The OSG Flat Bottom Carbide Drill with Through Coolant is designed for precision flat-bottom holes in steel and alloys, delivering reliable performance at higher speeds. Its 3xD length and through-coolant design optimize depth, cooling, and chip evacuation for demanding drilling tasks.

• Diameter: 4.40 mm
• Material: Carbide for rigidity and wear resistance
• Coating: EGIAS coating for enhanced wear resistance and durability
• Length-to-diameter ratio: 3xD
• Through-Coolant: Yes, for optimized cooling and chip evacuation
• Geometry: Flat-bottom design for true flat-bottom holes
• Applications: Ideal for drilling into steel and alloys

This drill reduces heat buildup and wear while maintaining hole accuracy, thanks to its through-coolant design and durable coating. The 4.40 mm diameter provides precise sizing, and the 3xD length supports deeper hole reaches without sacrificing rigidity. The flat-bottom geometry yields clean, level bottoms suitable for high-precision components, making it a reliable choice for machinists tackling demanding steel and alloy projects.
