Walter-titex 8325156 Carbide Drill Bit 3/8 Inch Zrn

Product Description

The WALTER-TITEX 8325156 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding materials. Built to the DC180 series standard, it features a 3/8 inch (0.3750 inch decimal) diameter with a 140-degree split point angle for accurate self-centering entry and reduced thrust. The ZrN (zirconium nitride) coating extends tool life and improves chip evacuation in abrasive materials. With coolant-through capability and a regular right-hand spiral, this bit maintains consistent cutting performance at depth. It is sized for professional machining environments where dimensional accuracy and tool longevity are critical.

This drill bit suits precision drilling applications in metal fabrication, aerospace component work, mold and die shops, and general machining. The 8xD flute-to-diameter ratio supports drilling up to 3.1496 inches deep without regrinding. The cylindrical shank diameter of 0.3937 inches fits standard drill chucks and collet systems. It is sold as a single-piece unit and is suited for CNC machining centers and manual drill press setups where solid carbide tooling is specified.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• ZrN coating reduces friction and extends tool life in abrasive applications
• 140-degree point angle for self-centering and reduced walking on entry
• Coolant-through design supports high-speed drilling and chip flushing at depth
• Regular right-hand spiral with 2 flutes for efficient chip removal
• 8xD flute ratio allows drilling up to 3.1496 inches deep

Compatibility

Designed as a direct-fit solid carbide drill bit for use in standard drill chucks, ER collet systems, and CNC tool holders accepting a 0.3937 inch cylindrical shank.

Installation Notes

Installation and operation should be performed by qualified machinists or tool-and-die professionals familiar with carbide tooling requirements. Always confirm spindle speed and feed rate are appropriate for solid carbide before running. Secure the shank fully in the collet or chuck to the specified grip depth before cycling the machine. Inspect the cutting edges and coating condition before each use, as chipped carbide tooling should not be run.
