Walter-titex 5058356 Jobber Drill Bit No. 7 Hss Oxide

Product Description

The WALTER-TITEX 5058356 is a jobber-length, high speed steel drill bit in wire gauge size No. 7, equivalent to 0.2010 inches in decimal diameter. Finished with an oxide coating for improved lubricity and basic corrosion resistance, this bit features a 118-degree standard point angle, a 2-flute right-hand spiral flute configuration, and a straight-cylindrical shank. Overall length is 3-3/8 inches with a flute length of 2-1/16 inches. The tapered web and web-thinned geometry reduce cutting resistance, making this bit well suited for consistent, repeatable hole production in metalworking applications. It meets ANSI and ISO standards and is manufactured to an h8 diameter tolerance.

This drill bit is designed for use in cast iron and steel workpieces in both blind hole and stack drilling applications. The Series A1211 designation places it in a high-performance general-purpose category appropriate for production and maintenance environments. A maximum drilling depth of 1.7320 inches and a regular spiral type support chip evacuation in through and blind hole work. Licensed machinists, tool-and-die technicians, millwrights, and skilled maintenance mechanics are the typical end users. It is suitable for use in drill presses, CNC machining centers, and hand-held power tools with compatible chuck capacity.

Installation Notes

Install in a properly rated drill chuck and verify chuck key is removed before powering the machine. Secure the workpiece firmly before drilling to prevent movement during cutting. Follow applicable shop safety practices and machine tool operating procedures. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
