Walter-titex 5058721 Jobber Drill Bit 3.3mm Hss Oxide

Product Description

The WALTER-TITEX 5058721 is a jobber length drill bit designed for precision drilling in ferrous materials including cast iron and steel. Manufactured from high speed steel with an oxide coating, this bit runs at a 118-degree standard point angle and features a web-thinned, tapered web configuration that improves chip evacuation and reduces entry force. With an overall length of 2-9/16 inches and a 3.3 mm diameter, the 5058721 is well suited for production and maintenance environments where consistent, repeatable hole quality is required. It is installed by machinists, tooling technicians, and maintenance professionals across industrial and commercial settings.

The 5058721 belongs to the Series A1211 and is engineered for blind hole applications and stack drilling operations. The right-hand spiral flute geometry with a regular spiral type ensures stable cutting action on cast iron and steel workpieces. The straight-cylindrical shank with an h8 diameter tolerance fits standard drill chucks without modification. With a flute-to-diameter ratio of 8xD and a maximum drilling depth of 1.1810 inches (30.00 mm), this bit handles moderate-depth holes in general-purpose production runs. It meets ANSI, ISO, BS, and DIN standards and carries a UNSPSC code of 23241634.

Key Features

• 3.3 mm (0.1299 inch) diameter with h8 tolerance for consistent chuck fit
• 118-degree standard point angle with web thinning for reduced thrust and cleaner entry
• High speed steel construction with oxide coating for heat and wear resistance
• 2-flute right-hand spiral flute design supports efficient chip removal
• Rated for blind hole and stack drilling applications on cast iron and steel
• Compliant with ANSI, ISO, BS, and DIN standards

Compatibility

Designed for use on cast iron and steel workpieces in standard drill press, CNC, and handheld drilling applications. Fits any drill chuck or collet accepting a 0.1299-inch straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with cutting tool setup. Always secure the workpiece and confirm the drill chuck is properly tightened before operation. Run at speeds and feeds appropriate for high speed steel tooling in the target workpiece material. Inspect the cutting edge for wear or chipping before each use and replace the bit if edge integrity is compromised.
