Walter-titex 5059431 Jobber Drill Bit 11/32 Inch Hss

Product Description

The WALTER-TITEX 5059431 is a jobber-length drill bit designed for high-performance drilling in cast iron, non-ferrous metals, and steel. Built from high speed steel with an oxide coating, it measures 11/32 inch (0.3438 inch decimal) in diameter with a 4-29/32 inch overall length and a 3-3/16 inch flute length. The 130-degree drill point angle and web-thinned, tapered web design reduce entry force and improve chip evacuation. This bit is suited for blind hole drilling and stack drilling applications where consistent performance across multiple workpiece materials is required. It conforms to ANSI, ISO, BS, and DIN standards.

The 5059431 fits into production and maintenance drilling workflows across metalworking, fabrication, and mechanical contracting environments. The parabolic flute geometry, rated at an 8xD flute-to-diameter ratio, supports efficient chip removal in deeper cuts. The straight-cylindrical shank seats directly in standard drill chucks without adapters. Typical applications include structural steel work, cast iron component drilling, and stack drilling of sheet assemblies in light manufacturing or mechanical service settings.

Key Features

• High speed steel construction with oxide coating for wear resistance
• 130-degree drill point angle with web-thinned, tapered web for reduced thrust and clean entry
• Parabolic flute design at 8xD ratio for efficient chip evacuation in deeper holes
• Right-hand cut, straight-cylindrical shank fits standard drill chucks directly
• Rated for cast iron, non-ferrous metals, and steel workpieces
• Meets ANSI, ISO, BS, and DIN standards; Series A1222

Compatibility

Designed as a direct-fit replacement or standard addition for jobber-length drill applications using Series A1222 high performance HSS bits. Compatible with workpiece materials coded K (cast iron), N (non-ferrous metals), and P (steel) per ISO material classification. Suitable for blind hole and stack drilling tool setups.

Installation Notes

Installation is performed by machinists or qualified maintenance technicians using a standard drill press, hand drill, or CNC spindle with an appropriate drill chuck. Ensure the shank is fully seated and the chuck is tightened securely before operation. Disconnect or de-energize the drilling machine before changing bits. Do not exceed the maximum drilling depth of 2.598 inches without retracting to clear chips when using parabolic flute bits in deeper holes.
