The OSG Flat Bottom Carbide Drill with Through Coolant is built for precise flat-bottom holes in steel and alloys, delivering reliable performance for demanding drilling tasks. The 4.50 mm diameter and 3xD length ratio provide deep, consistent holes with accurate depth control.

• Diameter: 4.50 mm
• Drill Type: Flat bottom carbide drill
• Length-to-Diameter Ratio: 3xD
• Coolant System: Through coolant for effective chip evacuation and cooling
• Coating: EGIAS coating for enhanced wear resistance
• Material: Solid carbide construction
• Applications: Suitable for drilling in steel and alloys with high precision

Through-coolant design improves chip evacuation and cooling, reducing heat during cutting and helping extend tool life. The EGIAS coating supports high-speed performance and wear resistance, enabling durability in challenging applications while maintaining sharp, precise cutting edges for clean, flat-bottom holes.
