Walter-titex 6968840 Screw Machine Drill Bit 29/64 in

Product Description

The WALTER-TITEX 6968840 is a solid carbide screw machine length drill bit designed for high-performance drilling in demanding production environments. With a 29/64-inch (0.4531 inches) diameter and a 140-degree split point, it delivers clean, accurate entry with reduced thrust. The TiNAl coating extends tool life in abrasive and hard materials. At 4.016 inches overall length, the screw machine format suits short-reach, high-cycle applications in machining centers and drill presses. Two flutes and coolant-through capability support chip evacuation and thermal management during extended cuts. Licensed machinists and tooling professionals install and deploy this bit in production and job shop settings.

This drill bit is rated for universal tool performance across multiple workpiece materials including cast iron, hard materials, non-ferrous metals, and steel. It is well suited for automated machining cells, CNC drilling operations, and manual drill press work where consistent hole quality and tool longevity are priorities. The straight-cylindrical shank fits standard collet chucks and drill chucks accepting a 0.472-inch shank diameter. Its screw machine length format makes it ideal for fixture drilling and confined-reach operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiNAl coating reduces heat buildup and extends tool life in ferrous and non-ferrous applications
• 140-degree drill point angle minimizes thrust and improves self-centering on entry
• Coolant-through design supports internal chip flushing and heat control during deep cuts
• Straight-cylindrical shank compatible with standard collet and drill chuck systems
• Screw machine length format optimized for short-reach, high-cycle production drilling

Compatibility

Designed as a Series DC150-03-A1 screw machine length drill bit suitable for workpiece materials including cast iron, hard material, non-ferrous metal, and steel. Fits tool holders accepting a straight-cylindrical shank of 0.472 inches diameter per the m7 tolerance standard.

Installation Notes

Installation and deployment should be performed by qualified machinists or tooling technicians familiar with rotating cutting tools. Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. Engage coolant supply before drilling when using the coolant-through feature. Never exceed the maximum drilling depth of 1.575 inches without retracting to clear chips.
