Walter-titex 6618305 Solid Carbide Jobber Drill Bit

Product Description

The WALTER-TITEX 6618305 is a solid carbide jobber length drill bit designed for precision drilling in demanding industrial and trade applications. Measuring 0.15 inches in diameter with an overall length of 2.9134 inches, this bit features a TiAlN coating that extends tool life under high heat and abrasive cutting conditions. The 140-degree drill point angle and regular spiral flute geometry deliver clean entry and efficient chip evacuation. It is part of the DC150 series and is suited for professionals requiring consistent, repeatable performance in production and maintenance environments.

This drill bit is engineered for use in blind hole and stack drilling applications across a range of workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. The whistle notch shank and 0.2360-inch shank diameter provide secure tool holding in compatible chucks and tool holders. Coolant-through capability supports extended run times in high-cycle machining setups. It is well-suited for machinists, toolroom technicians, and maintenance professionals working with CNC equipment or conventional drill presses.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating provides thermal protection and extended cutting life
• 140-degree drill point angle reduces thrust and improves centering accuracy
• Coolant-through design supports high-cycle and deep-hole drilling efficiency
• Whistle notch shank prevents tool pullout during drilling operations
• Regular spiral flute with 5xD flute-to-diameter ratio for effective chip removal

Compatibility

Designed for use with workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. The whistle notch shank with a 0.2360-inch shank diameter is compatible with tool holders designed for that shank style and diameter. Suitable for blind hole and stack drilling applications per DC150 series specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom professionals familiar with proper tool holding and speeds and feeds for carbide tooling. Before mounting, confirm the tool holder is clean, undamaged, and rated for the shank diameter. Power down and de-energize the machine spindle before inserting or removing the bit. Do not exceed the maximum drilling depth of 0.75 inches as specified for this tool.
