What Mollart Engineering does

Mollart Engineering is a UK-headquartered precision mechanical engineering business that has operated continuously since 1929. The company is privately held following a March 2016 management buy-out by five existing directors, and it runs two limited companies: Mollart Engineering (Chessington) Limited and Mollart Engineering (Resolven) Limited. Operations are split between a 30,000+ sq ft headquarters facility in Chessington, Surrey and a second 30,000+ sq ft manufacturing site in Resolven, South Wales. The company's core technology centres on deep hole drilling, including gun drilling, BTA drilling, ejector drilling, roller burnishing, and 5-axis CNC machining, with hole diameters from \u00d80.5mm to \u00d8200mm and depths up to 3000mm, supported by 12 deep hole drilling spindles, multiple Mazak Integrex 5-axis machines, Wenzel CMMs, an ISO 6 (Class 1,000) cleanroom, and 20,000 psi pressure testing capability.

The company operates a dual revenue model. The first stream is subcontract precision machining services, sold through B2B direct sales and website enquiry forms to enterprise customers in aerospace, oil and gas, defence, medical, nuclear, semiconductor, telecommunications, and automotive, with work performed under AS9100:D and ISO9001:2015 certifications. The second stream is cutting tool sales, anchored by an exclusive UK agency for botek Germany gundrills and BTA tooling, supplemented by ECOROLL roller burnishing tools, Bencere back chamfering and IRU grooving systems, Autofacer spot-facing tools, E-Z Burr deburring tools, Ohio Tool Works honing stones, and regrinding / re-tipping services. Pricing is quote-based and not publicly disclosed, with revenue generated per project based on component complexity, material specification (including Inconel, titanium, and superalloys above 150ksi), tolerance requirements, and volume. The customer base is described in terms of blue-chip and world-leader enterprises across the eight served verticals, with no individual customer publicly named.

Broad incumbents

• Walter Tools (Walter AG / Sandvik): German precision tooling manufacturer (now part of Sandvik) with a strong metal cutting and drilling product range. Adjacent competitor to Mollart's botek-distributed tooling portfolio, especially in drilling inserts and precision cutting tools.
• Sandvik (Coromant and Machining Solutions): Swedish global leader in metal cutting tooling and machining solutions, with a deep hole drilling product range. Competes with Mollart's tooling offering but as part of a much broader portfolio rather than as a deep hole drilling specialist.
• Kennametal: US-listed tooling and wear-resistant solutions provider serving aerospace, defence, and industrial markets. Broadly comparable customer base and tooling/machining overlap, though Kennametal operates at vastly greater scale and scope than Mollart.

Direct peers

• Senior plc: UK-listed precision engineering group serving aerospace, defence, and industrial markets with complex fabricated and machined components. Highly comparable business model, customer base overlap (aerospace, defence), and UK manufacturing footprint.
• Dawson Shanahan: UK precision machined components manufacturer serving aerospace, medical, automotive, and industrial customers. Comparable in scale, customer mix, and subcontract precision machining profile, with overlapping precision deep hole and turned-component capabilities.
• Guhring: Major German cutting tool manufacturer with a substantial deep hole drilling product line (including gundrills and BTA tooling) and a global service footprint. Directly comparable to Mollart on tooling products and on subcontract precision machining in deep hole drilling.
• TBT Tiefbohrtechnik: German specialist in deep hole drilling machines, tooling, and contract deep hole drilling services. Closest pure-play peer to Mollart's deep hole drilling service offering and the underlying gundrill/BTA tooling technology base.
• Hayward Tyler: UK precision engineering specialist supplying pumps, motors, and high-spec components for power generation, defence, and nuclear markets. Overlaps with Mollart in precision components for nuclear and energy applications requiring deep hole drilling and exotic alloy work.
• Botek Präzisions-Bohrwerkzeuge GmbH: German world-leading manufacturer of gundrills and BTA tooling. Botek is both Mollart's exclusive UK partner and a direct competitive force in deep hole drilling tooling globally — making it the closest comparable for both Mollart's tooling distribution and subcontract service lines.

Regional players

• Wallwork Group: UK heat treatment and subcontract finishing services group serving aerospace, defence, and motorsport. Comparable UK subcontract industrial services footprint and customer overlap, though focused on heat treatment rather than deep hole drilling.
