Walter-titex 5058427 Jobber Drill Bit 0.65mm Hss

Product Description

The WALTER-TITEX 5058427 is a jobber length drill bit designed for precision drilling in metalworking applications. Built from high speed steel with an oxide coating, this bit delivers consistent performance in cast iron and steel. It features a 118-degree standard point angle, a spiral flute with regular helix, and a web-thinned tapered web for reduced thrust during entry. The overall length is 1-1/32 inches (26.00 mm), with a flute length of 5/16 inches (8.00 mm). At 0.65 mm in diameter (0.0256 inches decimal), this bit belongs to the Series A1211 and is built to ANSI and ISO standards for consistent dimensional accuracy.

This drill bit is suited for blind hole drilling and stack drilling operations in cast iron and steel workpieces. Its small diameter and high speed steel construction make it appropriate for precision work in tool rooms, production machining, and maintenance environments. The straight-cylindrical shank accepts standard collet chucks and drill press spindles. Licensed trades and machining professionals handling fine-tolerance metalwork in both shop and field settings will find this bit fits standard setups without modification. Maximum drilling depth is 0.272 inches (6.90 mm).

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or trade professionals familiar with drilling operations on metal workpieces. Secure the shank fully in the chuck and verify runout before drilling. Power down and de-energize all equipment before changing bits. Do not exceed the maximum drilling depth of 0.272 inches without retracting to clear chips, as coolant-through is not supported on this bit.
