Walter-titex 6618293 Solid Carbide Jobber Drill Bit 0.118 in

Product Description

The WALTER-TITEX 6618293 is a solid carbide jobber-length drill bit engineered for precision hole-making in demanding materials. It carries a TiAlN coating for elevated heat and wear resistance, making it well-suited to high-speed cutting applications. The 140-degree split point reduces walking on entry and lowers thrust requirements. Overall length is 2.598 inches, with a 0.590-inch flute length and a 0.118-inch cutting diameter. The whistle notch shank seats firmly in tool holders to minimize runout. This bit is designed for use by machinists and CNC operators who need consistent, repeatable hole quality across production runs.

The 6618293 targets blind-hole drilling and stack drilling in cast iron, non-ferrous metals, steel, superalloys, and titanium. Its 5xD flute-to-diameter ratio and regular spiral geometry support efficient chip evacuation in these material families. The through-coolant capability allows cutting fluid to reach the tip directly, reducing heat buildup and extending tool life in deeper cuts. It fits standard ER and milling collet chucks sized for a 0.236-inch shank diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiAlN coating extends tool life at elevated cutting temperatures
• 140-degree point angle reduces entry walking and lowers required thrust
• Through-coolant design delivers fluid directly to the cutting edge
• Whistle notch shank provides positive drive and reduces slippage in the holder
• Qualified for blind-hole and stack drilling applications per ANSI and ISO standards

Compatibility

Designed as an OEM-style replacement or direct tooling selection in the WALTER-TITEX DC150 series, compatible with collet chucks and tool holders accepting a 0.236-inch whistle notch shank.

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with carbide tooling requirements. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Carbide is brittle — avoid side loads, interrupted cuts beyond the tool rating, or re-chucking with worn or contaminated collets, as these conditions can cause sudden breakage. Activate through-coolant flow before the cutting edge contacts the workpiece to prevent thermal shock to the coating.
