Drilling Efficiency: Drilling is a critical operation late in the production cycle when component value is high. Investing in high-quality drilling tools helps achieve excellent results across various machining conditions and materials.
Superior Finish: Low-thrust geometries and a high axial rake angle reduce delamination and exit burrs, resulting in a superior hole finish. Ideal for drilling in composite materials and aircraft frames (wingboxes, fuselage, stabilizers, etc.).
