Walter-titex 7684323 Extra Length Drill Bit 7/16 in

Product Description

The WALTER-TITEX 7684323 is a solid carbide extra length drill bit engineered for high-performance drilling in demanding materials. Measuring 7/16 inch (11.11 mm) in diameter with a 140-degree split point, this bit delivers precise entry and reduced thrust across a range of workpiece materials. The TiSiAlCrN coating extends tool life in abrasive and high-temperature cutting environments. With a flute length of 10.394 inches (264 mm) and an overall length of 12.244 inches (311 mm), the 7684323 is designed for deep-hole and extended-reach applications where standard-length bits fall short. Coolant-through capability supports chip evacuation and thermal management at depth. Licensed machinists, tool-and-die professionals, and industrial maintenance mechanics are the primary installers and operators of this tooling.

This drill bit is suited for blind hole, cross hole, inclined hole exit, and stack drilling operations. Primary workpiece materials include alloy steels and titanium alloys. Secondary workpiece material compatibility covers glass and graphite. The straight-cylindrical shank with a 0.472-inch (12 mm) shank diameter fits standard tool holders and collet chucks. The Series DC160-20-A1 designation places this bit in the 20xD flute-to-diameter ratio category, confirming its deep-drilling design intent. A right-hand cutting direction is standard. The 7684323 conforms to ANSI and ISO standards.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiSiAlCrN coating for extended tool life in high-temperature cutting conditions
• 140-degree drill point angle reduces thrust and minimizes workpiece distortion on entry
• Coolant-through design supports chip evacuation and heat management at drilling depth
• 20xD flute-to-diameter ratio enables deep-hole drilling up to 9.685 inches (246 mm) maximum depth
• Drill bit diameter tolerance of h7 ensures accurate, repeatable hole sizing
• Compatible with blind hole, cross hole, inclined hole exit, and stack drilling operations

Compatibility

Designed for use with alloy steels and titanium alloys as primary workpiece materials; secondary materials include glass and graphite. Conforms to ANSI and ISO standards. Fits tool holders and collet chucks accepting a 0.472-inch (12 mm) straight-cylindrical shank. Part of the WALTER-TITEX DC160-20-A1 series.

Installation Notes

Installation and operation should be performed by qualified machinists or tooling specialists familiar with carbide drill bit setup and CNC or manual machine tool operation. Ensure the machine spindle is fully stopped and de-energized before mounting or removing the bit. Verify coolant-through supply lines are connected and functioning before drilling at extended depth. Do not exceed the rated maximum drilling depth of 9.685 inches (246 mm) to avoid tool deflection or breakage.
