Seco 02450039 Carbide Jobber Drill 6.90mm Tialn SD205A

Product Description

The SECO 02450039 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. It features a 6.90 mm (0.2719 inch) diameter, a 140-degree split-point geometry, and a TiAlN (titanium aluminum nitride) coating that extends tool life in high-temperature cutting environments. Overall length is 3.5854 inches, with a 2.0882-inch flute length and a straight-cylindrical shank measuring 0.3152 inches in diameter. The right-hand spiral flute configuration with a 7xD flute-to-diameter ratio supports efficient chip evacuation. This drill is suited for use in CNC machining centers and drill presses operated by machinists and tooling professionals.

The 02450039 is rated for drilling into a wide range of workpiece materials, including steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials. The 140-degree point angle and regular spiral type make it effective in applications where accurate entry and controlled chip flow are required. The SD205A series targets production drilling scenarios where consistent hole tolerances and extended run times are priorities. Drill bit diameter tolerance is m7, supporting close-tolerance hole requirements in precision machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating provides thermal protection and reduced friction in high-speed applications
• 140-degree point angle for accurate self-centering on entry and reduced thrust force
• Right-hand, two-flute spiral design with 7xD ratio for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• ANSI-standard specification for consistent dimensional compliance

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for CNC machining centers, drill presses, and multi-spindle setups handling steel, stainless steel, non-ferrous metals, superalloys, titanium, and hard materials within the 6.00 mm to 7.00 mm (0.2500 to 0.3000 inch) diameter range.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists familiar with cutting tool setup and machine operation. Ensure the spindle is fully stopped and the machine is locked out before inserting or removing the tool from the chuck or collet. Verify that shank diameter and chuck capacity are compatible before seating the tool. Follow machine manufacturer feed and speed recommendations for the target workpiece material and do not exceed the maximum drilling depth of 2.0882 inches for this bit.
