Walter-titex 6618645 Solid Carbide Jobber Drill Bit 5.5 Mm

Product Description

The WALTER-TITEX 6618645 is a solid carbide jobber-length drill bit engineered for precision drilling in demanding industrial and machining applications. Ground to a 140-degree drill point angle and finished with a TiNAl coating, this bit delivers extended tool life and thermal resistance in high-speed cutting environments. The straight-cylindrical shank measures 6.00 mm in diameter and 36.00 mm in length, with an overall length of 97.00 mm (3.819 inches). A two-flute geometry with an 8xD flute-to-diameter ratio supports efficient chip evacuation in both blind hole and stack drilling operations. Licensed machinists and CNC operators are the primary installers of this tooling.

This drill bit is designed for use in blind hole and stack drilling applications across cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces. The TiNAl coating and WJ30TA carbide grade make it well-suited for production-level machining where heat generation and tool wear are primary concerns. It conforms to ANSI and ISO standards, fitting within the DC150-08-A1 series. Applicable in both manual and CNC machine setups where consistent hole diameter tolerance at m7 is required.

Key Features

• Solid carbide construction in WJ30TA grade for rigidity and wear resistance in hard materials
• TiNAl coating provides thermal barrier and extended cutting life at elevated spindle speeds
• 140-degree drill point angle reduces thrust force and is optimized for hard and abrasive workpiece materials
• Coolant-through design supports internal coolant delivery for deep or high-feed drilling
• Straight-cylindrical shank compatible with standard collet and drill chuck systems
• Supports blind hole and stack drilling applications per tool specification

Compatibility

Designed as a DC150-08-A1 series jobber-length drill bit suitable for CNC machining centers and drilling machines configured for 6.00 mm straight-cylindrical shank tooling. Compatible workpiece materials per manufacturer specification include cast iron, non-ferrous metals, steel, superalloys, and titanium.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the machine in a fully de-energized and locked-out state per applicable safety procedures. Ensure the collet or chuck bore is clean and within tolerance before seating the shank. Do not exceed the maximum drilling depth of 48.00 mm (1.890 inches) as specified for this tool. Verify coolant-through compatibility with the machine spindle before activating internal coolant delivery.
