Walter-titex 7377593 27/64 Inch Carbide Drill Bit DC160

Product Description

The WALTER-TITEX 7377593 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding industrial and trade applications. It carries a dual-layer TiSiAlCrN/AlTiN coating that extends tool life and supports higher cutting speeds across difficult materials. The drill measures 27/64 inch (0.4219 inch) in diameter with a 140-degree split point angle for accurate entry and reduced thrust. Overall length is 118 mm with a flute length of 71 mm and a maximum drilling depth of 56 mm. The straight-cylindrical shank measures 12 mm in diameter. This bit is part of the Series DC160 product line and is built to ANSI and ISO standards. Installation and use are suited to machinists, toolroom professionals, and maintenance technicians working with CNC or manual drilling equipment.

This drill bit is engineered for use in cast iron, non-ferrous metals, steel, superalloys, and titanium. Its 5xD flute-to-diameter ratio and spiral flute design promote consistent chip evacuation across a range of hole types. Supported tool applications include blind holes, cross holes, inclined hole exits, and stack drilling. The coolant-through design allows internal coolant delivery directly to the cutting zone, making it well-suited for deep-hole work in tough materials where heat buildup and chip packing are primary concerns. It performs reliably in both high-volume production and precision maintenance environments.

Key Features

• Solid carbide construction in material grade WJ30ET for wear resistance in ferrous and non-ferrous materials
• TiSiAlCrN/AlTiN dual coating reduces friction and extends cutting life at elevated temperatures
• 140-degree drill point angle improves self-centering and reduces walking on entry
• Coolant-through capability delivers cutting fluid directly to the tip for heat control and chip removal
• Right-hand spiral flute design with 5xD ratio supports efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

The 7377593 is rated for use in cast iron, non-ferrous metals, steel, superalloys, and titanium workpiece materials (material codes K, N, P, S). It is designed for tool applications including blind holes, cross holes, inclined hole exits, and stack drilling as specified by the manufacturer.

Installation Notes

This drill bit should be installed and operated by qualified machinists or maintenance technicians familiar with cutting tool specifications and machine tool operation. Confirm the spindle, chuck, or collet holder is rated for the 12 mm shank diameter before mounting. Ensure the machine is fully powered down and locked out before changing tooling. When using the coolant-through feature, verify that coolant pressure and flow rate are appropriate for the machine spindle to avoid thermal shock to the carbide substrate.
