The OSG Flat Bottom Carbide Drill with Through Coolant is engineered for precision flat-bottom drilling in steel and alloys, built for machinists who need repeatable, accurate hole geometry. Featuring a 3xD length ratio and through-coolant design, it delivers deeper reach, efficient chip evacuation, and extended tool life.

• Diameter: 6.60 mm
• Drill geometry: Flat bottom for precise bottom-face holes
• Length-to-diameter ratio: 3xD
• Through-Coolant: Through coolant for effective cooling and chip evacuation
• Coating: EGIAS coated for wear resistance and durability
• Material: Carbide
• Applications: Drilling into steel and alloys with clean, flat-bottom results

This drill delivers tight tolerances and consistent flat-bottom holes, while through-coolant enhances heat management and chip removal to reduce rework. The EGIAS coating supports high-speed cutting and longer tool life in demanding steel and alloy applications.
