Walter-titex 7378435 Carbide Jobber Drill 0.1378 in

Product Description

The WALTER-TITEX 7378435 is a solid carbide jobber-length drill bit designed for high-performance hole-making in ferrous materials. It features a 140-degree split point, a dual-layer AlTiN and TiSiAlCrN coating, and a right-hand cutting direction. The 0.1378-inch diameter and straight-cylindrical shank make it compatible with standard drill chucks and collet holders. With an overall length of 2.5980 inches and a flute length of 1.1020 inches, this bit is built for precision drilling in tight tolerances. It is sized to a m7 diameter tolerance and manufactured to ANSI and ISO standards. Machinists and tool-and-die technicians are the primary users.

This drill is suited for production and maintenance machining on cast iron and steel workpieces. Application types include blind holes, cross holes, inclined hole exits, and stack drilling. The 5xD flute-to-diameter ratio supports a maximum drilling depth of 0.9060 inches. The shank diameter of 0.2360 inches and shank length of 1.4170 inches provide solid tool engagement in standard toolholders. It is well-suited for CNC machining centers and manual drill presses operating in job shop or manufacturing environments where close-tolerance hole placement is required.

Key Features

• Solid carbide construction in material grade WJ30ET for rigidity and wear resistance in ferrous materials
• Dual-layer AlTiN and TiSiAlCrN coating extends tool life in cast iron and steel applications
• 140-degree point geometry reduces thrust and improves centering without a pilot hole
• Right-hand cut, straight-cylindrical shank fits standard collets and drill chucks
• Supports blind hole, cross hole, inclined exit, and stack drilling applications
• Manufactured to ANSI and ISO standards with m7 diameter tolerance for repeatable fit

Compatibility

Designed for use in cast iron and steel workpieces, consistent with Series DC160-05-A0 tooling specifications. Compatible with standard straight-bore collet chucks and drill holders accepting a 0.2360-inch shank diameter.

Installation Notes

Installation and tool changes should be performed with the machine powered down and the spindle fully stopped. Secure the shank in a clean, properly sized collet or chuck to the toolholder manufacturer's recommended clamping torque. This drill does not support coolant-through delivery; external or flood coolant should be directed at the cutting zone when machining steel. Follow applicable ANSI B11 machine safety standards during setup and operation.
