Walter-titex 5153959 Jobber Drill Bit 17/32 Inch Hss

Product Description

The WALTER-TITEX 5153959 is a jobber-length twist drill bit designed for high-performance hole-making in cast iron, non-ferrous metals, and steel. Built from high speed steel with an oxide coating, this bit measures 17/32 inches (0.5313 inches decimal) in diameter with an overall length of 6-5/16 inches. The parabolic flute geometry provides efficient chip evacuation during deep drilling operations. The web-thinned, tapered web design reduces thrust and improves point entry. This bit is suited for production drilling environments where consistent performance and accuracy are required, and it is typically installed and operated by machinists, maintenance mechanics, and metalworking tradespeople.

The 5153959 is built for demanding applications including blind hole drilling and stack drilling in cast iron, steel, and non-ferrous metals. The Series A1222 designation places this bit in a high-performance category conforming to ANSI, ISO, BS, and DIN standards. With a flute-by-diameter ratio of 8xD, it handles deeper reach jobs while maintaining chip flow. The straight-cylindrical shank fits standard drill chucks without adapters, making it compatible with common floor-standing drill presses, CNC machining centers, and handheld power tools configured for this shank diameter.

Key Features

• 17/32 inch diameter (0.5313 inches decimal) with h8 diameter tolerance for precision fits
• High speed steel construction with oxide coating for heat resistance and surface protection
• Parabolic flute design promotes fast chip evacuation and reduces heat buildup
• Web-thinned tapered web reduces cutting resistance and improves point stability
• 130-degree drill point angle optimized for steel and cast iron entry
• Rated for blind hole and stack drilling applications per Series A1222 spec

Compatibility

The 5153959 is designed for use in applications involving cast iron, non-ferrous metals, and steel workpieces. Primary workpiece material codes K, N, O, and P apply. Straight-cylindrical shank accepts standard drill chuck sizes matching 17/32 inch shank diameter.

Installation Notes

Installation and operation of this drill bit should be performed by qualified machinists or maintenance mechanics familiar with metalworking equipment. Always secure the workpiece fully before drilling and confirm the chuck is tightened properly before starting the spindle. Coolant-through is not supported on this bit; use appropriate external cutting fluid for the workpiece material when required. Follow machine manufacturer guidelines and applicable ANSI safety standards for rotating tooling.
