Walter-titex 7377480 Carbide Drill Bit 15/64 in 140 Deg

Product Description

The WALTER-TITEX 7377480 is a solid carbide jobber length drill bit designed for demanding metal-cutting applications in production and machining environments. It measures 15/64 inches (0.2344 inches) in diameter with a 140-degree point angle optimized for self-centering entry and reduced thrust. The bit carries a dual-layer AlTiN and TiSiAlCrN coating that resists heat and wear at elevated cutting speeds. Overall length is 82.00 mm with a flute length of 44.00 mm and a 5xD flute-to-diameter ratio. A straight-cylindrical shank with a 6.00 mm diameter and 36.00 mm shank length fits standard chucks and tool holders. Coolant-through capability supports high-speed, deep-hole strategies. This tool is intended for use by machinists and CNC operators in industrial toolroom and production settings.

The 7377480 is built for cutting cast iron, non-ferrous metals, steel, superalloys, and titanium. Its Series DC160 design addresses a range of hole-making strategies including blind holes, cross holes, inclined hole exits, and stack drilling. Maximum drilling depth is 35.00 mm. The right-hand spiral flute geometry promotes efficient chip evacuation in both ferrous and non-ferrous materials, making this bit suitable for multi-material setups common in aerospace, automotive, and general metalworking production lines.

Key Features

• Solid carbide construction for rigidity and tool life in hard and abrasive materials
• Dual-coating AlTiN and TiSiAlCrN for high-temperature wear resistance
• 140-degree point angle reduces walking and lowers required thrust force
• Coolant-through design supports high-speed and deep-hole drilling strategies
• 5xD flute-to-diameter ratio with 2 spiral flutes for reliable chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collet systems
• Rated for cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces

Compatibility

Designed for use with materials coded K (cast iron), N (non-ferrous metals), P (steel), and S (superalloys and titanium) per ISO workpiece material classification. Suitable for blind hole, cross hole, inclined hole exit, and stack drilling applications. Diameter tolerance class m7. Conforms to ANSI and ISO standards.

Installation Notes

This tool is installed and operated by machinists or CNC operators using standard drill chucks or collet holders sized for a 6.00 mm straight-cylindrical shank. Verify spindle speed and feed rate against the material being cut before starting; running solid carbide at incorrect parameters accelerates breakage. Connect coolant-through supply lines before engaging high-speed cycles. Inspect the cutting edges and coating condition before each use — carbide is brittle and should not be forced into interrupted cuts without confirming the tool is free of chips or micro-fractures.
