Seco 03046411 Solid Carbide Jobber Drill 8.70 Mm Tialn

Product Description

The SECO 03046411 is a solid carbide jobber-length drill bit from the SD207A series, designed for high-performance drilling in demanding materials. It features an 8.70 mm cutting diameter, a 140-degree standard point angle, and a TiAlN coating that extends tool life by reducing heat buildup and wear at the cutting edge. The straight-cylindrical shank measures 10.00 mm in diameter, and the overall length is 122.00 mm (approximately 4.80 inches). This drill is intended for professional metalworking applications where precision and tool longevity are critical requirements.

This drill bit is suited for use in ferrous metals including steel, stainless steel, cast iron, and other hard materials, aligning with ISO material groups P, M, K, and H. It is a right-hand cutting, spiral-flute design with a regular spiral type, making it compatible with standard CNC machining centers, drill presses, and manual machines used in job shops, production facilities, and maintenance operations. The flute-to-diameter ratio of 8xD supports deeper hole applications within the 62.00 mm maximum drilling depth.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating reduces friction and thermal buildup, extending cutting tool life
• 140-degree point angle provides aggressive penetration and self-centering entry
• 8xD flute-to-diameter ratio allows drilling to a maximum depth of 62.00 mm (approximately 3.15 inches)
• Straight-cylindrical shank with 10.00 mm diameter fits standard collets and drill chucks
• Two-flute spiral design with no coolant-through requirement simplifies setup

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 10.00 mm straight-shank collet systems and drill chucks used in CNC and manual drilling applications targeting steel, stainless steel, cast iron, and hard material workpieces per ANSI standards.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals familiar with carbide tooling requirements. Ensure the machine spindle is fully stopped and secured before loading or removing the drill bit. Solid carbide tooling is brittle and should not be subjected to side loads or improper runout conditions — verify collet and chuck concentricity before running. Follow ANSI safety guidelines and machine manufacturer specifications for spindle speed and feed rate selection based on workpiece material.
