The OSG Flat Bottom Carbide Drill with Through Coolant is designed for precision flat-bottom holes in steel and alloys. At 4.90 mm in diameter with a 3xD length and an advanced EGIAS coating, it combines depth, durability, and through-coolant efficiency for demanding machining tasks.

• Diameter: 4.90 mm
• Drill type: Flat bottom carbide drill
• Through coolant: Through-coolant design for efficient chip evacuation and cooling
• Coating: EGIAS coating for enhanced wear resistance and high-speed performance
• Length-to-diameter ratio: 3xD length for increased drilling depth
• Material: Carbide construction for rigidity and long tool life
• Recommended use: Suitable for drilling steel and alloys in high-precision tasks

This drill delivers clean, flat-bottom holes with consistent depth, thanks to its flat-tip geometry. The through-coolant design ensures efficient chip evacuation and effective cooling, minimizing heat buildup. The EGIAS coating enhances wear resistance for longer tool life during high-speed drilling in challenging materials. The 3xD length supports deeper holes in a single pass, making it a reliable choice for precision-focused machining projects.
