Walter-titex 6618454 5/8 in Solid Carbide Jobber Drill Bit

Product Description

The WALTER-TITEX 6618454 is a jobber length drill bit engineered for demanding metal-cutting applications in professional machining environments. Built from solid carbide with a TiAlN (titanium aluminum nitride) coating, this bit delivers the heat and wear resistance required when drilling cast iron, non-ferrous metals, steel, and superalloys including titanium. The 140-degree split point geometry reduces thrust and walking at entry. At 5.2362 inches overall length with a 3.125-inch flute length, it fits standard jobber-length setups. The whistle notch shank at 0.6300 inches diameter provides positive retention in compatible tool holders. Coolant-through capability supports high-speed production runs where chip evacuation and thermal control are critical.

This drill bit is suited for blind hole drilling and stack drilling applications across ferrous and non-ferrous workpiece materials including cast iron, steel, superalloys, and titanium. Assigned material codes K, N, P, and S confirm its broad compatibility across these material groups. The Series DC150 designation identifies it within the WALTER-TITEX line of solid carbide drills designed for production-rate machining. It is installed and operated by machinists and tool-and-die professionals using CNC machining centers, drill presses, and multi-spindle setups where precision bore tolerances and high feed rates are required.

Key Features

• Solid carbide construction with TiAlN coating for extended tool life in high-heat cutting conditions
• 140-degree point angle reduces entry thrust and minimizes workpiece walking
• Coolant-through design supports chip evacuation and thermal management during deep or stack drilling
• Whistle notch shank provides positive retention and prevents shank rotation in tool holders
• Regular spiral flute geometry with 2 flutes promotes consistent chip flow
• Diameter tolerance m7 ensures precise bore sizing for close-tolerance applications
• Meets ANSI and ISO standards; UNSPSC 23241634

Compatibility

Designed for use with workpiece materials including cast iron, non-ferrous metals, steel, superalloys, and titanium (material codes K, N, P, S). Fits tool holders and chucks accepting a 0.6300-inch whistle notch shank. Part of the WALTER-TITEX DC150 Series for jobber-length solid carbide drills sized 0.5000 to 0.6500 inches in diameter.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with carbide tooling requirements. Ensure the machine spindle and tool holder are fully stopped and de-energized before loading or unloading the bit. Confirm the whistle notch is properly seated and the set screw is secured in the tool holder before operation. Avoid side loads or interrupted cuts that exceed the tool design parameters, as solid carbide is brittle and susceptible to chipping under shock loading.
