Walter-titex 5058748 Jobber Drill Bit 4.1mm Hss Oxide

Product Description

The WALTER-TITEX 5058748 is a jobber-length twist drill bit designed for precision drilling in steel and cast iron. Built from high speed steel with an oxide coating, this bit delivers reliable performance in general-purpose metal drilling applications. It measures 4.1 mm (0.1614 inches) in diameter with an overall length of 2-61/64 inches (75.00 mm). The standard 118-degree point angle and web-thinned geometry reduce entry force and improve chip evacuation. The tapered web and regular spiral flute design make this bit well suited for production environments where consistent hole quality matters. Licensed trades and machining professionals rely on this series for both blind hole and stack drilling operations.

The 5058748 is intended for use in metal fabrication, maintenance, and light industrial drilling where cast iron and steel are the primary workpiece materials. It fits standard drill chucks via its straight-cylindrical shank. The Series A1211 designation places this bit in a high-performance jobber class that meets ANSI, ISO, BS, and DIN standards. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 1.417 inches (36.00 mm), it handles moderate depth holes without excessive tool deflection. Typical settings include manual or CNC drill presses, hand drills, and mill drilling heads used in shops or field service environments.

Key Features

• 118-degree standard point angle with web-thinned geometry for reduced thrust and cleaner entry
• Two-flute regular spiral design promotes efficient chip removal in steel and cast iron
• Straight-cylindrical shank at 0.1614 inches diameter fits standard keyed and keyless drill chucks
• Meets ANSI, ISO, BS, and DIN specifications for dimensional consistency
• Suitable for blind hole and stack drilling applications

Compatibility

Designed for drilling cast iron and steel workpieces. Compatible with any standard drill chuck accepting a 0.1614-inch straight-cylindrical shank. Rated for use in blind hole and stack drilling operations per Series A1211 application guidelines.

Installation Notes

Installation and use should be performed by qualified machinists or tradespeople familiar with metal drilling practices. Secure the workpiece before drilling and verify the chuck is properly tightened before operation. Coolant-through is not supported on this bit, so apply cutting fluid externally when drilling harder steels to manage heat buildup. Do not exceed the maximum drilling depth of 1.417 inches to avoid excessive deflection or bit breakage.
