Walter-titex 6618419 Solid Carbide Jobber Drill 0.4920 in

Product Description

The WALTER-TITEX 6618419 is a solid carbide jobber drill engineered for high-performance hole-making in demanding metalworking applications. Measuring 0.4920 inches in diameter with a 140-degree point angle, this drill is TiAlN coated for extended tool life and heat resistance at elevated cutting speeds. The whistle notch shank seats securely in compatible toolholders, and the two-flute spiral design promotes efficient chip evacuation. Overall length is 4.8819 inches with a maximum drilling depth of 2.4600 inches. It is part of the DC150 series and is suitable for use by machinists and tool-room professionals working on CNC machining centers and drill presses.

This drill is rated for use in cast iron, non-ferrous metals, steel, superalloys, and titanium. It supports blind hole drilling and stack drilling applications, making it a practical choice for production environments where multiple material types appear on the same floor. The 5xD flute-to-diameter ratio provides rigidity while maintaining adequate flute length for chip clearance. Coolant-through capability allows internal coolant delivery for improved chip flushing and thermal management during deep or interrupted cuts.

Key Features

• Solid carbide construction with TiAlN coating for wear resistance and heat tolerance
• 140-degree point angle reduces entry thrust and improves self-centering on hard materials
• Coolant-through design supports internal coolant delivery for blind hole and stack drilling
• Whistle notch shank provides positive drive and prevents shank rotation in toolholder
• 5xD flute-to-diameter ratio balances rigidity with maximum drilling depth of 2.4600 inches
• Meets ANSI and ISO standards with diameter tolerance class m7

Compatibility

Designed for use in cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces. The 0.5510-inch shank diameter is compatible with standard toolholders accepting whistle notch shanks in that size range. Part of the WALTER-TITEX DC150 series, covering the 0.4000 to 0.5000 inch drill bit size range.

Installation Notes

Installation and operation should be performed by a qualified machinist or toolroom professional. Ensure the machine spindle and toolholder are powered down and fully stopped before inserting or removing the drill. Confirm the toolholder bore matches the 0.5510-inch shank diameter and that coolant-through connections are properly engaged if internal coolant is used. Do not exceed the maximum drilling depth of 2.4600 inches as specified for this tool.
