Walter-titex 5058685 Jobber Drill Bit 2.3mm Hss A1211

Product Description

The WALTER-TITEX 5058685 is a jobber length twist drill bit designed for precision drilling in metal and cast iron applications. Built from high speed steel with a bright uncoated finish, it measures 2.3 mm (0.0906 inches) in diameter with an overall length of 53.00 mm (2-3/32 inches). The 118-degree standard point angle and web-thinned tip reduce entry force and improve centering on entry. With a regular spiral flute and tapered web configuration, this bit maintains chip evacuation efficiency across its 27.00 mm (1-1/16 inches) flute length. It is part of the Series A1211 line and carries ANSI and ISO standards compliance.

This drill bit is suited for blind hole drilling and stack drilling operations on cast iron and steel workpieces. The straight-cylindrical shank with an 0.0906-inch shank diameter fits standard drill chucks without adapters. A maximum drilling depth of 23.00 mm (0.9060 inches) makes it appropriate for typical through-hole and shallow blind-hole work in fabrication, maintenance, and mechanical assembly environments. The 2-flute spiral design provides balanced cutting action at moderate feed rates. It is commonly used by machinists, maintenance technicians, and trade professionals requiring consistent small-diameter hole placement in production or field conditions.

Key Features

• High speed steel construction rated for general purpose drilling in cast iron and steel
• 118-degree standard point with web thinning for reduced thrust and accurate self-starting entry
• Regular spiral flute with 8xD flute-to-diameter ratio for consistent chip evacuation
• Bright uncoated finish suitable for use with standard cutting fluids or dry drilling
• Straight-cylindrical shank fits conventional drill chucks without special tooling
• ANSI and ISO compliant; DIN and BS specification designations

Compatibility

Designed as a general purpose jobber length drill bit for use in standard drill chucks accepting a 0.0906-inch straight-cylindrical shank. Compatible with primary workpiece materials cast iron and steel per material codes K and P.

Installation Notes

This bit is installed and operated by machinists or trade technicians using drill presses, hand drills, or CNC equipment that accepts straight-shank tooling. Secure the shank firmly in the chuck before operation and confirm runout is within acceptable tolerances. Coolant-through is not supported; apply cutting fluid externally when drilling steel to extend tool life. Inspect the cutting edges for wear or chipping before each use, as small-diameter bits are susceptible to breakage under side load or misalignment.
