The OSG Flat Bottom Carbide Drill is built for engineers and machinists who need deep, precise flat-bottom holes. This solid carbide drill, 4.00 mm in diameter, offers an extended 2xD long length and a durable EGIAS coating for high-speed, wear-resistant performance.

• Diameter: 4.00 mm
• Length: 2xD long length for deeper, stable drilling
• Geometry: Flat bottom design to produce clean, flat-bottom holes
• Material: Solid carbide for enhanced rigidity and precision
• Coating: EGIAS coating delivers wear resistance and high-speed capability
• Application: Suitable for challenging materials including steels, alloys, and hardened metals

The combination of solid carbide and the EGIAS coating ensures consistent hole quality deep inside workpieces, reducing burr formation and extending tool life. The 2xD long length provides dependable stability for deeper flats, enabling efficient drilling of challenging materials while maintaining tight tolerances and a smooth finish.
