Whether you need Metric threaded holes or holes conform another standard, our team taps the thread according to our customers standards. We cut the thread with enough lube to ensure accurate and smooth machining. deburring and cleaning happens after fabrication. In addition, we mount helicoils in aluminum parts to ensure a strong threaded hole. The smallest thread we cut is Metric 1. Besides tapping, we also cut thread on our CNC turning machines.



Davantech’s reaming and services are essential for producing accurate and precise holes in your parts. for each hole tolerance there is a specific reamer. In addition, we use adjustable reamers. Therefore, our team of experts uses high-performance reamers to ensure that every hole we produce meets your specifications. Reaming happens at low rotation speed on CNC milling machines, turning machines and vertical drilling machines. We can work with a variety of materials, including steel, aluminum, and plastic.



Our drilling services are ideal for producing precise holes in your parts. We use advanced drilling techniques to ensure that every hole we produce is accurate and meets your requirements. We can drill a wide range of materials, including stainless steel, aluminum, and brass.

Wire Cutting

wire cutting is a way of CNC machining

Davantech’s wire cutting services are perfect for producing intricate and complex parts with tight tolerances. Our wire cutting machines use a thin wire to cut parts with extreme precision. We can wire cut a variety of materials, including stainless steel, copper, and brass.

Materials used for CNC Machining

Our custom CNC machining services can handle a wide range of metal and plastic materials. We source any materials we don’t have in stock. Nevertheless, we have the expertise to machine even the most challenging materials, ensuring that we can handle any project that comes our way.
