Walter-titex 5058836 Jobber Drill Bit 7/16 in Hss

Product Description

The WALTER-TITEX 5058836 is a jobber-length twist drill bit designed for general-purpose and high-performance drilling in metalworking applications. Manufactured from high speed steel (HSS) with an oxide finish, this bit measures 7/16 inch (0.4375 inch) in diameter and 5-19/32 inches overall length. The standard 118-degree drill point with web thinning reduces thrust and improves centering at the start of the cut. With a regular spiral flute and right-hand cutting direction, this Series A1211 bit suits production shops and maintenance technicians working with ferrous metals on a regular basis.

This drill bit is rated for use in cast iron and steel workpieces, making it a practical choice for blind-hole drilling and stack drilling operations. The 2-flute spiral design with a 3-11/16 inch flute length promotes efficient chip evacuation in these common shop applications. The straight-cylindrical shank at 7/16 inch diameter seats securely in standard three-jaw drill chucks. It conforms to ANSI and ISO standards as well as BS and DIN specification designations, supporting use in both domestic and international manufacturing environments.
