Walter-titex 7378130 Screw Machine Drill Bit 0.2205 in

Product Description

The WALTER-TITEX 7378130 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. It measures 0.2205 inches in diameter with a 2.598-inch overall length and features a 140-degree X treme Evo point for precise entry and reduced walking on hard or abrasive materials. The coated finish extends tool life by reducing friction and heat buildup during operation. With two flutes and coolant-through capability, this bit is built for consistent chip evacuation and thermal management in high-cycle CNC and manual machining environments. Machinists, tool-and-die workers, and mechanical contractors specify this series for production drilling operations.

This drill bit is suited for screw machine length applications where stub-length rigidity is required in a compact form factor. Primary workpiece materials include cast iron, hard materials, non-ferrous metals, and steel, making it a versatile choice across fabrication, HVAC equipment manufacturing, and mechanical assembly operations. The Universal Advance tool performance rating indicates broad material compatibility without requiring specialized machine parameters. The straight-cylindrical shank fits standard drill chucks and collet holders without modification.

Key Features

• Solid carbide construction with coated finish for extended wear resistance in hard and abrasive materials
• 140-degree X treme Evo point type for accurate positioning and reduced thrust on entry
• Coolant-through design supports internal coolant delivery for thermal control in high-speed applications
• Screw machine (stub) length provides added rigidity over jobber-length bits in tight setups
• Right-hand cut with 2-flute geometry for efficient chip evacuation
• Meets DIN and ISO standards; material grade WJ30ET with m7 diameter tolerance

Compatibility

Designed as a direct-fit replacement or production-use drill bit within the WALTER-TITEX DC160-03-A1 series, compatible with workpieces of cast iron, hard material, non-ferrous metal, and steel as specified by the manufacturer. Fits standard straight-cylindrical chuck and collet systems accepting a 0.2360-inch shank diameter.

Installation Notes

This bit is installed by machinists and tooling technicians in CNC machining centers, drill presses, or screw machines. Secure the straight-cylindrical shank fully in a collet or drill chuck before operation and verify runout is within acceptable tolerance for the application. Engage internal coolant supply if available to take full advantage of the coolant-through channel design. Inspect the cutting edge and coating condition before each production run to avoid premature wear or workpiece damage.
