Walter-titex 6618424 Solid Carbide Jobber Drill Bit 0.512in

Product Description

The WALTER-TITEX 6618424 is a solid carbide jobber-length drill bit with a TiAlN coating, designed for high-performance drilling in demanding industrial and machining applications. This right-hand-cut drill features a 140-degree point angle and a whistle notch shank, with an overall length of 4.882 inches and a flute length of 2.56 inches. The TiAlN finish extends tool life when cutting harder materials at elevated temperatures. Belonging to the DC150 series, this bit is engineered for consistent hole quality in blind-hole and stack-drilling applications.

This drill bit is suited for machining cast iron, non-ferrous metals, steel, superalloys, and titanium. Its coolant-through design makes it a strong candidate for CNC machining centers and automated drilling operations where internal coolant delivery is available. The 5xD flute-to-diameter ratio and regular spiral flute geometry support efficient chip evacuation in both shallow and moderate-depth holes. It is typically used by machinists and tooling professionals in production environments requiring tight tolerances.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating for enhanced heat resistance and extended tool life
• 140-degree point angle for reduced thrust and improved centering on entry
• Coolant-through design supports internal coolant delivery for deep or high-speed drilling
• Whistle notch shank for secure chuck engagement and accurate drive
• Rated for blind-hole and stack-drilling applications per DC150 series specifications

Compatibility

Designed for use with CNC machining centers and drilling setups capable of accepting a 0.551-inch whistle notch shank. Compatible primary 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 should be performed by qualified machinists familiar with carbide tooling and CNC or manual drill press operation. Ensure the machine spindle and chuck are fully de-energized and locked out before securing or removing the bit. Verify that the tool holder is compatible with a whistle notch shank style and the specified 0.551-inch shank diameter before clamping. Carbide drill bits should not be used without adequate chip clearance or coolant flow, as overheating can cause micro-fractures in the carbide substrate.
