Walter-titex 7377499 Carbide Jobber Drill 6.80mm DC160

Product Description

The WALTER-TITEX 7377499 is a solid carbide jobber-length twist drill designed for high-performance hole-making in demanding production environments. Measuring 6.80 mm in diameter with a 140-degree split point, the drill delivers clean entry with reduced thrust and minimal walking on curved or inclined surfaces. The dual AlTiN and TiSiAlCrN coating stack provides heat resistance and edge retention at elevated cutting speeds. With an overall length of 91.00 mm, a flute length of 53.00 mm, and a maximum drilling depth of 43.00 mm, this tool is suited for machinists and tooling professionals running CNC or manual drilling operations at high feeds.

The DC160 series is engineered for blind holes, cross holes, inclined hole exits, and stack drilling applications. Primary workpiece materials include cast iron, non-ferrous metals, steel, superalloys, and titanium, covering ISO material codes K, N, P, and S. The straight-cylindrical shank measures 8.00 mm in diameter and 36.00 mm in length, fitting standard collets and drill chucks. Coolant-through capability supports high-speed machining cycles where chip evacuation and thermal management are critical. This drill is a practical choice for aerospace, automotive, and general machining shops that require consistent hole geometry across difficult-to-machine alloys.

Key Features

• Solid carbide construction in material grade WJ30ET for rigidity and edge life in hard materials
• Dual-layer AlTiN and TiSiAlCrN coating for high heat resistance and extended tool life
• 140-degree point angle reduces entry thrust and improves centering on uneven surfaces
• Coolant-through design supports high-speed drilling and efficient chip removal in deep holes
• Spiral flute geometry with 5xD flute-to-diameter ratio handles blind holes, cross holes, inclined exits, and stack drilling
• Conforms to ANSI and ISO standards for dimensional consistency and interchangeability

Compatibility

Designed for use in CNC machining centers and drilling equipment accepting an 8.00 mm straight-cylindrical shank. Suitable for cast iron, non-ferrous metals, carbon and alloy steels, superalloys, and titanium workpieces per ISO material codes K, N, P, and S.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Verify collet or chuck bore matches the 8.00 mm shank diameter before clamping to ensure concentricity and prevent runout. When enabling coolant-through supply, confirm the machine spindle supports internal coolant delivery at the required pressure. Follow the tool manufacturer's recommended cutting parameters for the specific workpiece material to avoid premature edge wear or tool breakage.
