Walter-titex 6618440 Solid Carbide Jobber Drill 0.5710 in

Product Description

The WALTER-TITEX 6618440 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production environments. It features a 0.5710 inch (14.50 mm) cutting diameter with a 140-degree point angle and a TiAlN (titanium aluminum nitride) coating that extends tool life at elevated cutting temperatures. The overall length is 5.2362 inches (133.00 mm) and the flute length reaches 2.8550 inches (72.52 mm), providing a 5xD depth-to-diameter ratio. A whistle notch shank with a 0.6300 inch (16 mm) diameter ensures positive retention in compatible toolholders. This drill is suited for licensed machinists and CNC setup technicians working in job shops, aerospace, and general metalworking operations.

The 6618440 is engineered for right-hand cutting with a regular spiral flute configuration. It is rated for blind hole drilling and stack drilling applications in steel, cast iron, aluminum, and other non-ferrous materials. The proprietary point geometry and TiAlN coating make it particularly effective in abrasive and high-tensile materials where standard HSS tooling wears prematurely. Coolant-through capability supports extended tool life and chip evacuation in deeper cuts. This bit belongs to the WALTER-TITEX DC150 series and is classified as a high-performance grade drill per ISO specification designation.

Key Features

• Solid carbide construction with TiAlN coating for extended wear resistance in steel and cast iron
• 140-degree proprietary point angle reduces thrust force and improves centering accuracy
• Coolant-through design supports chip evacuation and thermal management in blind hole applications
• Whistle notch shank (0.6300 inch diameter) provides secure positive drive in compatible toolholders
• 5xD flute-to-diameter ratio allows drilling up to 2.8550 inches deep without tool change
• Rated for blind hole and stack drilling in steel, cast iron, aluminum, and non-ferrous materials

Compatibility

Designed for use with toolholders and chucks that accept a 0.6300 inch (16 mm) whistle notch shank. Suitable for CNC machining centers and drill presses configured for coolant-through tooling. Rated for primary workpiece material codes K, N, P, and S per ISO classification, covering cast iron, non-ferrous, steel, and superalloy material groups. Part of the WALTER-TITEX DC150 series.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC technician. Confirm the machine spindle and toolholder are rated for the shank diameter and coolant-through pressure before use. Ensure the machine is fully stopped and de-energized before loading or removing the drill from the toolholder. Follow the tool manufacturer's recommended cutting parameters for speed and feed based on workpiece material; do not exceed the drill's rated maximum drilling depth of 2.8550 inches per plunge.
