Walter-titex 7377456 5mm Solid Carbide Jobber Drill Bit

Product Description

The WALTER-TITEX 7377456 is a jobber length drill bit engineered for precision drilling in demanding industrial and trade applications. Built from solid carbide grade WJ30ET and finished with a dual TiSiAlCrN/AlTiN coating, this bit delivers high heat resistance and extended tool life in materials that wear down lesser tooling. The 5 mm diameter, 2-flute spiral flute design pairs with a 140-degree drill point angle to produce clean entry geometry across a wide range of workpiece materials. Coolant-through capability supports chip evacuation and thermal management at depth, making this bit a reliable choice for machinists and toolroom professionals who drill repetitive or high-tolerance holes.

This bit is suited for ferrous and non-ferrous machining environments including production shops, job shops, and maintenance operations. Rated applications include blind hole drilling, cross hole drilling, inclined hole exit, and stack drilling. Compatible workpiece materials include cast iron, non-ferrous metals, steel, superalloys, and titanium. The straight-cylindrical shank seats in standard drill chucks and collet holders without adapters. The Series DC160 designation places this bit within a well-established carbide jobber family built to ANSI and ISO standards.

Key Features

• Solid carbide construction with WJ30ET grade for hardness and wear resistance
• Dual TiSiAlCrN/AlTiN coating for high-temperature and oxidation resistance
• 140-degree drill point angle for reduced thrust and accurate hole entry
• Coolant-through design supports deep-hole chip evacuation and heat control
• Rated for blind holes, cross holes, inclined exits, and stack drilling
• Meets ANSI and ISO standards; 5xD flute-to-diameter ratio

Compatibility

Designed as a Series DC160 OEM-style solid carbide jobber drill bit compatible with cast iron, non-ferrous metal, steel, superalloys, and titanium workpieces. Fits standard drill chucks and collet holders accepting a 6 mm straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with CNC or manual drill press setup. Ensure the machine spindle is fully stopped and locked out before changing tooling. Confirm chuck or collet runout is within acceptable tolerance before seating the shank, as excessive runout accelerates carbide wear and can cause bit failure. Always verify coolant lines are clear and flowing before drilling at depth when using the coolant-through feature.
