Walter-titex 5059477 Jobber Drill Bit 3/16 in Hss

Product Description

The WALTER-TITEX 5059477 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 features a parabolic flute geometry and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation. The 130-degree drill point angle handles a range of material hardnesses, while the straight-cylindrical shank seats securely in standard drill chucks. With a 3/16 inch diameter and 3-3/8 inch overall length, this bit fits the A1222 series and conforms to ANSI, ISO, BS, and DIN standards. It is intended for professional machinists and maintenance technicians who require consistent, repeatable hole quality.

This drill bit is suited for blind hole drilling and stack drilling applications in production and maintenance environments. The parabolic flute design provides an 8xD flute-to-diameter ratio, supporting deeper cuts with reliable chip clearance. Primary target materials include cast iron, non-ferrous metals, and steel, making it a practical choice for job shops, HVAC equipment fabrication, industrial maintenance, and metal fabrication work where a standard jobber length is the correct tool reach.

Key Features

• High speed steel construction with oxide coating for wear resistance
• 130-degree drill point angle suited for cast iron, non-ferrous metals, and steel
• Parabolic flute design with 8xD ratio for efficient chip evacuation
• Web-thinned, tapered web reduces cutting resistance and thrust load
• Right-hand cut, straight-cylindrical shank compatible with standard chucks
• Meets ANSI, ISO, BS, and DIN standards; A1222 series designation

Compatibility

Designed for use in standard drill chucks accepting a 3/16 inch straight-cylindrical shank. Suitable for blind hole and stack drilling operations in cast iron, non-ferrous metals, and steel workpieces.

Installation Notes

This bit is installed and operated by machinists or maintenance technicians using a drill press, hand drill, or CNC drilling setup. Secure the straight-cylindrical shank fully in the chuck before operation and verify runout before drilling. Power down or de-energize all equipment before changing bits. Do not exceed the recommended maximum drilling depth of 1.732 inches without retracting to clear chips.
