These extra-long twist drills are crafted from premium ultra-hard solid carbide with a 45-degree helix angle, available in fine-tuned diameters from 1.0mm to 3.5mm and 60mm/80mm flute lengths. They are ideal for precision drilling operations on CNC machines and high-accuracy drilling equipment.
The optimized 45° helix design guarantees smooth chip evacuation and steady cutting performance. Precision-ground sharp edges produce clean burr-free holes, while the solid carbide structure delivers excellent vibration damping and exceptional wear resistance.
Purpose-built for deep-hole and small precision hole machining of metal workpieces, they enable single-pass extended-reach drilling. They prolong tool service life, reduce replacement frequency and effectively enhance overall machining efficiency.
