Our tool steel CNC machining services

Penta Precision delivers reliable, high-quality tool steel CNC machining services to customers across the UK. We machine tool steel components with precision and consistency, supporting industries where strength and wear resistance are essential. Whether you're ordering replacement tooling or custom steel tool parts, we provide solutions built to last.

We support everything from prototype tooling to full production batches. Our engineers provide advice on design for manufacture and material selection. You benefit from clear communication, expert support, and dependable results throughout your project.

We work with tool steel in both annealed and hardened states. Whether for jigs, fixtures, or wear-resistant parts, we deliver CNC-machined components that meet your technical and performance requirements.

Tool steel milling

Milling tool steel calls for robust setups and careful control of heat and tool wear. Our 4- and 5-axis machines are optimised for this challenge, allowing us to maintain accuracy across complex geometries. With fast-change tooling and efficient programming, we deliver excellent value at every batch size.

We routinely work from 2D drawings, 3D models, and sketches. Our CAM-driven workflow enables efficient setup and smooth machining. We also offer input on material selection and design improvements to help reduce costs and lead times.

From one-off spares to repeated tooling sets, our team ensures your parts are consistent and production-ready. You get strong, dimensionally accurate components that perform reliably in real-world use. Our CNC tool steel milling service is trusted by engineers across multiple sectors.

Tool steel turning

Turning tool steel requires rigid machines, proper feeds, and the right inserts. Our twin-spindle lathes and manual turning setups give us full control over the process. We machine steel tool parts to precise tolerances with repeatable results.

Whether for small batches or ongoing supply, we provide consistent quality and competitive pricing. Our turning tool steel service is suited to both prototype work and high-volume production.
