Walter-titex 5058407 Jobber Drill Bit 0.45mm Hss Oxide

Product Description

The WALTER-TITEX 5058407 is a jobber length drill bit designed for precision drilling in ferrous materials including cast iron and steel. Built from high speed steel with an oxide coating, this bit measures 0.45 mm (0.0177 inches) in diameter and delivers a 20.00 mm overall length. The 118-degree standard point angle and web-thinned tip reduce entry force and help center the bit without wandering. A two-flute spiral configuration with regular spiral type provides efficient chip evacuation during operation. This bit is suited for use by machinists, maintenance technicians, and fabricators working with small-diameter precision holes in production or repair environments.

The 5058407 is engineered for blind hole drilling and stack drilling applications in cast iron and steel workpieces. Its straight-cylindrical shank with a diameter of 0.0177 inches seats securely in standard drill chucks and collets. The Series A1211 design follows ANSI, ISO, BS, and DIN standards, making it compatible with metric and inch-based machining setups. The maximum drilling depth is 4.20 mm (0.1650 inches), and the flute length is 5.00 mm, which supports controlled chip removal in shallow-depth operations. This is a high-performance, general-purpose grade bit appropriate for repetitive production drilling at small diameters.

Key Features

• 0.45 mm diameter with h8 diameter tolerance for tight, repeatable fitment
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust force
• Oxide finish on high speed steel body for surface hardness and light lubricity
• Right-hand cut, two-flute spiral configuration for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Conforms to ANSI, ISO, BS, and DIN standards for broad application compatibility

Compatibility

Designed for drilling cast iron and steel workpieces in blind hole and stack drilling applications. The straight-cylindrical shank fits standard drill chucks and collets sized for 0.0177-inch shank diameters. Part of the Series A1211 product line covering drill sizes from 0.0000 to 0.0500 inches in the decimal inch range.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance technicians familiar with small-diameter drilling procedures. Secure the workpiece firmly before drilling to prevent movement that can snap bits at this diameter. Ensure the drill chuck is clean and properly tightened to the shank before operation. Coolant-through is not supported on this bit; use appropriate external cutting fluid when working with harder steels to extend tool life.
