Walter-titex 7377654 Solid Carbide Jobber Drill 13.30 Mm

Product Description

The WALTER-TITEX 7377654 is a solid carbide jobber-length twist drill engineered for high-performance hole-making in demanding industrial and metalworking applications. It carries a dual-layer AlTiN/TiSiAlCrN coating that resists heat and wear at elevated cutting speeds. The 140-degree split point geometry promotes self-centering entry and reduces thrust force at the cut. At 13.30 mm in diameter with a 124.00 mm overall length and 77.00 mm flute length, this drill is dimensioned for the DC160 series 5xD flute-to-diameter ratio. It is sized for machine tool spindles and CNC setups where tight hole tolerances are required. Licensed machinists and CNC operators are the primary users of this tool.

This drill is suited for production drilling in cast iron, non-ferrous metals, carbon and alloy steels, superalloys, and titanium. Its coolant-through design supports internal coolant delivery, making it appropriate for deep-hole work in CNC machining centers. Typical applications include blind holes, cross holes, inclined-hole exits, and stack drilling operations where consistent chip evacuation and hole quality are critical. The straight-cylindrical shank fits standard ER and hydraulic toolholders commonly used in vertical and horizontal machining centers.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• AlTiN/TiSiAlCrN dual-layer coating provides thermal stability and extended tool life at high cutting speeds
• 140-degree point angle reduces entry thrust and improves self-centering on flat and curved surfaces
• Coolant-through capability supports chip flushing and heat management in blind and deep holes
• 5xD flute-by-diameter ratio with a maximum drilling depth of 60.00 mm
• Right-hand spiral flute with two flutes for efficient chip evacuation across material grades P, K, N, and S
• Meets ANSI and ISO standards; material grade WJ30ET; diameter tolerance m7

Compatibility

Designed for use in CNC machining centers and drill presses equipped with toolholders accepting a 14.00 mm straight-cylindrical shank. Compatible workpiece material codes include P (steel), K (cast iron), N (non-ferrous metals), and S (superalloys and titanium) per ISO designation. Part of the WALTER-TITEX DC160 series.

Installation Notes

Installation and operation of this drill should be performed by qualified machinists or CNC programmers familiar with carbide tooling parameters. Ensure the spindle and toolholder are clean and properly torqued before seating the shank. Activate coolant-through flow before the drill contacts the workpiece to prevent thermal shock to the carbide substrate. Avoid running carbide drills in worn or loose spindles, as runout accelerates edge chipping and reduces tool life.
