Walter-titex 6618329 Solid Carbide Jobber Drill Bit 0.219 in

Product Description

The WALTER-TITEX 6618329 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial and trade applications. With a 0.219-inch diameter, a 140-degree split-point geometry, and a TiAlN coating, this bit delivers extended tool life and thermal resistance in tough materials. The whistle notch shank provides positive engagement in compatible chucks, reducing slip under high torque loads. At 3.228 inches overall length with a 1.095-inch flute length, this is a compact, rigid tool suited for precision work in confined setups. Two spiral flutes with a regular helix efficiently evacuate chips during right-hand cutting operations.

This drill bit is engineered for use in cast iron, non-ferrous metals, steel, superalloys, and titanium — making it a strong choice for machine shops, aerospace component work, and heavy fabrication environments. It is rated for blind hole drilling and stack drilling applications. The DC150 series designation indicates suitability for general-purpose production drilling at moderate to high feed rates. The 5xD flute-to-diameter ratio supports stable chip flow without clogging in deeper passes up to the maximum drilling depth of 1.095 inches.

Key Features

• Solid carbide construction for rigidity and extended tool life in abrasive materials
• TiAlN coating provides heat and oxidation resistance at elevated cutting speeds
• 140-degree point angle with proprietary point type reduces thrust force and walking on entry
• Coolant-through capability supports internal coolant delivery for deep or high-speed operations
• Whistle notch shank (0.236 inches diameter) ensures secure chuck engagement
• Rated for blind hole and stack drilling applications per DC150 series design intent

Compatibility

The 6618329 belongs to the WALTER-TITEX DC150 series and is designed for use in CNC machining centers and drill presses accepting a 0.236-inch whistle notch shank. Primary workpiece material codes K, N, P, and S cover cast iron, non-ferrous metals, steel, and superalloys including titanium. Conforms to ANSI and ISO standards with an ISO specification designation and m7 diameter tolerance class.

Installation Notes

This tool is intended for installation by trained machinists or tooling technicians in a controlled shop environment. Secure the whistle notch shank fully into the chuck or collet before operation to prevent axial pull-out. When using the coolant-through feature, verify that the machine spindle coolant supply pressure and flow rate are compatible with the bit specifications before starting the cut. Inspect the cutting edges for chipping or coating wear before each use, as carbide tools can fail suddenly if operated with pre-existing damage.
