Walter-titex 7377931 Taper Length Drill Bit 15/32 in

Product Description

The WALTER-TITEX 7377931 is a solid carbide taper length drill bit engineered for high-performance drilling in demanding industrial and trade applications. Measuring 15/32 inch (0.4687 inch) in diameter, this bit features a 140-degree drill point angle and a TiSiAlCrN coating that extends tool life in abrasive and hard materials. The spiral flute geometry and right-hand cut are paired with through-coolant capability, making this bit suitable for deep, precise holes in production environments. It is installed by machinists, tool and die technicians, and maintenance tradespeople working with CNC and conventional drill presses.

This drill bit is designed for a wide range of drilling operations including blind hole, cross hole, inclined hole, stack drilling, and through hole drilling. The 8xD flute-to-diameter ratio supports deeper penetration with improved chip evacuation. Its parallel shank with a 12 mm shank diameter is compatible with standard collet and chuck systems used in CNC machining centers and industrial drill presses. The DIN 6537 K standard geometry ensures consistent dimensional accuracy across applications where tight tolerances are required.

Key Features

• Solid carbide construction in material grade WJ30ET for hardness and wear resistance
• TiSiAlCrN coating for extended tool life in abrasive and high-heat cutting conditions
• 140-degree drill point angle reduces thrust and improves centering on entry
• Through-coolant capable for heat management during deep-hole drilling
• 8xD flute length-to-diameter ratio supports maximum drilling depth of 96 mm (3.78 inches)
• Conforms to DIN 6537 K standards for consistent geometry and dimensional tolerance

Compatibility

Designed as an OEM-style replacement or direct-application drill bit for CNC machining centers and industrial drill presses accepting a 12 mm parallel shank with standard collet or chuck retention systems.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance tradespeople familiar with cutting tool setup and CNC or manual drill press operation. Ensure the spindle and coolant systems are fully powered down and depressurized before changing tooling. Verify collet size and runout tolerance before securing the parallel shank to maintain the m7 diameter tolerance specification. Always confirm coolant-through channels are clear and flow is established before beginning deep-hole drilling cycles.
