Walter-titex 6618299 Solid Carbide Jobber Drill 0.1340 in

Product Description

The WALTER-TITEX 6618299 is a solid carbide jobber-length drill bit with a 140-degree split point and TiAlN coating, designed for high-performance hole-making in demanding industrial and metalworking applications. The bit measures 0.1340 inches in diameter with an overall length of 2.5984 inches (66.00 mm) and a whistle notch shank. The DC150 series design integrates a proprietary point geometry and spiral flute configuration to deliver consistent chip evacuation and extended tool life when drilling hard and abrasive materials. Coolant-through capability supports high-speed machining operations. Licensed machinists and CNC operators in job shop and production environments are the primary users of this tool.

This drill is suited for blind hole drilling and stack drilling applications across a range of workpiece materials, including cast iron, non-ferrous metals, steel, superalloys, and titanium. The 5xD flute-to-diameter ratio supports drilling depths up to 0.6700 inches (17.02 mm). Its two-flute spiral configuration and right-hand cutting direction make it compatible with standard vertical mills, CNC machining centers, and drill presses equipped for coolant delivery. The whistle notch shank diameter of 0.2360 inches facilitates secure tool holding in compatible chucks and collet systems.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating extends tool life under high heat and cutting-speed conditions
• 140-degree proprietary point reduces thrust force and improves hole entry accuracy
• Coolant-through design supports high-speed and deep-hole drilling cycles
• Whistle notch shank prevents tool pullout under high-torque conditions
• Meets ANSI and ISO standards per specification designation ISO

Compatibility

Designed as an OEM-style replacement and standard production drill for use in machining centers and drill presses that accept whistle notch shank tooling. Compatible workpiece materials include cast iron, non-ferrous metals, steel, superalloys, and titanium per material codes K, N, P, and S.

Installation Notes

Installation and use of this drill should be performed by qualified machinists or CNC technicians. Ensure the machine spindle is fully stopped and the tool changer or chuck is de-energized before loading or unloading the bit. Verify that the collet or chuck is rated for the 0.2360-inch shank diameter and that coolant lines are clear before initiating a through-coolant cycle. Follow ANSI and ISO tool-holding guidelines for proper runout and clamping torque to prevent premature tool failure.
