Walter-titex 7377538 Solid Carbide Jobber Drill 8.40 Mm

Product Description

The WALTER-TITEX 7377538 is a solid carbide jobber-length drill designed for high-performance hole-making in demanding materials. It features an 8.40 mm cutting diameter, a 140-degree split point, and a dual-layer AlTiN/TiSiAlCrN coating that resists heat and wear during aggressive drilling cycles. The straight-cylindrical shank measures 10.00 mm in diameter and seats directly in standard drill chucks or collet holders. At 103.00 mm overall length with a 61.00 mm flute length and a maximum drilling depth of 49.00 mm, this tool is sized for production and maintenance drilling in machining centers and drill presses. It is a tool for machinists and tool-and-die professionals working in environments where carbide tooling is standard.

This drill is rated for cast iron, non-ferrous metals, steel, superalloys, and titanium — material groups K, N, P, and S in ISO classification. The DC160 Series is built around a 5xD flute-to-diameter ratio, which supports chip evacuation in deeper holes. Supported hole types include blind holes, cross holes, inclined-hole exits, and stack drilling applications. Coolant-through capability allows internal coolant delivery to the cutting zone, making it well suited for high-speed machining cells where external coolant alone is insufficient.

Key Features

• Solid carbide construction with AlTiN/TiSiAlCrN dual-layer coating for extended tool life in hard and abrasive materials
• 140-degree point geometry reduces thrust force and improves self-centering at entry
• Coolant-through design delivers coolant directly to the cutting edge for heat control and chip flushing
• 5xD flute-to-diameter ratio supports chip evacuation in blind and deep holes up to 49.00 mm depth
• Right-hand spiral flutes with a 2-flute configuration for efficient chip removal
• Straight-cylindrical 10.00 mm shank with m7 diameter tolerance for precise chuck or collet fitment
• Compliant with ANSI and ISO standards; material grade WJ30ET

Compatibility

Designed for use in CNC machining centers, drill presses, and multi-spindle setups accepting a 10.00 mm straight-cylindrical shank. Suitable for workpiece materials classified under ISO material groups K, N, P, and S, including cast iron, non-ferrous metals, steel, superalloys, and titanium. Part of the WALTER-TITEX DC160 Series for carbide drilling applications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out state per applicable safety procedures. Seat the shank fully in the collet or chuck and verify runout before beginning a drilling cycle. When using coolant-through capability, confirm that the machine spindle and toolholder are configured for internal coolant delivery before engaging the coolant circuit. Inspect the cutting edges and coating condition before each use; carbide tooling is brittle and should not be used if chipping or cracking is visible on the flutes or point.
