5xD Standard Carbide Drills

The main advantage is the balance between drilling reach and tool rigidity. It can produce deeper holes than a 3xD drill without requiring the longer structure and more demanding operating conditions of an 8xD or deep-hole drill.

Landun 5xD carbide drills can be selected for steel, stainless steel, cast iron, aluminum alloys, titanium alloys, and other engineering materials according to the specific drill geometry, coating, and coolant configuration.

Internal coolant is recommended for demanding 5xD applications because it helps deliver coolant closer to the cutting edges and supports chip evacuation. However, some diameters, materials, and drilling conditions may also use external coolant. The final selection should be based on the drill model and machining conditions.

Yes. Landun can review non-standard diameters, special flute lengths, step geometries, coolant-hole requirements, special point designs, and drawing-based custom carbide drill projects.
