Precision Twist Drill 5997593 9/32 in Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5997593 is a 9/32 inch (0.2813 inch) diameter jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel with a steam oxide coating, it features a 118-degree standard point angle and a regular spiral flute with web-thinned geometry for cleaner entry and reduced thrust. At 4.25 inches overall length with a 2.9375-inch flute length, this bit fits standard drill chucks via its straight-cylindrical shank. It is suited for production and maintenance drilling operations performed by machinists, maintenance technicians, and trade professionals working with ferrous and non-ferrous metals.

This drill bit is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The steam oxide finish provides mild lubricity and corrosion resistance during cutting. Its jobber-length profile and 10xD flute-to-diameter ratio make it a practical choice for through-hole and blind-hole applications in sheet metal, structural steel, and fabrication work. The Series R10A designation meets ANSI standards and NAS 907 specification requirements, making it appropriate for aerospace and general industrial drilling environments.

Installation Notes

Install in a compatible drill chuck and tighten securely with a chuck key before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to extend tool life and manage heat. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
