At TEK4, we design and manufacture advanced Fast Hole Drill (FHD) EDM machines for the accurate and efficient drilling of cooling holes in aerospace and industrial gas turbine (IGT) parts — including blades, vanes, and segments.



Our systems combine leading-edge technologies to meet the most demanding manufacturing requirements:



EDM Fast Hole Drilling for straight and shaped holes
Laser for precision drilling, cutting, and ceramic coating ablation
ECM (Electrochemical Machining) for deep STEM drilling of complex cooling passages​

With a focus on performance, reliability, and innovation, TEK4 delivers complete drilling solutions trusted by global OEMs and tier-one suppliers.

Our machines are built in Leicester in the UK.

We also have a machine showroom and spares warehouse in Greenville, South Carolina. Soon we will be able to organise machine demos in Greenville.
