The OSG Flat Bottom Carbide Drill with Through Coolant is a precision drilling tool designed for flat-bottom holes in steel and alloys. With a 3xD length and through-coolant design, it delivers depth, cooling, and reliability for demanding machining tasks.

• Diameter: 3.80 mm
• Geometry: Flat bottom to produce true-flat bottoms with clean walls
• Through-Coolant: Integrated coolant channel for effective chip evacuation and cooling
• Length to Diameter: 3xD for increased drilling depth while maintaining rigidity
• Coating: EGIAS coating for enhanced wear resistance and high-speed performance
• Material: Solid carbide for durability and rigidity in steel and alloys

Achieve precise, repeatable flat-bottom holes with improved surface finish and seating accuracy. The through-coolant design minimizes heat buildup and ensures efficient chip removal, extending tool life even under demanding feeds and speeds. The EGIAS coating supports sustained performance at high cutting speeds, making this drill a reliable choice for professional machinists working with steel and alloy materials.
