In its 30th year Perfect Bore Manufacturing Ltd a leading UK manufacturer has seen many changes in the deep hole drilling sub-contract market over the past 3 decades. Specialising in:

• Gundrilling and BTA Deephole Boring: bore production from 1.8mm to 150mm dia up to 2.8mtrs.

• Honing: finishing bores with precise surface finishes from 1mm to 340mm diameter, max stroke at 340mm dia being 3.0 mtrs.

• CNC Turning: from first stage turning operations to finish turning operations producing specialist bores and OD features up to 900mm dia and 3 mtrs.

• CNC Grinding & Superfinishing: External grinding to sub-micron tolerances on parts 3-300mm dia and up to 1000mm in length.

Since being sold by the US Conglomerate company, Dover Corporation Inc in 2004 the business has gone from strength to strength whilst surviving 2 deep recessions. Perfect Bore has continued to expand through heavy investment into its machinery, management infrastructure and employees, leading to an increase in its manufacturing footprint from 6000 sq ft to 32,000 sq ft. This investment has enabled the company to meet the increasing demands of its customers to provide additional services, including preparatory turning operations, boring and honing of billets up to 300 mm diameter and three metres in length. Its £1 million investment into a new CNC/Prismatic Drilling division, allows it to drill multiple holes in various shaped blocks and offset holes in round billets. These machines can provide cost effective solutions to drilling holes in mould tools for high-end automotive applications, manifolds for oil and gas tool applications and plates for nuclear fabrications.

Perfect Bore successfully transitioned over to AS9100:2016 and gained ISO 14001:2015 & BS18001:2007 approvals last year. The company was accepted as a partner within the Fit for Nuclear programme during December 2015 and is today is committed to providing the aerospace, defence, power generation (including nuclear) and oil and gas markets with bore solutions for highly critical parts.


For over 30 years Fintek has been at the forefront of surface finishing.  As UK agent for OTEC Präzisionsfinish GmbH, we have access to an unrivalled range of disc, drag, stream and pulse finishing machines capable of producing surface Ra values to 0.01 μm in a fraction of the time taken by costly hand finishing and other traditional processes.

Achieving high quality metal part surface finishes is no longer a luxury – it is a vital necessity in all branches of advanced engineering. Tolerances are increasingly precise and hard, if not impossible, to achieve by hand. Customer expectations for more reliable end-products relentlessly drives development. From single units to fully automated systems for mass finishing, we can supply everything you need to ensure repeatable, cost effect and assured surface finishing quality.

We also provide a full range of deburring, fine grinding, edge radiusing, smoothing, polishing and superfinishing subcontract services using the latest generation of OTEC equipment. A same-day service is available. Whether you want a machine or to outsource your metal part finishing to us, we are happy to process a trial part, free of charge.
