Walter-titex 6618332 Solid Carbide Jobber Drill Bit 0.228 in

Product Description

The WALTER-TITEX 6618332 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding materials including cast iron, non-ferrous metals, steel, superalloys, and titanium. The bit measures 0.228 inches in diameter with an overall length of 3.228 inches and carries a TiAlN coating that extends tool life under elevated cutting temperatures. The 140-degree split point geometry reduces walking and thrust requirements at entry. Coolant-through capability supports chip evacuation in blind hole applications. This is a tool for professional machinists, metalworking shops, and maintenance technicians running CNC or manual drilling operations.

The 6618332 belongs to the WALTER-TITEX DC150 series, engineered for blind hole drilling and stack drilling applications. The whistle notch shank with a 0.236-inch shank diameter provides positive retention in standard collet and chuck systems. With a flute-by-diameter ratio of 5xD and a right-hand spiral flute, this bit maintains chip flow in interrupted cuts and multi-layer stack setups. It is suited for production environments where consistent hole tolerance and tool life are critical across ferrous and non-ferrous workpiece materials.

Key Features

• Solid carbide construction with TiAlN coating for extended tool life in abrasive and high-temperature materials
• 140-degree proprietary drill point reduces entry deflection and improves hole positioning accuracy
• Coolant-through design supports chip evacuation and thermal management in blind hole drilling
• Whistle notch shank provides positive drive engagement in collet and chuck systems
• 5xD flute-by-diameter ratio supports deep blind hole and stack drilling operations
• Meets ANSI and ISO standards with m7 diameter tolerance for consistent fit

Compatibility

Designed for use in CNC machining centers and manual drilling equipment where a 0.236-inch shank collet or chuck is available. Rated for cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces per WALTER-TITEX DC150 series specifications. Applicable to blind hole and stack drilling applications.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians with the spindle fully stopped and machine power isolated. Confirm collet or chuck bore matches the 0.236-inch shank diameter before seating the bit. Use the whistle notch feature with an appropriate retention system to prevent pull-out under cutting loads. Verify coolant-through passages are clear and system pressure is set per machine specifications before running production.
