Meet the OSG Flat Bottom Carbide Drill—a precision tool built for clean, flat-bottom pockets in demanding metalworking tasks. With a 0.91 mm diameter, solid carbide core, 2xD length, and an advanced EGIAS coating, it’s designed for high-speed drilling and long tool life.

• Diameter: 0.91 mm
• Length: 2xD solid carbide design for stiffness and stability during drilling
• Material: Solid carbide for rigidity and accurate hole positioning
• Coating: EGIAS coating to boost wear resistance and extend tool life at high speeds
• Geometry: Flat-bottom geometry to produce precise flat-bottom holes with minimal burr
• Applications: Effective in steels, alloys, and hardened materials requiring high-quality hole finishes

Designed for machinists who demand repeatable, burr-free precision, this drill delivers clean end faces, excellent hole quality, and reliable performance in challenging materials. Its combination of a tiny diameter, robust solid carbide core, and durable coating makes it suited for micro-drilling, fine-feature pockets, and applications where hole concentricity and surface finish matter.
