Walter-titex 5058359 No 72 Hss Jobber Drill Bit

Product Description

The WALTER-TITEX 5058359 is a jobber length drill bit in wire gauge size No. 72, measuring 0.0250 inches in diameter. It is manufactured from high speed steel with an oxide coating for added wear resistance. The bit features a standard 118-degree split point, a regular spiral flute, and a straight-cylindrical shank. Overall length is 1 inch, with a flute length of 5/16 inch and a maximum drilling depth of 0.272 inch. This bit is designed for precision drilling in tight-tolerance applications and is installed by machinists, tool and die makers, and maintenance technicians working with small-diameter holes.

This drill bit is suited for drilling cast iron and steel in both blind hole and stack drilling applications. The web-thinned, tapered web construction reduces thrust force on entry and helps maintain hole position in production and repair environments. At 1 inch overall length, it fits standard drill chucks and CNC tool holders used in bench drill presses, hand drills, and machining centers where small wire gauge bits are required.

Key Features

• 118-degree standard point angle with web thinning for reduced entry thrust
• High speed steel construction with oxide coating for wear resistance
• Right hand cut, 2-flute regular spiral design for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Rated for blind hole and stack drilling on cast iron and steel workpieces

Compatibility

Designed for use in cast iron and steel workpieces; suitable for blind hole and stack drilling operations across Series A1211 tooling applications per ANSI and ISO standards.

Installation Notes

This bit is installed and serviced by machinists and maintenance technicians using standard drill chucks or collets sized for 0.0250 inch shanks. Ensure the drill press or machining center spindle is fully stopped and locked out before bit changes. Use appropriate cutting fluid for ferrous materials to extend tool life and maintain dimensional accuracy. Do not exceed the maximum drilling depth of 0.272 inch per plunge without retracting to clear chips.
