Walter-titex 5058316 Jobber Drill Bit No.33 Hss Oxide

Product Description

The WALTER-TITEX 5058316 is a jobber-length twist drill bit sized to wire gauge No. 33 (0.1130 inches decimal) and designed for high-output production drilling in trade and industrial settings. Manufactured from high speed steel with an oxide finish coating, it features a 118-degree standard point angle and a regular spiral flute geometry with a tapered, web-thinned web configuration. The 2-flute, right-hand-cut design delivers efficient chip evacuation. Overall length is 2-13/32 inches, with a straight-cylindrical shank diameter of 0.1130 inches. The bit is web-thinned for improved penetration and reduced thrust at entry, making it well suited for demanding hole work in ferrous materials.

This drill bit is rated for use in cast iron and steel workpieces and supports both blind hole and stack drilling applications. The Series A1211 designation places it in a general-purpose, high-performance jobber class built to ANSI and ISO standards with BS and DIN specification compliance. It is a standard choice for machinists, tool-and-die shops, maintenance technicians, and fabrication tradespeople working on steel structures, castings, or assemblies where consistent hole diameter and finish matter. The flute-to-diameter ratio of 8xD and a maximum drilling depth of 1.1020 inches (28.00 mm) define the practical limits of this bit in typical setups.

Designed for use in cast iron and steel workpieces as stated in product specifications. Suitable for standard drill chucks and collets accepting a 0.1130-inch straight-cylindrical shank. No specific machine model compatibility is listed in the available product data.

Installation Notes

This bit is installed and operated by machinists and general tradespeople using drill presses, CNC drilling centers, or hand-held power drills with appropriate chuck capacity. Secure the straight-cylindrical shank firmly in the chuck before operation and verify the chuck is rated for the intended spindle speed. Do not exceed the maximum drilling depth of 1.1020 inches in a single pass without retracting to clear chips. Cutting fluid or coolant is recommended when drilling steel to extend bit life, though this tool is not designed for coolant-through delivery.
