At SQM, our drilling services are designed to deliver precision, repeatability, and full compliance with your technical drawings. Using CNC-controlled drilling equipment, we produce through-holes, blind holes, countersinks, and complex hole patterns with consistent depth, diameter, and positional accuracy across every batch. Each drilling operation is programmed directly from the validated 3D CAD model, eliminating manual error and ensuring alignment with the overall geometry of the part. Whether the base material is cast iron, steel, aluminum, or a high-strength alloy, we use application-specific drill bits and tool coatings to maintain surface integrity, prevent burrs, and extend tool life. Tolerances are verified using in-process measurement and post-machining inspection via CMM or gauges, depending on customer requirements. For multi-stage components, drilling is often integrated with milling or tapping operations in a single setup, reducing handling and improving efficiency.
We support both low-volume prototyping and high-volume production, with full documentation available for quality traceability. SQM's drilling capabilities are widely used in parts for the automotive, energy, construction, and rail sectors, where each hole must serve its mechanical or fluidic function without deviation.
