Walter-titex 5059451 Jobber Drill Bit 19/64 Inch Hss

Product Description

The WALTER-TITEX 5059451 is a jobber-length twist drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from high speed steel (HSS) with an oxide coating, it features a parabolic flute geometry and a web-thinned, tapered web for improved chip evacuation and reduced thrust. The 130-degree split point delivers fast penetration and accurate self-starting entry without a center punch. With a diameter of 19/64 inches (0.2969 inches decimal) and an overall length of 4-19/32 inches, this bit fits standard drill chucks and handles blind hole and stack drilling tasks efficiently.

This drill bit is suited for right-hand cutting operations in cast iron, non-ferrous metals, and steel. It is appropriate for production environments, maintenance shops, and fabrication work where consistent hole quality and tool life matter. The straight cylindrical shank ensures solid chuck retention across standard keyless and keyed chucks. The flute-to-diameter ratio of 8xD supports deeper engagement while maintaining chip clearance, making it a practical choice for both CNC drilling programs and manual drill press setups.

Key Features

• HSS construction with oxide coating for surface hardness and light lubrication retention
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• 130-degree point angle with web thinning reduces entry force and walking
• Straight cylindrical shank compatible with standard drill chucks
• Rated for blind hole drilling and stack drilling applications
• Conforms to ANSI and ISO standards with BS and DIN specification designations

Compatibility

Designed for use in cast iron, non-ferrous metals, and steel workpieces. Suitable for blind hole and stack drilling applications in drill press, handheld, and CNC spindle setups that accept a straight cylindrical shank. Series A1222.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drilling equipment and appropriate feeds and speeds for the workpiece material. Secure the shank fully in the chuck before operation and confirm the spindle is completely stopped before bit changes. Follow applicable shop safety protocols and wear appropriate eye protection. Do not exceed the rated drilling depth of 2.44 inches without clearing chips to prevent bit deflection or breakage.
