Walter-titex 7378449 Carbide Jobber Drill Bit 0.1575 in

Product Description

The WALTER-TITEX 7378449 is a solid carbide jobber-length drill bit designed for precision hole-making in ferrous materials including cast iron and steel. Built to Series DC160-05-A0 specifications, it features a 140-degree drill point angle that improves centering and reduces thrust in hard materials. The dual TiSiAlCrN and AlTiN coating stack delivers high heat resistance and wear resistance, extending tool life in production drilling environments. At 0.1575 inches in diameter with a 2.913-inch overall length and a 5xD flute-to-diameter ratio, this bit is suited for shops and field machinists running tight-tolerance work to ANSI and ISO standards.

This drill bit is intended for use in ferrous metal applications, specifically cast iron and steel workpieces. It supports blind hole, cross hole, inclined hole exit, and stack drilling configurations, making it a versatile choice for machining centers, CNC drilling operations, and manual drill press setups. The straight-cylindrical shank at 0.236 inches diameter fits standard collet and chuck systems. Maximum drilling depth reaches 1.142 inches, appropriate for through and blind-hole work within its 5xD capacity.

Key Features

• Solid carbide construction in material grade WJ30ET for rigidity and long tool life
• Dual coating — AlTiN and TiSiAlCrN — provides thermal and oxidation resistance in dry and semi-dry cutting
• 140-degree split point geometry improves self-centering and reduces walking on hard surfaces
• Right-hand cut, 2-flute design optimized for chip evacuation in steel and cast iron
• Diameter tolerance m7 ensures consistent fit in precision toolholders
• Meets ANSI and ISO standards for interchangeable use across compatible tooling systems

Compatibility

Designed as an OEM-style replacement and standard production drill bit for machining applications involving cast iron and steel workpieces, compatible with any toolholder or drill chuck accepting a 0.236-inch straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in the collet or chuck to the recommended grip depth before operation, and verify runout with a dial indicator on precision setups. This bit does not support through-coolant delivery — use external coolant or cutting fluid appropriate for the workpiece material. Follow shop-specific feeds and speeds for solid carbide tooling in the applicable workpiece material to avoid premature edge failure.
