Seco 03046284 Jobber Drill 16mm Solid Carbide Tialn 140 Deg

Product Description

The SECO 03046284 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding materials. Built to the SD205A series, it features a 16.00 mm diameter, a 140-degree split point angle, and a TiAlN coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank measures 16.00 mm in diameter and 48.00 mm in length, with an overall length of 133.00 mm (5.24 inches). Right-hand spiral flutes clear chips efficiently, making this drill well-suited for production and maintenance machining environments where precision and tool longevity matter.

This drill bit is intended for use on steel, stainless steel, cast iron, and other hard materials, corresponding to ISO workpiece material codes P, M, K, and H. The 5xD flute-to-diameter ratio and 83.00 mm flute length support a maximum drilling depth of 63.00 mm (3.27 inches). It is appropriate for CNC machining centers, drill presses, and manual machine tools where a straight-cylindrical shank is compatible. No coolant-through capability is present, so external or flood coolant application is typical for extended production runs in harder workpiece materials.

Key Features

• 16.00 mm diameter with straight-cylindrical shank for standard toolholder compatibility
• 140-degree point angle reduces thrust force and improves self-centering on entry
• TiAlN coating provides oxidation resistance and extended tool life in ferrous materials
• Solid carbide construction delivers rigidity and wear resistance over high-speed steel alternatives
• Two right-hand spiral flutes with regular spiral type for consistent chip evacuation
• Conforms to ANSI standards; fits the SD205A drill series

Compatibility

Designed as a direct-fit replacement within the SECO SD205A series. Compatible with machine tool spindles and drill chucks accepting a 16.00 mm straight-cylindrical shank. Suited for steel, stainless steel, cast iron, and hard material workpieces per ISO material codes P, M, K, and H.

Installation Notes

Installation is performed by machinists or tool-and-die technicians on CNC or manual machine tools. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank firmly in the collet or drill chuck to the tool manufacturer recommended clamping torque for the holder type in use. Inspect the cutting edges and coating condition before each use; carbide tooling is brittle and should not be dropped or contacted with hard surfaces during handling.
