The OSG Flat Bottom Carbide Drill with Through-Coolant delivers precise flat-bottom holes in steel and alloy workpieces, built for reliability in demanding drilling tasks.

• Diameter: 10.30 mm
• Drilling depth: 3xD length ratio for deeper, consistent holes
• Through-Coolant: Through-coolant design for improved chip evacuation and effective cooling
• Coating: EGIAS coating enhances wear resistance for high-speed performance
• Material: Solid carbide construction for rigidity and durability
• Geometry: Flat-bottom drill tip for clean bottoms and precise hole profiles
• Applications: Suitable for steel and alloy drilling in demanding applications

The through-coolant flow keeps chips moving away and temperatures down, extending tool life and reducing finish defects. With a 3xD depth capability, you can reach deeper holes in a single pass, improving cycle times. The EGIAS coating reduces wear, helps maintain edge sharpness, and supports higher cutting speeds. The flat-bottom geometry yields true, square holes ideal for seating dowels, bushings, or fasteners, delivering consistent accuracy and reliability in tough environments.
