Walter-titex 5058710 Jobber Drill Bit 25/64 in Hss

Product Description

The WALTER-TITEX 5058710 is a jobber-length twist drill bit engineered for general-purpose hole-making in metal fabrication and industrial machining applications. Manufactured from high speed steel with an oxide finish, this bit measures 25/64 inches (0.3906 inches decimal) in diameter with a 5.25-inch overall length and a 3.4375-inch flute length. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and improve chip evacuation. The straight-cylindrical shank seats securely in standard three-jaw chucks and collet systems. This bit is built to ANSI and ISO standards and carries a Series A1211 designation, placing it within a well-established line of high-performance jobber drills used across metalworking trades.

This drill bit is suited for blind hole drilling and stack drilling in cast iron and steel workpieces. The regular spiral flute geometry and right-hand cutting direction make it compatible with conventional drill press, lathe, and handheld power tool setups. The oxide coating provides moderate lubricity and corrosion resistance during dry or light-lubricated cutting operations. Machinists, toolroom technicians, pipefitters, and maintenance mechanics frequently spec this type of bit for structural steel, pipe, and plate work where a reliable, consistent hole tolerance is required.

Key Features

• High speed steel construction with oxide coating for extended tool life in ferrous materials
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust and cleaner entry
• 2-flute regular spiral design promotes efficient chip clearance in blind hole and stack drilling
• Straight-cylindrical shank (25/64 inches diameter) fits standard chucks and collet holders
• Meets ANSI and ISO standards; also referenced to BS and DIN specification designations
• Maximum drilling depth of 2.795 inches supports through-hole and moderate-depth blind-hole work

Compatibility

Designed for use in cast iron and steel workpieces. Suitable for blind hole and stack drilling applications. Fits any standard drill chuck or collet accepting a 25/64-inch straight-cylindrical shank.

Installation Notes

This bit is installed and used by machinists, toolroom personnel, and maintenance mechanics operating drill presses, lathes, or power hand tools. Ensure the shank is fully seated and the chuck is tightened before operation. Use appropriate cutting fluid or lubricant when drilling steel to manage heat and extend tool life. Inspect the cutting edges and point before each use and replace the bit if chipping or dulling is observed.
