The OSG Flat Bottom Carbide Drill with Through-Coolant and EGIAS coating is engineered for precise flat-bottom holes in steel and alloys, delivering reliable performance for professional machining tasks.

• Size: 8.70 mm diameter
• Through-Coolant: designed to deliver coolant directly through the drill for efficient chip evacuation and cooling
• Length-to-Diameter: 3xD length provides deeper drilling capability in a single operation
• Coating: EGIAS coated carbide for enhanced wear resistance and durability
• Geometry: flat-bottom design yields clean, accurate bottom holes
• Material suitability: optimized for steel and alloy workpieces

This combination reduces heat buildup and extends tool life while enabling high-speed performance. The through-coolant feature improves chip clearance and reliability in demanding drilling tasks, helping you achieve accurate, repeatable results in challenging materials.
