on angled faces.

Can this head be used across different machining centres?
Where the spindle or mounting interface matches the Type R dimension range and the machine can operate within the head’s maximum speed, the VRA-R8 is suitable for retrofit on compatible milling centres.
