Strengthening precision capabilities in tungsten carbide inserts for surgical
instruments
[Chesterfield, 8 January 2026] – Kaleidex Group, a rapidly expanding contract manufacturing
organisation serving the global medical device sector, today announces the acquisition of Serrations,
a specialist manufacturer of tungsten carbide inserts for surgical instruments. The acquisition further
strengthens Kaleidex’s precision engineering capabilities and expands its offering across the surgical
instrument manufacturing and repair supply chain.
Serrations is a highly specialised manufacturer of tungsten carbide inserts, with a particular focus on
inserts for needle holders. These components play a critical role in surgical instruments, providing
the grip, sharpness, and durability required for reliable performance in operating theatres worldwide.
The business has developed proprietary expertise that delivers consistently high-quality inserts with
exceptional precision and longevity.
The acquisition enhances Kaleidex’s position as a one-stop partner for surgical instrument
manufacture and repair. By integrating Serrations’ specialist insert capability with Kaleidex’s existing
businesses, the group can offer customers an expanded, end-to-end solution encompassing both
finished instruments and critical consumable components. The business is also well positioned to
support the growing adoption of robotic surgical instruments, an area where Serrations already
supplies customers.
James Hartley, Managing Director of Serrations, said:
“Serrations has always focused on doing one thing exceptionally well: producing high-quality tungsten
carbide inserts that customers can rely on. Joining Kaleidex allows us to build on that foundation,
while benefiting from the Group’s wider infrastructure, commercial reach, and shared commitment to
precision and quality. It’s a very exciting time for the company.”
Jon Lynch, CFO of Kaleidex, commented:
“Serrations is a highly complementary addition to the Kaleidex Group. Its specialist capability and
reputation for quality align strongly with our strategy of building a connected group of medical
manufacturing businesses. This acquisition strengthens our surgical instrument offering and creates
clear opportunities for growth across our customer base.”
Gavin Meadows, the recently appointed CEO of Kaleidex added:
“This is a fantastic start to 2026 and just the beginning. With investments in new technology and
infrastructure to be announced soon, Serrations has joined at an exciting time for Kaleidex and for
contract medical manufacturing globally.”
Serrations will continue to operate from its Chesterfield facility, with its existing team retained. The
business will be integrated into Kaleidex’s cluster of specialist manufacturing companies, enabling
collaboration, shared best practice, and operational synergies over time.
