Walter-titex 6618330 Solid Carbide Jobber Drill Bit

Product Description

The WALTER-TITEX 6618330 is a solid carbide jobber length drill bit designed for precision hole-making in demanding industrial and machining applications. Built to Series DC150 standards, this bit features a TiAlN (titanium aluminum nitride) coating that extends tool life and maintains cutting performance at elevated temperatures. The 140-degree drill point angle reduces thrust force and improves centering without a pilot hole. With a 0.22 inch diameter, a whistle notch shank, and a right-hand spiral flute configuration, it is suited for production drilling where accuracy and repeatability are required. Licensed machinists and toolroom technicians are the primary users of this tooling.

This drill bit is engineered for use in blind hole drilling and stack drilling operations. Its 5xD flute-to-diameter ratio supports chip evacuation in deeper cuts. Compatible workpiece materials include cast iron, non-ferrous metals, steel, superalloys, and titanium. Coolant-through capability allows internal coolant delivery, making it appropriate for CNC machining centers and high-speed production environments where heat management is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating improves heat resistance and extends cutting tool life
• 140-degree split point reduces walking and lowers axial thrust
• Coolant-through design supports internal coolant delivery for deep or high-speed drilling
• Whistle notch shank provides positive drive and reduces slippage in collet chucks
• Right-hand spiral flute promotes efficient chip evacuation

Compatibility

Designed for use in CNC machining centers and drill presses capable of accepting a 0.236 inch shank. Suitable for machining cast iron, non-ferrous metals, steel, superalloys, and titanium per the Series DC150 application guidelines. Conforms to ANSI and ISO standards.

Installation Notes

Install this bit into a compatible collet or chuck rated for the 0.236 inch whistle notch shank diameter and confirm secure seating before spindle engagement. Power down and lock out the machine before changing tooling. Set coolant flow and spindle speed according to the workpiece material and machine manufacturer specifications. Inspect the cutting edges for wear or chipping before each use and replace if edge integrity is compromised.
