Walter-titex 7684347 Extra Length Drill Bit 6mm Carbide

Product Description

The WALTER-TITEX 7684347 is a solid carbide extra length drill bit engineered for demanding precision drilling applications in metal fabrication and machining environments. It measures 6 mm in diameter with a 214 mm overall length and a 174 mm flute length, placing it in the DC160-25-A1 series with a 25xD flute-to-diameter ratio. The 140-degree point geometry reduces thrust load and improves self-centering on entry. A TiSiAlCrN coating provides heat resistance and extended tool life in high-temperature cutting conditions. This bit is designed for use by machinists and toolroom technicians working with CNC machining centers and drill presses requiring coolant-through capability.

This drill bit is suited for blind hole, cross hole, inclined hole exit, and stack drilling operations. Primary workpiece materials include alloy steel and titanium alloy. Secondary applications cover glass and graphite. The straight-cylindrical shank with h7 diameter tolerance ensures consistent runout in standard collet and chuck toolholding systems. It is a single-piece solid carbide construction — not brazed — making it appropriate for high-speed, high-precision production work where tool rigidity is critical.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiSiAlCrN coating for elevated heat resistance and extended cutting life
• 140-degree point angle reduces entry thrust and improves hole location accuracy
• Coolant-through design delivers cutting fluid directly to the tip for deep-hole drilling
• 25xD flute-to-diameter ratio supports maximum drilling depth of 165 mm
• Right-hand cutting, 2-flute design optimized for chip evacuation in deep holes
• Meets ANSI and ISO standards for dimensional and performance consistency

Compatibility

Designed for use in alloy steel and titanium alloy workpieces as primary materials, with secondary suitability for glass and graphite. Compatible with toolholding systems accepting a 6 mm straight-cylindrical shank with h7 tolerance. Verified for blind hole, cross hole, inclined hole exit, and stack drilling applications per series DC160-25-A1 specifications.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual drilling equipment. Ensure the machine spindle and toolholder are clean and free of debris before seating the shank. Activate coolant-through supply before commencing the cut to prevent tip overheating in deep-hole operations. Do not exceed the rated maximum drilling depth of 165 mm without re-evaluating chip evacuation and coolant pressure for the specific setup.
