The SECO 03046243 is a solid carbide jobber-length drill bit designed for high-performance drilling in ferrous and hard materials. Part of the SD205A series, it features a 140-degree point angle and a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life in demanding applications. The 12.10 mm diameter bit runs in a right-hand cutting direction with a regular spiral flute and a straight-cylindrical shank. Machinists and tool-room technicians use this drill in CNC machining centers, drill presses, and manual mills where consistent hole quality in tough materials is required.
This drill is suited for production and maintenance machining in steel, stainless steel, cast iron, and other hard materials classified under ISO material codes P, M, K, and H. The 6xD flute-to-diameter ratio provides adequate chip clearance for moderate-depth holes. Typical applications include general-purpose hole making in fabrication shops, job shops, and industrial maintenance environments. The straight-cylindrical shank seats directly in standard drill chucks or collet holders without adapters.
Designed as an OEM-style replacement or direct-use drill bit for CNC machining centers and manual drill presses accepting straight-cylindrical shank tooling in the 14.00 mm shank diameter range. Suitable for ISO material groups P (steel), M (stainless steel), K (cast iron), and H (hard materials).
Installation and tool changes must be performed with the machine powered off and spindle fully stopped. Seat the straight-cylindrical shank fully into the chuck or collet holder and verify runout before cutting. Use appropriate cutting fluid or coolant per shop practice; note this drill does not have through-coolant capability. Follow machine manufacturer torque specifications for chuck or collet nut tightening.
