Walter-titex 5059472 Jobber Drill 3.50mm Hss Oxide

Product Description

The WALTER-TITEX 5059472 is a 3.50 mm high speed steel jobber drill designed for precision drilling in ferrous and non-ferrous materials. Built to DIN 338 and compliant with ANSI and ISO standards, this drill features a 130-degree split point geometry with web thinning for reduced thrust and accurate self-centering on entry. The parabolic flute design promotes efficient chip evacuation at higher feed rates. The oxide coating provides mild corrosion resistance and reduces galling during cutting. With an overall length of 2.756 inches and a straight-cylindrical shank, it fits standard drill chucks without modification. Intended for use by machinists, tool-and-die professionals, and maintenance technicians working on production or field drilling tasks.

The 5059472 is rated for drilling into cast iron, non-ferrous metals, and steel, covering primary workpiece material codes K, N, and P. It is suited for blind hole drilling and stack drilling applications where consistent point geometry and chip clearance are critical. The flute-to-diameter ratio of 8xD and a maximum drilling depth of 1.299 inches make it appropriate for through-hole and shallow blind-hole work in both manual and CNC-fed setups. The Series A1222 designation places it within a standardized jobber-length family for repeatable tooling inventory management.

Key Features

• 3.50 mm diameter with h8 tolerance for close-tolerance hole sizing
• 130-degree UFL split point with web thinning reduces entry thrust and walk
• Parabolic flute geometry improves chip evacuation in deep and stack drilling
• M2 high speed steel construction balances toughness and wear resistance
• Oxide finish provides corrosion resistance and reduces chip adhesion
• DIN 338 specification with ANSI and ISO compliance for standardized tooling programs

Compatibility

Designed as a DIN 338 Series A1222 jobber-length drill suitable for use in standard straight-shank drill chucks and collet holders accommodating a 3.50 mm straight-cylindrical shank. Rated for cast iron, non-ferrous metal, and steel workpiece materials.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drill press, lathe, or CNC spindle tooling procedures. Secure the straight shank fully within the chuck or collet to the recommended engagement depth before operation. Ensure the spindle and workpiece are properly fixtured before initiating a cut. This tool does not support coolant-through delivery; use external cutting fluid appropriate to the workpiece material when drilling steel or cast iron at higher feed rates.
