ø18.00 mm 3D Solid Carbide
Coolant-Thru Drill
The 3D depth ratio is the workhorse of through-hole and short-blind-hole drilling. With the shortest flute-to-diameter ratio in the range, the 3D offers maximum rigidity and excellent straightness in steels, cast iron, and aluminium alloys. Ideal for high-feed automotive and general engineering applications where cycle time is critical.
