5xD Micro Carbide Drills for Medium-Depth Precision Holes
The 5xD micro carbide drill series is designed for precision small-diameter holes requiring greater reach than a 3xD micro drill. Its extended flute supports depths of up to five times the drill diameter while balancing rigidity, chip evacuation, hole positioning, and straightness. Because the longer cutting section is more sensitive to runout, unstable entry, vibration, heat, and chip congestion, stable machining conditions are essential. Landun 5xD micro drills are available with material-specific geometries and coatings for steel, stainless steel, cast iron, aluminum, titanium, and other precision engineering materials.
