CNC machining
We deliver high-quality CNC machined components for customers across the UK. We specialise in CNC milling and CNC turning, as well as high-precision batch production. We work with a broad range of materials including aluminium, stainless steel, engineering plastics, and more.
Batch production
We offer one-off prototyping when it is part of a confirmed pathway to medium or high volume production. Our focus is on delivering long-term manufacturing solutions where repeatability, reliable quality, and proactive communication are critical to success.
Ongoing Partnerships
We take pride in building lasting relationships with our customers by delivering consistently high standards of quality. From initial enquiry to final delivery, we aim to be a trusted partner you can rely on for responsive service and dependable results.
Our commitment to you
Quality is embedded in everything we do. We are ISO 9001:2015 certified and follow rigorous internal procedures that go beyond standard compliance requirements.

We maintain full traceability and documentation across all projects, and we foster a continuous improvement culture backed by regular staff development and training.
1998: From Humble Beginnings
Penta Precision was born when five like-minded engineers came together in a modest 1,500 square foot workshop at the Portsmouth Enterprise Centre. United by a shared vision and a passion for machining, they laid the foundations for a business built on quality, reliability, and teamwork.
2007: Early Recognition and Growth
Penta's dedication to best practices was officially recognised with the MAS South East Regional Best Practice Award.
As our reputation grew, we expanded into Aspen House, adding 2,000 square foot of much-needed room for our growing team and capabilities
2012: Aerospace-Grade Quality
Achieving ship-to-stock status with a major aerospace customer was a pivotal milestone. Our quality performance had exceeded 99.5% for two consecutive years.
This standard has been proudly maintained ever since. It validated our commitment to exceptional standards and opened doors to more advanced, high-precision projects.
2021: Under One Roof
We moved to our current home at Murrills Industrial Estate, doubling our factory footprint and reuniting the whole team under one roof. The move was not just about space.
We also invested in new capabilities, including our first 5-axis machining centre.
2025: A New Chapter
Penta Precision acquired RDSW Limited, trading as RDF Precision. This exciting partnership expands our CNC turning capability and strengthens our position in the UK precision machining market. It marks a new chapter that stays true to our founding vision.
Our journey continues, grounded in the same principle that started it all: to become the engineering company everyone wants to work for and everyone wants to buy from.
