Walter-titex 6618322 Solid Carbide Jobber Drill Bit 0.201 in

Product Description

The WALTER-TITEX 6618322 is a solid carbide jobber length drill bit engineered for high-performance drilling in demanding materials. Coated with TiAlN for extended tool life and heat resistance, it features a 140-degree drill point angle optimized for reduced thrust and accurate entry. The whistle notch shank provides positive drive retention in compatible chuck systems. At 3.228 inches overall length with a 1.005-inch flute length, this bit handles blind hole and stack drilling applications where precision and rigidity are required. Coolant-through capability supports chip evacuation and thermal control during deep-cut operations. It is sold individually and is appropriate for use by machining professionals and production maintenance trades.

This drill bit is designed for use in cast iron, non-ferrous metals, steel, superalloys, and titanium. The DC150 series targets applications where tool life and hole quality are critical, including blind hole drilling and stack drilling setups. The regular spiral flute geometry and two-flute configuration promote efficient chip flow across this range of workpiece materials. Its 5xD flute-to-diameter ratio supports consistent cutting performance in typical machining center and drill press applications.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists or maintenance professionals familiar with machine tool setups. Confirm that the spindle and chuck system are fully powered down and locked out before changing tooling. Verify chuck compatibility with the whistle notch shank style and 0.236-inch shank diameter before mounting. Follow machine tool manufacturer guidelines for spindle speed and feed rate selection based on workpiece material and hole depth.
