Walter-titex 7378318 Screw Machine Drill Bit 0.5354 in Carbide

Product Description

The WALTER-TITEX 7378318 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to Series A3299XPL specifications, this bit features a 0.5354-inch (13.60 mm) diameter, a 140-degree X-treme point, and coolant-through capability for extended tool life in difficult materials. The straight-cylindrical shank and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. Licensed machinists, tool-and-die professionals, and CNC operators are the primary users of this type of tooling in production environments.

This drill bit is suited for precision drilling in cast iron, hardened and general-purpose steel, and non-ferrous metals. The screw machine length format provides added rigidity compared to jobber-length bits, making it a reliable choice for short-hole drilling on machining centers, turret lathes, and CNC drill presses. The Universal Advance performance classification and 3xD flute-to-diameter ratio support consistent, repeatable results across production runs. It carries DIN and ISO standards designation.

Key Features

• Solid carbide construction with coated finish for wear resistance in hard and abrasive materials
• 140-degree X-treme point reduces thrust and self-centers without a pilot hole in many setups
• Coolant-through design channels fluid directly to the cutting zone for heat management and chip removal
• Web-thinned, tapered web lowers cutting forces and improves penetration in cast iron and steel
• Straight-cylindrical shank fits standard drill chucks and collet holders without modification
• DIN and ISO standards compliance supports use in regulated production and quality environments

Compatibility

Designed for use in CNC machining centers, turret lathes, and drill presses equipped with standard straight-shank toolholders. Rated for primary workpiece materials including cast iron, hard material, non-ferrous metal, and steel. Drill bit size falls within the A3299XPL series range of 0.5000 to 0.6000 inches (13.50 to 17.00 mm).

Installation Notes

Installation and operation should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before chucking the bit. Carbide tooling is brittle — avoid side loads, interrupted cuts without proper feed rate adjustment, or dropping the bit on hard surfaces. Verify coolant-through connections are active before running at rated feed and speed parameters.
