Walter-titex 6618320 Jobber Drill Bit 0.193 in Carbide DC150

Product Description

The WALTER-TITEX 6618320 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial and trade applications. It measures 0.193 inches in diameter with an overall length of 3.228 inches (82 mm), a whistle notch shank diameter of 0.236 inches, and carries a TiAlN coating for extended tool life in abrasive materials. The 140-degree drill point angle and two-flute spiral configuration provide aggressive chip evacuation and precise entry geometry. Coolant-through capability supports sustained cutting speeds in deep-hole and production drilling environments. Machinists, tool-and-die technicians, and maintenance professionals working in metal fabrication or industrial maintenance rely on this bit for consistent hole quality across a range of ferrous and non-ferrous materials.

The 6618320 is rated for use in cast iron, non-ferrous metals, steel, superalloys, and titanium, making it suitable for aerospace, automotive, and general metalworking applications. The DC150 series designation places it in a high-performance jobber-length carbide line engineered for both blind hole drilling and stack drilling operations. The 5xD flute-by-diameter ratio supports a maximum drilling depth of 0.965 inches (24.51 mm), appropriate for through-holes and shallow blind holes in production or maintenance settings.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard materials
• TiAlN coating reduces wear and extends tool life in steel, superalloys, and titanium
• 140-degree point angle with proprietary point geometry for self-centering entry
• Coolant-through design supports high-speed production drilling and heat management
• Whistle notch shank provides positive retention in compatible tool holders
• Compliant with ANSI and ISO standards per ISO specification designation

Compatibility

Designed as a DC150 series jobber length carbide drill bit rated for cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces. Whistle notch shank is compatible with tool holders engineered for 0.236-inch shank diameters.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle and tool holder are fully stopped and de-energized before changing or seating the bit. Verify that the coolant-through supply is properly connected and flowing before running at elevated speeds. Do not exceed the rated maximum drilling depth of 0.965 inches without re-evaluating chip evacuation and coolant flow conditions.
