Walter-titex 5058336 Jobber Drill Bit No. 51 Hss Oxide

Product Description

The WALTER-TITEX 5058336 is a jobber length drill bit in wire gauge size No. 51, measuring 0.0670 inches in diameter. It is manufactured from high speed steel with an oxide coating for increased surface hardness and basic corrosion resistance. The bit features a standard 118-degree split point, a 2-flute regular spiral configuration, and a web-thinned tapered web to reduce thrust and improve chip evacuation. The straight-cylindrical shank measures 0.0670 inches in diameter and fits standard drill chucks. Overall length is 1-13/32 inches. This bit is suited for production and maintenance drilling work and is installed by machinists, tool and die workers, and general manufacturing technicians.

The 5058336 is designed for drilling into cast iron and steel workpieces. Its tool application ratings cover blind hole drilling and stack drilling operations. The flute length of 7/8 inch supports a maximum drilling depth of 0.748 inches. The Series A1211 designation places this bit in a high-performance general-purpose category within the WALTER-TITEX product line. It is appropriate for light to medium production environments where consistent hole quality in ferrous materials is required.

Key Features

• Wire gauge size No. 51 at 0.0670 inch diameter for precision small-diameter drilling
• High speed steel construction with oxide coating for surface durability
• 118-degree standard drill point angle with web-thinned tapered web reduces entry thrust
• 2-flute regular spiral design promotes efficient chip removal in ferrous materials
• Rated for blind hole and stack drilling applications
• Meets ANSI, ISO, BS, and DIN standards; tolerance class h8 on shank diameter

Compatibility

Designed for use in cast iron and steel workpieces; compatible with standard drill chucks accepting a 0.0670-inch straight-cylindrical shank. Conforms to ANSI and ISO specifications for jobber length drill bits in the 0.0500 to 0.1000 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck rated for the shank diameter. Ensure the workpiece is securely fixtured and the drill press or hand drill is powered off before mounting or removing the bit. Do not exceed the maximum drilling depth of 0.748 inches per pass without retracting to clear chips. Cutting fluid or light oil is recommended when drilling steel to extend tool life and maintain hole tolerance.
