Walter-titex 5059345 Jobber Drill Bit Letter W 0.386 in

Product Description

The WALTER-TITEX 5059345 is a jobber length drill bit sized to letter W (0.3860 inches decimal), designed for high-performance drilling in production and maintenance environments. Built from high speed steel with an oxide coating, the bit features a parabolic flute geometry and a 130-degree drill point angle with web thinning. Overall length is 5.25 inches, with a flute length of 3.4375 inches. The straight-cylindrical shank and tapered web configuration support accurate chip evacuation and reduced cutting resistance. Licensed tradespeople and machinists working in fabrication, mechanical contracting, and industrial service install this type of tooling.

The 5059345 is suited for blind hole drilling and stack drilling applications. Its parabolic flute and web-thinned point are engineered for primary workpiece materials including cast iron, non-ferrous metals, and steel. Maximum drilling depth is 2.795 inches. The 8xD flute-to-diameter ratio supports deeper penetration without excessive deflection. This bit is appropriate for both manual drill press operation and CNC setup in light to medium production environments.

Installation Notes

Install in a properly rated drill press, hand drill, or CNC spindle using a chuck or collet sized for a 0.3860-inch straight shank. Ensure the workpiece is securely clamped before beginning the cut. Power down or de-energize the machine fully before changing tooling. Do not exceed the drill press or spindle speed rating for the material being cut; consult the manufacturer feed-and-speed reference for high speed steel tooling in the specific workpiece material.
