Walter-titex 5058569 Jobber Drill Bit 10mm Hss Oxide A1211

Product Description

The WALTER-TITEX 5058569 is a jobber length twist drill bit designed for general-purpose and high-performance drilling in metalworking applications. It measures 10 mm (0.3937 inches) in diameter with a 133 mm (5-15/64 inches) overall length and a 87 mm (3-27/64 inches) flute length. The bit is manufactured from high speed steel with an oxide coating for improved lubricity and corrosion resistance. A 118-degree standard point angle and web-thinned geometry reduce thrust and improve chip evacuation. Two spiral flutes in a regular helix pattern promote consistent chip removal during through and blind hole drilling.

This drill bit is suited for drilling cast iron and steel in residential, commercial, and industrial fabrication or maintenance settings. Typical applications include blind hole drilling and stack drilling operations where accurate hole sizing and controlled chip flow are required. The Series A1211 designation places this bit in a recognized jobber-length product family manufactured to ANSI, ISO, BS, and DIN standards. It is commonly used by machinists, pipefitters, ironworkers, and maintenance technicians working with structural steel, plate, pipe, and cast iron components.

Key Features

• 10 mm (0.3937 inch) diameter with h8 diameter tolerance for consistent, accurate hole sizing
• Web-thinned, tapered web geometry reduces drill thrust and improves center cutting action
• Oxide finish coating improves surface lubricity and extends service life in ferrous materials
• 118-degree standard point angle suitable for general-purpose drilling in cast iron and steel
• Right-hand, regular spiral flute design with 8xD flute-to-diameter ratio for efficient chip evacuation
• Straight-cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as an OEM-style jobber length drill bit for use in standard drill chucks accepting 0.3937 inch straight-cylindrical shanks. Rated for primary workpiece materials including cast iron (material code K) and steel (material code P) per ISO classification.

Installation Notes

This bit is installed by a machinist or qualified tradesperson into a drill press, handheld power drill, or CNC machine with a compatible chuck capacity. Secure the straight shank firmly in the chuck before operation and verify runout before drilling to avoid premature wear. Use appropriate cutting fluid or coolant when drilling steel to manage heat buildup; note that this bit does not support coolant-through delivery. Follow applicable shop safety protocols and ANSI B11 machine tool standards when operating drilling equipment.
