Seco 03046273 Solid Carbide Jobber Drill 14.90mm Tialn

Product Description

The SECO 03046273 is a solid carbide jobber-length drill bit from the SD205A series, designed for high-performance drilling in demanding metal-cutting applications. It features a 140-degree point angle for reduced thrust and improved self-centering on entry, paired with a TiAlN (titanium aluminum nitride) coating that extends tool life under elevated cutting temperatures. The drill measures 14.90 mm in cutting diameter with a 133.00 mm overall length (approximately 5.24 inches) and is configured with a right-hand, spiral flute geometry. Two flutes and a standard point type make it well-suited for general-purpose production drilling. A straight-cylindrical shank with a 16.00 mm shank diameter ensures secure seating in standard drill chucks and toolholders.

This drill is intended for professional machining environments where close-tolerance hole-making is required in ferrous and hard materials. Typical applications include drilling into steel, stainless steel, cast iron, and other hard materials classified under ISO material groups P, M, K, and H. With a flute-to-diameter ratio of 5xD and a maximum drilling depth of 83.00 mm (approximately 3.27 inches), it fits production and job-shop drilling operations on CNC machining centers, drill presses, and manual mills. Coolant-through capability is not featured on this model, so external or flood coolant is recommended for deep-hole or high-speed applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlN coating improves heat resistance and extends cutting edge life compared to uncoated carbide
• 140-degree split point reduces walking and lowers thrust force at drill entry
• Right-hand spiral flute with regular helix promotes efficient chip evacuation in through-hole drilling
• Straight-cylindrical shank (16.00 mm diameter) compatible with standard ER collet chucks and keyless chucks
• Meets ANSI standards for dimensional accuracy; diameter tolerance class m7

Compatibility

Designed as a direct-fit replacement within the SECO SD205A series for drilling applications in steel, stainless steel, cast iron, and hard materials. Compatible with any machine spindle or toolholder accepting a 16.00 mm straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before inserting or removing the drill from the toolholder. Ensure the shank is fully seated and the collet or chuck is torqued to the toolholder manufacturer specification before operation. Inspect the cutting edges for chipping prior to each use, as carbide tooling is brittle and sensitive to lateral shock loads.
