Walter-titex 7377633 Carbide Jobber Drill 31/64 Inch

Product Description

The WALTER-TITEX 7377633 is a solid carbide jobber-length drill bit designed for high-performance hole-making in demanding industrial and machining applications. Built to Series DC160 standards, it features a 31/64 inch (0.4844 inch decimal) diameter, a 140-degree split point, and a dual-layer AlTiN/TiSiAlCrN coating that extends tool life under elevated cutting temperatures. The straight-cylindrical shank and right-hand spiral flute geometry promote chip evacuation and dimensional accuracy. This drill is installed by machinists and tool-room professionals running CNC machining centers or manual drill presses where tight tolerances and consistent hole quality are required.

The 7377633 is suited for drilling blind holes, cross holes, inclined hole exits, and stack drilling operations. Its coolant-through design supports high-speed cutting strategies by delivering coolant directly to the cutting edge. Primary workpiece materials include cast iron, non-ferrous metals, steel, superalloys, and titanium, covering a broad range of production and job-shop scenarios where carbide tooling is specified over high-speed steel.

Key Features

• Solid carbide construction with AlTiN/TiSiAlCrN dual-layer coating for heat and wear resistance
• 140-degree point angle reduces thrust force and improves self-centering on entry
• Coolant-through design delivers cutting fluid directly to the tip for deep-hole and high-speed applications
• Right-hand spiral flute promotes efficient chip evacuation
• 5xD flute-to-diameter ratio supports maximum drilling depth of 60 mm
• Compliant with ANSI and ISO standards; material grade WJ30ET

Compatibility

Designed for use in CNC machining centers and drill presses accepting a straight-cylindrical shank; suitable for cutting cast iron, non-ferrous metals, steel, superalloys, and titanium workpieces per material codes K, N, P, and S.

Installation Notes

Installation and setup should be performed by qualified machinists or tooling technicians. Ensure the machine spindle and tool holder are fully de-energized and locked out before inserting or removing the drill. Verify shank seating and runout with a dial indicator before beginning a production run. Use appropriate cutting parameters and coolant pressure for the workpiece material to avoid premature coating wear or chipping.
