This 3.9 mm solid carbide drill is designed for machinists and fabricators who regularly need to produce accurate holes at greater depths. The 5xD length gives extra reach while the rigid construction helps maintain straightness and finish quality in tougher materials.

• Extended service life: Solid carbide maintains edge sharpness through many cycles, so you spend less time stopping to change tools.
• Effective heat and wear protection: The TiXCo4 coating reduces friction and shields the cutting edges from high temperatures, supporting steady performance even during continuous runs.
• Stable deep-hole drilling: The 5xD ratio provides the reach needed for deeper holes without sacrificing the rigidity required for accurate, repeatable results.

Using this drill lets you complete deeper precision holes in fewer passes while keeping hole quality consistent, which reduces both cycle time and the chance of scrapped parts on production or repair work.
